Frequently Asked Questions
Are these centrifuge tubes sterile?
No. These are non-sterile tubes intended for general laboratory use. For applications requiring sterility, autoclave compatibility depends on your validated cycle, or select a separately offered sterile variant.
Do the tubes include caps?
No. These are unthreaded tubes supplied without caps. They accept compatible plug-style or push closures, so confirm your preferred closure separately before ordering.
What is the maximum recommended centrifugation force?
Rated g-force depends on rotor type, fill volume, and tube support. Always run within your rotor manufacturer's published limits and use properly fitted adapters for 15 mL conical formats.
What does the 1000/Bag pack contain?
Each pack contains 1000 tubes supplied in one bag, with lot numbers for traceability. This bulk format suits high-volume clinical and research labs needing consistent unit pricing.
