Frequently Asked Questions
Are these test tubes sterile?
No. These tubes ship non-sterile and are intended for general laboratory use. For applications requiring sterility, validate an in-house sterilization protocol compatible with polystyrene before use.

What are the exact dimensions and capacity?
Each tube measures 17 x 100 mm with a 16 mL nominal capacity and a round bottom profile, fitting standard 17 mm tube racks and many common bench-top holders.
