5.0 mL Round Bottom Test Tubes, 12 × 75 mm — Polypropylene, Red, 1000/Bag (214-2367-R30)
These 5.0 mL round bottom test tubes measure 12 × 75 mm and are molded from virgin-grade red polypropylene (PP), supplied non-sterile in sealed 1000/Bag packaging for high-throughput clinical and research workflows. The 12 × 75 mm format seats reliably in standard 12 mm autoanalyzer sample racks, making part number 214-2367-R30 a practical choice for clinical chemistry, hematology sample preparation, and routine laboratory sample handling. Round bottom geometry promotes complete sample drainage and minimizes dead volume, reducing reagent waste and improving result consistency.

Frequently Asked Questions
Are these test tubes sterile?
No — they are supplied non-sterile in sealed 1000/Bag packaging. For most clinical chemistry, hematology, and general sample-handling workflows, sterility is not required; consult your laboratory SOP if sterile consumables are specified.
Will these tubes fit standard autoanalyzer sample racks?
Yes. The 12 × 75 mm outer dimensions are compatible with 12 mm autoanalyzer sample rack positions. Dimensional consistency is maintained lot-to-lot, so tubes seat reliably without manual adjustment.
Are the tubes suitable for contact with serum, plasma, and urine?
Yes. The virgin-grade polypropylene resin meets FDA 21 CFR Part 177 standards and is BPA-free and phthalate-free, making it appropriate for direct contact with serum, plasma, urine, and standard aqueous clinical reagent matrices.
Do the bags carry lot and date information for regulatory traceability?
Yes. Every 1000/Bag unit is lot-numbered and date-coded, providing the documentation chain required for CAP, CLIA, and ISO 15189 accredited laboratory environments.
