Our Screw-Cap Microcentrifuge Tube is ideal for any sample-processing or storage application imaginable-and especially for working with valuable or hazardous cells and materials. The extraordinary strength, safety and reliability of the Screw-Cap Microcentrifuge 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!
