Frequently Asked Questions

Are these test tubes sterile?
No — part number 214-2367-B30 is supplied non-sterile. For most clinical chemistry, hematology, and general laboratory applications, sterility is not required; however, if your protocol demands sterile tubes, please contact us for sterile alternatives.

Will these tubes fit standard autoanalyzer sample racks?
Yes. The 12 × 75 mm outer dimensions are consistent with standard 12 mm autoanalyzer rack positions used across common clinical chemistry platforms. Lot-to-lot dimensional tolerances are controlled to ensure reliable rack fit.

Are the tubes compatible with serum and plasma samples?
Yes. Virgin-grade polypropylene is inert toward aqueous biological matrices including serum, plasma, whole blood, and urine, and the resin meets FDA 21 CFR Part 177 requirements for food- and specimen-contact applications.

Do these tubes support CAP and CLIA traceability requirements?
Yes. Each bag is lot-numbered and date-coded, providing the documentation chain needed for CAP, CLIA, and ISO 15189 laboratory accreditation audits.
