0.5 mL Conical Microcentrifuge Tubes with Snap Cap — Polypropylene, Natural, 1000/Bag
These 0.5 mL conical microcentrifuge tubes are molded from virgin-grade polypropylene (PP) and sealed in 1000/Bag packaging for high-throughput labs that demand lot-to-lot dimensional consistency. The conical bottom geometry concentrates pellets at the tube tip, enabling complete microvolume recovery with minimal dead volume — a critical advantage in DNA/RNA extraction, enzyme reactions, and protein precipitation workflows. Supplied non-sterile, part number 214-3703-030 is BPA-free, phthalate-free, and manufactured to ISO-certified dimensional standards that ensure a reliable fit in standard microcentrifuge rotor positions.

Quality & Procurement
Made in USA, these Caplugs® Evergreen microcentrifuge tubes are produced from virgin-grade polypropylene under ISO-certified quality management, meeting FDA 21 CFR Part 177 standards and confirmed free of BPA, phthalates, and latex. Every bag carries a lot number and manufacturing date, supporting full CAP, CLIA, and ISO 15189 traceability for accredited clinical and research laboratories. LabSupplies.com is an authorized Caplugs® Evergreen dealer shipping from USA inventory, which eliminates the offshore lead-time risk that can disrupt high-throughput processing schedules. Tiered pricing is available for institutional procurement and grant-funded purchasing programs.
Frequently Asked Questions
Are these microcentrifuge tubes sterile?
No — they are supplied non-sterile in 1000/Bag packaging. For most molecular biology, clinical chemistry, and sample preparation workflows, non-sterile tubes are standard; if sterility is required for your application, please contact us for alternative options.
Are these tubes BPA-free and phthalate-free?
Yes. The tubes are molded from virgin-grade polypropylene that is confirmed BPA-free and phthalate-free, meeting FDA 21 CFR Part 177 standards — important for sensitive downstream assays and regulated clinical environments.
Will these tubes fit standard microcentrifuge rotors?
The 0.5 mL conical format is dimensionally consistent with standard microcentrifuge rotor positions. ISO-certified manufacturing controls wall thickness and outer diameter lot-to-lot, so labs can switch from their current supplier without re-qualifying rotor fit.
Does each bag include lot and date information for regulatory traceability?
Yes. Every bag of 214-3703-030 is lot-numbered and date-coded at the point of manufacture, providing the chain-of-custody documentation required for CAP, CLIA, and ISO 15189 laboratory accreditation audits.
