Where to Buy Heparin Blood Collection Tubes in the United States: Manufacturers and Suppliers

Summary

• Heparin blood collection tubes are sold in the United States by major manufacturers and distributors, including BD, Greiner Bio-One, Sarstedt, McKesson, Cardinal Health, Medline, Fisher Scientific, and Henry Schein.
• Purchasers should confirm the tube type, Heparin formulation, fill volume, draw size, expiration date, packaging, regulatory status, and compatibility with their laboratory’s analyzers before placing an order.
• Hospitals, physician offices, reference laboratories, and Mobile Phlebotomy services can reduce purchasing problems by standardizing products, monitoring inventory, and buying through qualified medical-supply channels.

Understanding Heparin Tubes in Phlebotomy

Heparin tubes are blood collection tubes used primarily when a laboratory needs plasma rather than serum. The tube contains an anticoagulant, usually lithium Heparin or sodium Heparin, that prevents the collected blood from clotting. After centrifugation, the laboratory can use the plasma layer for many chemistry, electrolyte, immunology, molecular, and specialized testing procedures.

In the United States, Heparin tubes are commonly identified by a green or light-green stopper. However, stopper color alone is not sufficient for purchasing or laboratory verification. Manufacturers may use different shades of green to distinguish a standard Heparin tube from a plasma separator tube, often called a PST. A PST generally contains lithium Heparin and a gel barrier that separates plasma from blood cells after centrifugation.

The correct tube depends on the laboratory’s test menu and analyzer requirements. A lithium-Heparin tube is frequently used for routine plasma chemistry, while sodium-Heparin tubes may be selected for specific tests where lithium contamination could affect results. Some specialized applications require trace-element-free or electrolyte-specific collection materials. Buyers should therefore treat “green-top tube” as a general description rather than a complete product specification.

The U.S. phlebotomy-supplies market is supported by several large original manufacturers, national medical distributors, laboratory-supply companies, regional distributors, and online business-to-business vendors. Availability can change because of manufacturing allocations, recalls, transportation delays, seasonal demand, and health-system purchasing contracts. For that reason, the best supplier is not always the company offering the lowest listed unit price. Product consistency, documented quality, delivery performance, and customer support are equally important.

Major Manufacturers of Heparin Blood Collection Tubes

BD

BD, formerly known as Becton, Dickinson and Company, is one of the most widely recognized manufacturers of evacuated blood collection systems in the United States. Its Vacutainer product family includes lithium-Heparin tubes, sodium-Heparin tubes, and plasma separator tubes in several sizes and configurations.

BD tubes are commonly used by hospitals, outpatient laboratories, physician practices, emergency departments, and large reference laboratories. The company offers tubes with different additives, draw volumes, stopper designs, and label formats. Buyers may encounter standard evacuated tubes, pediatric or small-volume products, and tubes designed for chemistry or specialized laboratory applications.

BD products are often available through hospital group purchasing contracts and national distributors. They are also commonly listed by laboratory-supply companies serving smaller clinics. When requesting a quote, purchasers should provide the exact catalog number, tube dimensions, additive, fill volume, and packaging unit because several products may appear similar in a distributor’s search results.

Greiner Bio-One

Greiner Bio-One manufactures the VACUETTE blood collection system, which is distributed throughout the United States. Its product range includes lithium-Heparin tubes, sodium-Heparin tubes, and gel-containing plasma separator tubes. Greiner’s tubes are used in hospitals, independent laboratories, physician offices, and research facilities.

Greiner Bio-One is a significant competitor in the U.S. specimen-collection market. Its products may be especially attractive to organizations seeking an alternative to BD or attempting to standardize a second source. Before changing brands, a laboratory should conduct a validation or verification process based on its quality-management procedures. Tube material, additive concentration, gel behavior, draw volume, centrifugation instructions, and analyzer performance can vary between manufacturers.

Greiner products are available from laboratory distributors and national medical-supply companies. Some buyers purchase directly through a regional sales representative, while others use a distributor already approved by their health system or group purchasing organization.

Sarstedt

Sarstedt supplies blood collection and specimen-management products in the United States, including tubes containing lithium Heparin and other anticoagulants. Its products are used in clinical laboratories, hospitals, research institutions, and specialty testing environments.

Sarstedt offers a broad range of collection systems, including products intended for routine venous draws, pediatric collections, and specialized laboratory workflows. Depending on the product, the tube may be made for plasma preparation, direct testing, or use with a particular specimen-processing method.

Customers purchasing Sarstedt Heparin tubes should verify whether their existing tube racks, centrifuges, pneumatic-tube system, automated processing line, and analyzer interfaces are compatible. A change in tube dimensions or label placement can create operational problems even when the additive and nominal volume appear equivalent.

Other Specialty and Regional Manufacturers

In addition to the largest brands, the U.S. market includes smaller manufacturers, private-label suppliers, and international companies represented by domestic distributors. These sources may sell Heparin tubes for routine chemistry, blood-gas sampling, molecular testing, trace-element work, or research use.

Smaller or private-label products can be appropriate when the supplier provides adequate documentation and the laboratory has completed the required evaluation. Buyers should request product specifications, certificates of analysis when applicable, instructions for use, lot information, storage requirements, and evidence that the product is appropriate for the intended diagnostic application.

U.S. Medical and Laboratory Distributors That Sell Heparin Tubes

McKesson

McKesson is one of the largest healthcare distributors in the United States. Its medical-supply business serves hospitals, physician offices, clinics, laboratories, pharmacies, and other healthcare organizations. McKesson commonly offers blood collection tubes from major manufacturers, including products with lithium Heparin, sodium Heparin, and plasma-separator configurations.

McKesson customers may benefit from consolidated purchasing because the company distributes many other phlebotomy products, such as needles, holders, tourniquets, alcohol wipes, gauze, labels, sharps containers, and specimen bags. A facility may be able to reduce freight charges and simplify invoicing by purchasing several categories of supplies through one approved account.

Availability and pricing can depend on customer contracts, regional distribution centers, account size, and manufacturer allocations. Buyers should ask whether the product is regularly stocked or shipped directly from a manufacturer, and whether substitutions are permitted when the specified catalog number is unavailable.

Cardinal Health

Cardinal Health distributes medical and laboratory products to hospitals, ambulatory surgery centers, physician practices, laboratories, and other healthcare organizations. Its catalog may include Heparin tubes from leading manufacturers as well as associated collection and processing supplies.

Cardinal Health can be useful for organizations that already have a purchasing agreement or an established logistics relationship with the company. Large health systems may also use contracted pricing, electronic ordering, inventory-management programs, and scheduled deliveries. These services can be important because the cost of a blood collection tube is only one component of the total purchasing expense.

When ordering through a national distributor, the laboratory should review the actual manufacturer and catalog number on the shipment. A distributor’s website may group similar tube types under a broad description, while the delivered product may differ in additive, volume, or gel configuration if substitution rules are not controlled.

Medline

Medline is a major U.S. medical-supply manufacturer and distributor with products used in hospitals, long-term-care facilities, outpatient clinics, laboratories, and physician practices. Medline’s phlebotomy and specimen-collection offerings may include Heparin tubes and complementary supplies.

Medline is often considered by clinics that want a broad medical-supply source rather than a laboratory-only supplier. Buyers can potentially combine tube purchases with exam gloves, gowns, disinfectants, sharps containers, specimen transport bags, and other routine products. This approach can simplify procurement, although laboratories should verify that the specific tube is intended for in vitro diagnostic use and is accepted by the testing laboratory.

Fisher Scientific

Fisher Scientific serves clinical laboratories, hospitals, universities, biotechnology companies, pharmaceutical organizations, and research institutions. Its U.S. catalog commonly includes blood collection tubes from BD, Greiner Bio-One, Sarstedt, and other manufacturers.

Fisher Scientific is particularly useful for laboratories that purchase both clinical and research supplies. The company’s catalog structure may allow customers to compare tube sizes, additives, sterile and nonsterile configurations, packaging quantities, and manufacturer specifications. However, a research-use-only product should not be substituted for a clinical diagnostic collection tube without confirming its intended use and regulatory status.

Because laboratory catalogs can contain many visually similar products, purchasers should search by the exact manufacturer part number whenever possible. Searching only for “green-top tube” may return lithium-Heparin tubes, sodium-Heparin tubes, PST tubes, Microcollection Tubes, and products intended for nonclinical research.

Henry Schein

Henry Schein distributes healthcare products to physician offices, dental practices, clinics, and other Healthcare Providers. Its medical catalog may include blood collection tubes and general phlebotomy supplies, making it a possible source for smaller practices that do not purchase directly from large laboratory manufacturers.

Independent physician offices may find a distributor such as Henry Schein convenient when they already use the company for gloves, syringes, dressings, disinfectants, and other clinical products. Before ordering, the practice should confirm that the tube size matches its laboratory’s requirements and that the product is not intended only for research or veterinary use.

Regional Laboratory and Medical-Supply Distributors

Many U.S. buyers obtain Heparin tubes from regional distributors. These companies may serve a particular state, metropolitan area, hospital network, or laboratory association. Regional vendors can sometimes provide faster delivery, lower minimum order quantities, and more personalized customer service than national distributors.

A regional supplier may also be able to provide emergency deliveries during a shortage. However, buyers should evaluate the vendor’s quality controls, storage practices, product-traceability procedures, return policy, and ability to maintain a consistent lot supply. A low price is not beneficial if a clinic receives expired, improperly stored, or incorrectly substituted products.

Types of Heparin Tubes Available in the United States

Lithium-Heparin Tubes

Lithium-Heparin tubes are widely used for plasma chemistry testing. The Anticoagulant prevents clot formation while generally avoiding the sodium contribution associated with sodium-Heparin tubes. They are often selected for electrolyte, metabolic, enzyme, and other chemistry applications, subject to the laboratory’s validated procedures.

Lithium-Heparin tubes may be available in several volumes, including common adult sizes and smaller tubes for pediatric or difficult draws. Some have a plain green stopper, while others contain a gel separator. The product description should state the Heparin type and whether a gel barrier is present.

Sodium-Heparin Tubes

Sodium-Heparin tubes contain sodium Heparin and may be used for selected chemistry, special chemistry, cytogenetic, or other applications. They should not automatically be treated as interchangeable with lithium-Heparin tubes. The sodium component may affect certain Test Results, and the laboratory’s procedure may specify one formulation over the other.

Some sodium-Heparin tubes are also used for blood-gas or specialized testing, although blood-gas collection often involves dedicated syringes or capillary devices. Buyers should follow the laboratory’s specimen requirements rather than selecting a tube solely because it contains Heparin.

Plasma Separator Tubes

Plasma separator tubes contain Heparin and a polymer gel. After centrifugation, the gel forms a barrier between the plasma and cellular components. PSTs can support efficient specimen processing, particularly in laboratories using automated chemistry systems.

The gel can influence certain specialized tests, and not every assay is validated for every separator-tube brand. Laboratories should review their test directory before replacing a plain Heparin tube with a PST or changing from one PST manufacturer to another.

Trace-Element and Specialty Tubes

Specialty Heparin tubes may be manufactured with low-contamination materials or specific controls for trace-element testing. These products are usually more expensive than routine chemistry tubes and may have different handling requirements.

Specialty tubes should be purchased only after confirming the laboratory’s exact requirements. A routine lithium-Heparin tube may not be suitable for trace metals, Toxicology, blood-gas testing, cell studies, or molecular assays. The laboratory should identify the required additive, material, volume, stopper type, transport temperature, and processing timeline before purchasing.

How to Compare U.S. Suppliers

Price comparisons should be based on cost per usable tube rather than the advertised package price. A box containing 100 tubes may not be the best value if the facility has high discard rates, frequent back orders, or excessive shipping costs. Buyers should compare the complete landed cost, including freight, handling, minimum-order requirements, storage losses, and emergency purchases.

1. Confirm the exact product. Record the manufacturer, catalog number, tube type, additive, nominal draw volume, tube dimensions, stopper color, and gel configuration.
2. Compare packaging. Determine whether the supplier sells individual tubes, boxes, cases, or mixed-case quantities. Check the number of tubes per box and case.
3. Review expiration dating. Ask whether the distributor can provide a minimum remaining shelf life at delivery, especially when purchasing large quantities.
4. Evaluate availability. Review historical fill rates, estimated lead times, back-order procedures, and the supplier’s substitution policy.
5. Check storage and transport. Confirm that products are stored and shipped according to the manufacturer’s instructions.
6. Verify returns and recalls. Understand how the supplier handles damaged cartons, incorrect products, lot complaints, and manufacturer recalls.
7. Calculate total cost. Include shipping, minimum-order thresholds, contract pricing, taxes where applicable, and the labor cost of managing multiple vendors.

Some healthcare organizations use a primary supplier and a qualified secondary supplier. This strategy can reduce dependence on one distribution channel during shortages. A secondary supplier should not be activated casually, however. The replacement tube may require laboratory verification, revised procedures, staff education, or changes to analyzer programming.

Regulatory and Quality Considerations

Blood collection tubes used for patient testing are generally medical devices and may be subject to U.S. Food and Drug Administration requirements. Buyers should confirm that the product is marketed for the intended diagnostic use and that the supplier can provide appropriate labeling and instructions for use. A product listed for research use only may not be appropriate for routine patient specimens.

Clinical laboratories operating under the Clinical Laboratory Improvement Amendments must maintain procedures for specimen collection, handling, processing, and testing. The Centers for Medicare and Medicaid Services, through CLIA, emphasizes the importance of appropriate Specimen Integrity and validated laboratory procedures. A tube change can affect preanalytical quality and may need to be documented under the laboratory’s change-control process.

The Clinical and Laboratory Standards Institute publishes guidance commonly used by laboratories for venous blood collection, order of draw, specimen handling, and tube selection. Laboratories may also follow accreditation requirements from organizations such as The Joint Commission, the College of American Pathologists, or other applicable accrediting bodies.

Purchasing departments should work with the laboratory director, quality manager, infection-prevention staff, and phlebotomy leadership before approving a new Heparin tube. The procurement decision should consider not only the product specification but also the effect on patient identification, specimen labeling, centrifugation, transport, and test performance.

Inventory Planning and Demand Forecasting

Heparin tubes are disposable supplies, and demand is closely related to patient volume, test mix, collection method, and discard rates. A hospital emergency department may use more plasma tubes than a primary-care practice because of higher testing volume and greater demand for rapid chemistry results. A specialty clinic may use relatively few tubes but require uncommon sizes or formulations.

A basic inventory system should track average weekly use, maximum weekly use, supplier lead time, minimum stock level, expiration dates, and open purchase orders. Organizations should also measure the number of tubes discarded because of short draws, contamination, broken tubes, incorrect additive, expired stock, or improper storage.

Healthcare supply-chain disruptions have demonstrated the importance of safety stock. The Covid-19 pandemic produced significant stress across medical supply chains, including shortages and allocation concerns involving collection materials. Although conditions vary by year and product, the experience reinforced the need for dual sourcing, realistic reorder points, and communication with suppliers.

Purchasers should avoid excessive stockpiling. Over-ordering can create expired inventory, tie up working capital, and reduce warehouse space. A practical approach is to maintain enough stock to cover normal demand plus a defined contingency period based on historical supplier performance.

Preventing Common Purchasing Errors

One of the most common errors is ordering by stopper color without verifying the additive. Green-top tubes may contain lithium Heparin, sodium Heparin, or Heparin with gel. They may also be available in different sizes and draw volumes. The buyer should always compare the catalog number and product description with the laboratory’s approved supply list.

Another error is confusing plasma separator tubes with serum separator tubes. Both may contain gel, but they use different clotting or Anticoagulant systems. A serum separator tube is generally not an interchangeable substitute for a lithium-Heparin PST.

Short draws can also create problems. If the tube is not filled to the manufacturer’s intended volume, the blood-to-additive ratio may be incorrect. Although the effect varies by test and tube design, underfilling can compromise specimen quality. Buyers should ensure that the ordered tube is appropriate for the collection volume available from the patient population.

Purchasers should also be cautious about tubes with nearly identical packaging. Different tube dimensions, wall materials, gel formulations, and stopper designs may affect automated systems. A sample may fit a centrifuge but fail to work correctly in an analyzer, aliquoter, or pneumatic-tube carrier system.

Questions to Ask a Potential Supplier

1. Which manufacturer and catalog number will be supplied?
2. Does the tube contain lithium Heparin, sodium Heparin, or another Heparin formulation?
3. Does the tube include a gel separator?
4. What are the nominal draw volume and tube dimensions?
5. What is the minimum remaining shelf life at the time of shipment?
6. Is the product routinely stocked in the United States?
7. What is the standard lead time, and how are back orders communicated?
8. Are substitutions allowed without prior written approval?
9. Can the supplier provide lot traceability and recall notifications?
10. What are the shipping, storage, return, and damaged-product policies?
11. Is the product intended for clinical diagnostic use, research use, or another application?
12. Can the supplier support recurring orders or inventory-management services?

These questions are particularly important for smaller practices that may not have a dedicated laboratory procurement team. A reputable supplier should be able to identify the product clearly and explain whether it is supplied directly by the manufacturer, held in a domestic distribution center, or obtained through a third-party channel.

Choosing the Best Supplier for Different U.S. Buyers

Hospitals and Integrated Health Systems

Hospitals often benefit from contracted purchasing through McKesson, Cardinal Health, Medline, or a group purchasing organization. The primary concern is usually product standardization across departments. A hospital may select one approved Heparin tube for emergency, inpatient, outpatient, and laboratory departments to reduce errors and simplify training.

Large systems should also maintain a qualified alternative product. Any alternative should undergo laboratory evaluation before a shortage occurs. Contract terms should address allocation, delivery performance, substitutions, recalls, and emergency orders.

Physician Offices and Outpatient Clinics

Physician offices may purchase through Henry Schein, Medline, McKesson, local distributors, or a laboratory service that supplies collection materials. These facilities should focus on manageable case quantities, expiration dating, simple reordering, and compatibility with the reference laboratory receiving the specimens.

If specimens are sent to an outside laboratory, the clinic should obtain that laboratory’s approved collection-tube list. The receiving laboratory may reject specimens collected in an unapproved tube even when the stopper color appears correct.

Independent and Reference Laboratories

Independent laboratories generally need detailed product control, lot tracking, and reliable supply continuity. Fisher Scientific, direct manufacturer arrangements, and national laboratory distributors may be suitable options. These laboratories should compare tube performance across analyzers and maintain documented verification records for any new product.

Mobile Phlebotomy Services

Mobile Phlebotomy providers should consider tube durability, portability, packaging, temperature exposure, and transport time. Smaller case quantities may reduce waste, but the supplier must still provide sufficient shelf life. Mobile teams should use secure specimen containers and follow the receiving laboratory’s requirements for plasma processing and transport.

Final Purchasing Guidance

U.S. buyers can obtain Heparin tubes from major manufacturers such as BD, Greiner Bio-One, and Sarstedt, as well as from distributors including McKesson, Cardinal Health, Medline, Fisher Scientific, Henry Schein, and regional medical-supply companies. The appropriate source depends on the buyer’s location, contract arrangements, testing volume, required tube type, delivery schedule, and quality expectations.

The most important purchasing step is to identify the exact tube required by the laboratory. Buyers should specify the Heparin formulation, gel status, volume, dimensions, intended test category, and manufacturer part number. They should then compare suppliers using total cost, availability, expiration dating, documentation, and customer-service performance rather than unit price alone.

Because Heparin tubes directly affect specimen quality, a purchasing change should involve the laboratory and quality team. Confirming regulatory status, reviewing instructions for use, validating compatibility, and controlling substitutions can prevent rejected specimens and inaccurate results. With standardized specifications and dependable inventory practices, U.S. healthcare organizations can purchase Heparin tubes efficiently while maintaining reliable phlebotomy and laboratory operations.
