Frequently Asked Questions
Are these centrifuge tubes sterile?
No. These tubes are non-sterile, making them well suited for general sample prep, aliquoting, and storage where sterility is not required. For applications needing sterility, the tubes can be processed according to your validated lab protocols.
Do the tubes ship with caps attached?
The tubes ship unassembled, with green screw caps packaged alongside the tubes rather than pre-installed. This format supports flexible handling and efficient bulk storage of 1000 units per bag.
What is the maximum recommended centrifugation speed?
Recommended RCF limits depend on rotor geometry and your validated method. Polypropylene copolymer offers good mechanical strength for routine clinical and research spins; always confirm limits against your centrifuge and rotor specifications.
What material are these tubes made from?
The tubes are molded from polypropylene copolymer (PPC) in a natural translucent finish, paired with green screw caps. PPC provides robust impact resistance and clarity for visual sample inspection.
