Basics in Centrifugation - Eppendorf Handling Solutions

Basics in Centrifugation. Centrifugation is a technique that helps to separate mixtures by applying centrifugal force. A centrifuge is a device, generally driven by an electric motor, that puts an object, e.g., a rotor, in a rotational movement around a fixed axis. A centrifuge works by using the principle of sedimentation: Under the influence

Centrifuge Safety - Eppendorf Handling Solutions

Wipe the outside of the tube with disinfectant before placing it in the centrifuge. Wiping the tube is particularly important if you are working with a biohazardous material. You want to limit any possible spills or aerosol formation with your sample. The best prevention is to wipe down the tube with a proper disinfectant before the spin begins.

What Is Balancing A Centrifuge And Why Is It Important

2021-12-12 · When there is an even nuer of samples, the centrifuge can be balanced by dividing the total nuer of tubes in half and placing the two sets into the rotor directly opposite each other to create an equal nuer of tubes on each side. Aerosols can be created when a centrifuge tube or sample tube breaks inside of the rotor.
