1.0 mL Conical Microcentrifuge Tubes with Snap Cap — Polystyrene, Natural, 1000/Bag
These 1.0 mL conical microcentrifuge tubes are manufactured from virgin-grade polypropylene polystyrene (PS) for excellent optical clarity and low protein binding, making them well suited to serum, plasma, and other microvolume workflows. Supplied non-sterile in sealed 1000/Bag packaging, part number 214-3710-010 features a conical bottom that concentrates pellets at the tip for complete sample recovery with minimal dead volume. Lot-to-lot dimensional consistency ensures reliable fit across standard microcentrifuge rotor positions.

Frequently Asked Questions
Are these microcentrifuge tubes sterile?
No — they are supplied non-sterile. For most molecular biology, clinical chemistry, and sample-storage applications this is appropriate; if your protocol requires sterile tubes, please contact us for sterile alternatives.
Why is polystyrene used instead of polypropylene for these tubes?
Polystyrene offers superior optical clarity for visual inspection of sample color and pellet formation, along with low protein-binding characteristics that benefit serum and plasma workflows. If your protocol involves acetone, chlorinated solvents, or autoclaving, polypropylene tubes would be the better choice, as PS is not autoclavable and has limited solvent resistance.
Are the tubes suitable for high-speed microcentrifugation?
The conical PS construction provides rigid wall performance during standard benchtop centrifugation. Always verify the maximum RCF rating for your specific rotor and confirm compatibility with your centrifuge manufacturer's guidelines before running at high speeds.
Does each bag include lot and date information for regulatory traceability?
Yes — every 1000/Bag is lot-numbered and date-coded at the time of manufacture, supporting documentation requirements for CAP-accredited, CLIA-certified, and ISO 15189 laboratories.
