Frequently Asked Questions
Are these centrifuge bottles autoclavable?
Yes. The PPCO construction withstands repeated autoclaving at 121°C, allowing reuse across multiple separation runs when caps are loosened during sterilization.
What maximum centrifugal force do they support?
PPCO bottles are rated for high-speed use; observe your rotor manufacturer's RCF limits for the bottle size and confirm proper trunnion or adapter support before spinning at maximum speed.
Do the sealing caps prevent leaks during a run?
The screw sealing cap is designed for leak-resistant performance with aqueous samples. For aerosol containment of hazardous material, confirm your rotor and bottle pairing meets your biosafety protocol.
How many bottles are in each pack?
Both the 250 mL (SKU 6330) and 500 mL (SKU 6332) listings are sold by the case of 4 bottles, each with a matching sealing cap.
