Where to Buy Heparin Blood Collection Tubes in the U.S.

Summary

• Major U.S. sources for Heparin blood collection tubes include BD, Greiner Bio-One, SARSTEDT, Cardinal Health, McKesson, Medline, Fisher Scientific, and other authorized laboratory distributors.
• Buyers should distinguish lithium-Heparin, sodium-Heparin, and plasma-separator tubes, while checking tube size, draw volume, additive concentration, sterility, expiration date, and analyzer compatibility.
• Reliable purchasing requires verification of regulatory status, lot traceability, storage conditions, shipping performance, and total cost rather than comparing unit price alone.

Heparin blood collection tubes are widely used in hospitals, physician offices, urgent-care centers, reference laboratories, research facilities, and Mobile Phlebotomy services throughout the United States. They are most commonly associated with green or light-green tube tops and are designed to produce plasma rather than serum. Depending on the additive and tube design, they may be used for chemistry testing, selected immunoassays, blood-gas-related procedures, molecular workflows, and specialized laboratory applications.

For a U.S. purchaser, the central question is not simply whether a company sells “green-top tubes.” The more important questions are which type of Heparin is included, whether the tube contains a gel separator, whether the product is cleared or otherwise appropriate for the intended use, whether it fits the laboratory’s analyzers and centrifuges, and whether the supplier can provide consistent inventory and lot documentation.

Several manufacturers make Heparin blood collection tubes for the American market. These products are sold directly in some cases and through laboratory, medical, and industrial distributors in others. The leading purchasing channels include original manufacturers, national healthcare distributors, laboratory-supply companies, regional distributors, and approved group-purchasing organizations.

What Are Heparin Blood Collection Tubes?

Heparin is an Anticoagulant that prevents clot formation by enhancing the activity of antithrombin and inhibiting key coagulation factors. In blood collection tubes, the additive allows the blood to remain unclotted so that plasma can be separated after centrifugation. This differs from serum tubes, in which the specimen is allowed to clot before the serum is recovered.

Most Heparin tubes used for routine venous blood collection contain either lithium Heparin or sodium Heparin. Lithium Heparin is commonly selected for clinical chemistry because lithium is less likely than sodium to interfere with many commonly measured analytes. Sodium-Heparin tubes may be appropriate when lithium contamination could affect testing or when a laboratory method specifically calls for sodium Heparin.

Heparin tubes are available in several configurations. A plain Heparin tube contains the Anticoagulant without a gel barrier. A plasma-separator tube, often called a PST, contains lithium Heparin and a polymer gel that forms a barrier between cells and plasma after centrifugation. Some products are manufactured for trace-element, pediatric, or special chemistry applications and may have different materials, fill volumes, or additive concentrations.

Common Heparin tube types

1. Lithium-Heparin tubes: These are frequently used for general plasma chemistry testing and are available in both standard and plasma-separator formats.

2. Sodium-Heparin tubes: These may be chosen for tests requiring sodium Heparin or for situations in which lithium could be a source of analytical interference.

3. Lithium-Heparin plasma-separator tubes: These tubes contain a gel barrier and are intended to simplify plasma separation and reduce contact between cells and plasma.

4. Heparinized capillary or specialized collection products: These are used in selected blood-gas, pediatric, point-of-care, or research procedures and should not be substituted for standard evacuated tubes without method verification.

Leading Manufacturers Available in the United States

The following manufacturers are among the best-known sources for Heparin blood collection tubes sold in the United States. Product availability changes by catalog, region, contract, and inventory level, so purchasers should confirm the current product number and intended application with the manufacturer or authorized distributor.

BD

BD, through its BD Vacutainer product line, is one of the most established suppliers of evacuated blood collection systems in the United States. Its portfolio includes lithium-Heparin tubes, sodium-Heparin tubes, and plasma-separator products. Many laboratories identify BD tubes by the familiar green-top or light-green-top format, although color conventions can vary by product and market.

BD tubes are commonly purchased by acute-care hospitals, outpatient laboratories, physician practices, and reference laboratories. The company offers multiple tube sizes and configurations, including products intended for routine chemistry, pediatric collection, and specialized workflows. Buyers should review the individual package insert because a light-green tube from one product family may not have exactly the same additive, gel, draw volume, or recommended testing profile as another.

BD products are available through direct institutional purchasing and through large distributors such as Cardinal Health, McKesson, Medline, and laboratory-supply companies. Contract pricing may be available through hospital systems and group-purchasing organizations. For high-volume users, the ability to obtain stable lot supply and compatible accessories may be as important as the initial quoted price.

Greiner Bio-One

Greiner Bio-One supplies VACUETTE blood collection tubes in the United States. Its product range includes lithium-Heparin and sodium-Heparin tubes, as well as plasma-separator tubes. The VACUETTE system uses its own tube, stopper, labeling, and color-coding specifications, so facilities should evaluate the entire collection system rather than comparing tube color alone.

Greiner Bio-One products are used in hospitals, independent laboratories, research settings, and outpatient collection sites. The company offers different sizes, fill volumes, and additive options. Some facilities select VACUETTE products as part of a dual-source strategy, while others standardize on the brand across their entire phlebotomy operation.

When moving from another manufacturer to Greiner Bio-One, laboratories should verify specimen requirements with the laboratory medical director and review analyzer validation or verification requirements. Even when two tubes are both labeled lithium Heparin, differences in gel, tube material, stopper composition, vacuum, or surface treatment may affect specimen quality or test performance.

SARSTEDT

SARSTEDT provides blood collection products, including S-Monovette and related collection systems, for the U.S. laboratory market. Depending on the product line and collection method, the company offers heparinized tubes and containers designed for clinical and research applications.

SARSTEDT is particularly relevant for laboratories evaluating alternatives to conventional evacuated collection systems or for organizations that use a broader specimen-collection platform. Its products may differ from standard evacuated tubes in how blood is drawn, transferred, or handled. A purchaser should confirm whether the product is intended for routine Venipuncture, syringe transfer, pediatric collection, or a specialized application.

Because the S-Monovette system can involve aspiration or vacuum modes, staff training and Workflow assessment are important. A product can be technically suitable but operationally inconvenient if the site lacks the appropriate holders, adapters, needles, or staff familiarity.

Other specialized manufacturers

Additional manufacturers may sell heparinized blood collection products for specific applications. These can include companies serving point-of-care diagnostics, blood-gas testing, pediatric collection, research laboratories, and specialty specimen management. Some manufacturers focus on capillary tubes, microcollection systems, or accessories rather than conventional adult evacuated tubes.

Examples of companies that may appear in U.S. laboratory and medical-supply catalogs include Sekisui Medical, Terumo, and specialty diagnostic-product manufacturers. Their availability can be more application-specific than that of BD or Greiner Bio-One. Before purchasing, confirm that the tube is intended for human diagnostic specimen collection if it will be used in a clinical laboratory, rather than assuming that a research-grade tube is appropriate for patient testing.

National U.S. Distributors That Sell Heparin Tubes

Many organizations do not buy directly from the tube manufacturer. Instead, they purchase through national distributors that combine blood collection tubes with needles, holders, tourniquets, labels, gauze, sharps containers, and other phlebotomy products. This approach can reduce the number of purchase orders and simplify contract management.

Cardinal Health

Cardinal Health is a major healthcare distributor serving hospitals, laboratories, clinics, physician practices, and other healthcare organizations. Its medical-supply catalogs commonly include blood collection tubes from major manufacturers, including green-top Heparin products.

Cardinal Health may be useful for organizations seeking consolidated purchasing, scheduled deliveries, and account-level contract pricing. Buyers should confirm whether the listed product is manufacturer-direct, distributor-branded, or an equivalent item. A catalog description such as “green-top plasma tube” is not sufficient by itself; the product number and manufacturer specifications should be checked.

McKesson

McKesson is another major U.S. healthcare distributor with broad laboratory and medical-supply coverage. Its catalog may include lithium-Heparin tubes, sodium-Heparin tubes, plasma-separator tubes, pediatric products, and compatible blood collection accessories.

McKesson can be a practical source for independent clinics and smaller laboratories that need routine replenishment but do not have the purchasing volume to negotiate directly with a manufacturer. Availability, minimum-order requirements, substitutions, and shipping schedules should be reviewed carefully. During periods of supply disruption, distributors may offer substitute products, but substitutions should not be accepted without laboratory approval and compatibility review.

Medline

Medline supplies a wide range of clinical and laboratory products to U.S. healthcare facilities. Its distribution network may offer branded Heparin tubes and related phlebotomy supplies. Medline is often considered by outpatient clinics, long-term-care organizations, ambulatory surgery centers, and hospital departments that want to consolidate routine medical-supply purchases.

When purchasing through Medline or any broadline distributor, the buyer should verify the actual manufacturer, catalog number, tube dimensions, and expiration date. A broadline distributor may list several similar tubes under neighboring catalog entries, and the difference between a plain Heparin tube and a plasma-separator tube can be significant for laboratory Workflow.

Fisher Scientific

Fisher Scientific is a widely used source for laboratory supplies, diagnostics, and research products. Its U.S. catalog commonly includes blood collection tubes from BD, Greiner Bio-One, SARSTEDT, and other manufacturers. Fisher may be especially convenient for universities, research institutions, independent laboratories, biotechnology companies, and hospitals that already maintain a laboratory purchasing account.

Fisher’s catalog structure makes it possible to compare tube manufacturers and specifications, but buyers should avoid relying only on search terms. A search for “Heparin tube” may return evacuated tubes, microtubes, capillary products, blood-gas devices, and research-only items. Each product must be reviewed for intended use, regulatory status, size, additive, and packaging.

Henry Schein and regional distributors

Henry Schein and regional medical, dental, and laboratory distributors may also stock Heparin blood collection tubes. These sources can be useful for physician offices, urgent-care centers, Mobile Phlebotomy companies, and smaller practices that need modest quantities and fast delivery.

Regional distributors sometimes provide more personalized service than national suppliers, including standing orders, local delivery, and assistance with product substitutions. However, they may not carry every tube size or manufacturer. A healthcare organization should confirm the distributor’s ability to provide lot numbers, certificates or manufacturer documentation when required, and a reliable process for handling damaged or temperature-exposed shipments.

How to Choose the Correct Heparin Tube

Tube selection should begin with the laboratory test menu rather than the preferred brand. The laboratory should identify whether each test requires plasma, serum, whole blood, or another specimen type. It should then confirm the required Anticoagulant and tube format using the test manufacturer’s instructions, the laboratory’s procedure manual, and applicable laboratory guidance.

Important specifications to compare

1. Heparin type: Determine whether the test requires lithium Heparin, sodium Heparin, or another formulation. Do not assume that lithium and sodium Heparin are interchangeable for every assay.

2. Tube volume: Common evacuated tubes may range from pediatric or microcollection sizes to larger adult tubes. The volume must be sufficient for the ordered tests and appropriate for the analyzer’s sample requirement.

3. Plasma-Separator Gel: Gel tubes can improve separation and handling, but the gel may not be appropriate for every assay, therapeutic drug, Toxicology method, or specialized application.

4. Tube material: Plastic and glass tubes may have different handling characteristics, breakage risks, transport requirements, and compatibility considerations.

5. Vacuum and fill tolerance: Underfilling can change the blood-to-additive ratio and may affect results. The manufacturer’s stated fill range should be reviewed, particularly for small-volume tubes.

6. Closure and stopper: The stopper should remain secure during transport and centrifugation. Facilities should also verify that the tube works with their automated labeling and specimen-processing equipment.

7. Expiration and lot traceability: Tubes should arrive with adequate remaining shelf life and identifiable lot information for inventory control, recalls, and quality investigations.

Regulatory and Quality Considerations

In the United States, many blood collection tubes used for clinical testing are regulated as medical devices. The exact regulatory pathway depends on the product and its intended use. A purchaser should ask the manufacturer or distributor for the appropriate regulatory information rather than treating every product in a general laboratory catalog as equivalent.

Clinical laboratories operating under the Clinical Laboratory Improvement Amendments must maintain procedures that support accurate and reliable testing. The Centers for Medicare & Medicaid Services administers CLIA, while accreditation organizations may impose additional requirements. Tube selection, specimen handling, centrifugation, and storage should be addressed in laboratory procedures and verified when a new collection system is introduced.

The Clinical and Laboratory Standards Institute publishes widely used consensus guidance on venous blood collection, order of draw, specimen handling, and quality practices. Although CLSI documents are not a substitute for a laboratory’s own validation and test-specific instructions, they are important references when developing collection procedures.

Occupational safety is also relevant. The Occupational Safety and Health Administration’s bloodborne pathogens standard requires employers to use appropriate controls and work practices to reduce exposure risks. Heparin tubes should be used with compatible safety needles, holders, transfer devices, and sharps containers. Purchasing teams should evaluate the complete collection process rather than selecting tubes independently from the devices used to collect blood.

Verification before clinical use

When a laboratory changes brands or tube types, it should determine whether verification, validation, or correlation studies are needed. The depth of evaluation depends on the test system, regulatory requirements, laboratory policy, and the extent of the change. At a minimum, the laboratory should review manufacturer instructions, compare specimen quality, assess fill performance, verify centrifugation requirements, and investigate any differences in results or rejection rates.

Special attention may be needed for tests involving Therapeutic Drug Monitoring, trace elements, endocrinology, Toxicology, molecular diagnostics, or assays that are sensitive to gel or tube materials. A tube that works well for routine sodium and potassium testing may not be suitable for every analyte.

Pricing and Purchasing Economics

Pricing varies substantially according to brand, tube size, packaging, order quantity, contract status, shipping method, and market conditions. A high-volume hospital may purchase tubes by the case under a negotiated agreement, while a small medical office may pay a higher per-tube price for a smaller box.

Published catalog prices are often not the final price paid by institutional customers. Contract discounts, rebates, freight charges, distributor fees, and minimum-order policies can change the effective cost. In addition, the lowest unit price may not represent the lowest total cost if the product produces more specimen rejections, requires a different holder, or has a shorter shelf life.

Purchasers should calculate total acquisition cost. This can include the tube, compatible needle and holder, shipping, storage space, staff training, waste disposal, inventory carrying costs, and the financial impact of recollected specimens. For a busy laboratory, even a small difference in rejection or recollection rates can outweigh a modest difference in tube price.

Useful purchasing metrics

1. Cost per usable tube: Divide total delivered cost by the number of tubes that meet specifications and remain within acceptable shelf life.

2. Stockout frequency: Track how often the supplier cannot fulfill the requested product on schedule.

3. Specimen Rejection rate: Monitor underfill, clotting, hemolysis, leakage, incorrect tube, and labeling-related problems after a product change.

4. Delivery performance: Compare promised delivery dates with actual receipt dates and document backorders or substitutions.

5. Shelf-life performance: Record the remaining expiration period when products arrive, especially for low-volume facilities.

Managing Supply Continuity

Blood collection tubes are routine consumables, but disruptions can affect the entire diagnostic process. Public health emergencies, transportation problems, manufacturing interruptions, raw-material shortages, recalls, and sudden increases in testing volume can all reduce availability. The Covid-19 pandemic demonstrated how quickly demand for collection supplies could change across the U.S. healthcare system.

A continuity plan should identify the primary supplier, an approved secondary source, acceptable substitute products, minimum stock levels, and the staff responsible for approving changes. Facilities should avoid switching products informally during a shortage. A substitute tube may require changes to order-of-draw procedures, specimen-processing instructions, analyzer settings, or test validation records.

Maintaining excessive inventory is not always the best solution. Tubes have expiration dates, occupy storage space, and may be damaged by heat, freezing, moisture, or rough handling. A more effective approach is often a calculated safety stock based on average daily use, supplier lead time, demand variability, and the time required to qualify an alternate product.

Storage and receiving practices

Manufacturers specify storage conditions for each product. In general, tubes should be kept in a clean, dry environment within the stated temperature range and protected from direct sunlight and physical damage. They should not be stored in a way that causes crushing, excessive vibration, or exposure to chemicals.

At receiving, staff should inspect shipping cartons for damage, confirm the product number, compare the quantity with the purchase order, record lot numbers when required, and check expiration dates. Any evidence of leakage, cracked tubes, loose stoppers, unusual discoloration, or compromised packaging should be documented and reported to the supplier.

Questions to Ask a U.S. Supplier

Before placing a large order, a healthcare organization should obtain clear answers from the manufacturer or distributor. The following questions can help distinguish a suitable product from a merely similar catalog item.

1. Is the product lithium Heparin, sodium Heparin, or another formulation?

2. Does the tube contain a plasma-Separator Gel?

3. What are the nominal draw volume and acceptable fill range?

4. What specimen types and tests are listed in the manufacturer’s instructions?

5. Is the tube intended for clinical diagnostic use, research use, or both?

6. What tube sizes, packaging quantities, and case configurations are available?

7. What is the minimum remaining shelf life at the time of shipment?

8. Can the supplier provide lot traceability and recall notifications?

9. What are the storage and transportation requirements?

10. What is the policy for backorders, substitutions, damaged shipments, and short-dated inventory?

Best Purchasing Options by Facility Type

Large hospitals and integrated health systems often benefit from manufacturer contracts or national distributors. BD, Greiner Bio-One, and SARSTEDT may be evaluated during systemwide standardization projects, while Cardinal Health, McKesson, or Medline may provide consolidated distribution. The most important considerations are supply reliability, interoperability with laboratory automation, contract terms, and clinical verification.

Independent laboratories may prefer direct manufacturer relationships or laboratory distributors such as Fisher Scientific. These facilities typically need detailed technical documentation and consistent lot availability because their workflows can depend on a limited number of validated tube types.

Physician offices, urgent-care centers, and Mobile Phlebotomy services often purchase through broadline distributors or local suppliers. Convenience and smaller order quantities can be important, but these buyers should still verify the exact tube type. A general “green-top” order can result in an unsuitable product if the catalog includes both plain Heparin and gel-separator tubes.

Research laboratories should be especially careful about the distinction between research-use-only products and tubes suitable for clinical diagnostic testing. Research products may be perfectly appropriate for a study protocol but may not meet the requirements of a regulated patient-testing environment.

Practical Buying Checklist

A disciplined purchasing process reduces the risk of ordering the wrong product or creating an avoidable supply problem. Before approving a Heparin tube, the buyer should complete the following sequence.

1. Obtain the laboratory’s written requirement for anticoagulant, tube format, volume, and intended tests.

2. Identify at least two qualified manufacturers or distributors when continuity of supply is important.

3. Compare the manufacturer product number rather than relying on color descriptions.

4. Request technical documentation, instructions for use, storage information, and regulatory details.

5. Confirm compatibility with needles, holders, centrifuges, analyzers, automation, and transport systems.

6. Evaluate sample products when appropriate and have the laboratory review them before a full conversion.

7. Calculate delivered cost, including freight, minimum orders, accessories, and potential recollection costs.

8. Set minimum and maximum inventory levels based on actual consumption and supplier lead time.

9. Document the approved product and establish a formal process for substitutions.

10. Review supplier performance periodically using delivery, quality, expiration, and rejection data.

Conclusion

U.S. buyers can obtain Heparin blood collection tubes from major manufacturers such as BD, Greiner Bio-One, and SARSTEDT, as well as from national distributors including Cardinal Health, McKesson, Medline, and Fisher Scientific. Regional medical-supply companies and specialized laboratory suppliers may provide additional choices, particularly for small practices, research facilities, pediatric services, and point-of-care applications.

The best supplier depends on the facility’s testing menu, volume, contract structure, geographic location, inventory needs, and quality requirements. The purchasing decision should begin with the correct additive and specimen type, not with tube color or price. Lithium-Heparin, sodium-Heparin, plain Heparin, and plasma-separator tubes may have different uses, and products from different manufacturers should not be treated as automatically interchangeable.

By confirming specifications, regulatory documentation, compatibility, shelf life, lot traceability, storage requirements, and delivery performance, U.S. healthcare organizations can select a dependable source while protecting specimen quality and laboratory accuracy. A supplier that provides consistent products, transparent documentation, and responsive shortage support is generally more valuable than one offering the lowest initial unit price.
