Centrifuge - Wikipedia

Centrifuge - Wikipedia

A centrifuge is a device that uses centrifugal force to separate various components of a fluid. This is achieved by spinning the fluid at high speed within a container, thereby separating fluids of different densities (e.g. cream from milk) or liquids from solids. It works by causing denser substances and particles to move outward in the radial direction.

Centrifugation - Wikipedia

Centrifugation is a mechanical process which involves the use of the centrifugal force to separate particles from a solution according to their size, shape, density, medium viscosity and rotor speed. The denser components of the mixture migrate away from the axis of the centrifuge, while the less dense components of the mixture migrate towards the axis.

Dec 18, 2014 Carefully aspirate the supernatant leaving the pellet behind. Re-suspend the pellet in an appropriate volume of flow buffer, depending on the size of the pellet (e.g., for one confluent T75 flask of SH-SY5Y cells the typical yield is at least 10 x 10 6 cells, in which case the cells are resuspended in 5 ml of flow buffer). NOTE: If larger ...

Iso-density (Isopyncic) Centrifugation (AB3.4.3) Molecules separated on equilibrium position, NOT by rates of sedimentation. After centrifugation, each molecule floats or sinks (=re-distribution) to position where density equals density of CsC (or sucrose)l solution. Then no net sedimenting force on

Jun 23, 2015 Differential centrifugation is a common procedure in microbiology and cytology used to separate certain organelles from whole cells for further analysis of specific parts of cells. In the process, a tissue sample is first homogenized to break the cell membranes and mix up the cell contents. The homogenate is then subjected to repeated ...
