Features of Bio Plas Screw Cap for Bio Plas Screw Cap Microcentriufge Tubes:
The extraordinary strength, safety and reliability of our Screw-Cap tube lets you perform procedures that simply can’t
be done with other tubes. Spin it, store it, transport it (even by air). Boil it, irradiate it, immerse it in the vapor phase of liquid
nitrogen-it’ll stand up to the test! Inside the screw cap, our ethylene propylene O-Ring forms
a secure and leakproof seal. Our screw cap’s square threads won’t strip-and they’re on the outside of the tube, so you
minimize the risk of contaminating your sample-or letting it contaminate you.
Eligible for FREE or discounted ground shipping.
