Laboratory Tubes & Accessories Buying Guide
Review Additives and Draw Volumes for Blood Collection Tubes
When buying blood collection tubes, the tube to be used depends on the specimen required and the test to be carried out.
For example, BD identifies EDTA tubes for haematology, heparin tubes for some plasma chemistry tests and sodium citrate tubes for routine coagulation studies. Laboratory to confirm the specific tube for each test.
The cap colour can assist identification of a product but should not replace checking the label, additive and manufacturer’s instructions.
Distinguish between tube volume and requested blood volume. The amount of fill is important, as it influences the blood-to-additive ratio, particularly in citrate tubes used for coagulation testing.
Before ordering, please verify the additive, draw volume, tube dimensions, expiry date and compatibility with your collection system and laboratory workflow. Substitutions are to be discussed with the laboratory team before purchase.
Compare Centrifuge Tubes by More Than Size
Searching for 15 mL or 50 mL centrifuge tubes yields a number of similar-looking options. Capacity does not alone determine whether a tube is suitable.
Determine the maximum relative centrifugal force, often written as RCF or ×g. RPM is the speed of rotation, and it is not the same force for rotors of different sizes.
The performance of the tube depends on rotor, adapter, temperature, run time and sample properties. Eppendorf’s instructions for describing centrifugation stability, in particular, emphasise these factors.
Understand Claims of Materials, Sterility and Purity
Laboratory consumables are available in a variety of materials and purity grades. The best specification depends on the application. Don't just assume one is better.
Molecular testing may require a documented nuclease-free or other application-specific purity statement. Sterility and freedom from certain contaminants are separate specifications.
Eppendorf offers different grades of tube purity and formats for specific applications, so buyers should verify the exact product documentation.
Check also if the product can be frozen or heated or autoclaved. Do not use the temperature limits of one manufacturer for another product.
Ensure that the approved storage conditions are clearly identified for cryogenic vials, including whether the intended system involves mechanical freezing or liquid-nitrogen storage.
Right Lab Accessories
Compatible accessories are still required for handling, identification and storage of suitable tubes.
Tube racks should be compatible with the tube diameter and format. Check its stability, its cleaning requirements and its suitability for the environment in which it will be used.
The centrifuge adapters must be valid for the respective tube and rotor combination. A loose fit of a tube in a rotor does not provide sufficient evidence of compatibility.
Caps and closures must match the exact tube style. Do not interchange closures that look similar without checking with the manufacturer.
Labels shall be large enough to contain the required information and shall be legible under storage and handling conditions. Testing barcode readability when using scanners.
Storage boxes and transport accessories should be suitable for the tube dimensions and the handling procedures of the laboratory. Please confirm any containment and temperature control requirements with the responsible team.
Buying tubes and accessories at the same time can help expose any compatibility gaps before the order arrives.

Final Remarks
Selecting laboratory tubes is more than just matching a size or colour. Every purchase should be guided by the intended test, sample, equipment and operating conditions.
Evaluate the price after you build an approved product list and check accessories. Compare equivalent specs. These habits help to make repeat ordering more consistent and help to reduce unsuitable substitutions, wasted stock and avoidable delays.
