Frequently Asked Questions
Are these centrifuge tubes sterile?
No. These tubes ship non-sterile and are intended for applications that do not require pre-sterilized labware. Verify your protocol's sterility requirements before use.
What material are the tubes made from?
The vessels are molded from polystyrene (PS), which provides good optical clarity for visual inspection of pellets and sample volumes. Confirm reagent compatibility with PS for your specific chemistry.
Do the tubes include caps?
The tubes feature a threaded conical design with a screw-style neck. Confirm closure inclusion and thread compatibility against your existing caps before ordering at volume.
How are the tubes packaged?
They are supplied 1000 tubes per bag. Each bag carries lot numbers to support traceability in accredited laboratory environments.
