How It Is Used
Samples are spun in a laboratory centrifuge so that denser material collects at the bottom; in the conical type the pellet gathers in the tip and the liquid above can be drawn off with a Pasteur pipette. Check every tube for fine cracks before use, balance opposite tubes by mass to within 0.1 g, and use rubber adapters in the rotor to support the glass.
Frequently Asked Questions
What should be checked before using the Glass Centrifuge Tube?
Inspect each tube for micro-cracks or star-cracks, since a cracked tube can fail at high speed, and balance tubes placed opposite each other to within 0.1 g.
