Question

Centrifugal concentrator

Answer 1

These are the filters used to seperate solid from liquid phrase by centrifugal force.

Answer 2

Centrifugal concentrators are filtration devices that operate under centrifugal force to separate solids from liquid phase, reducing the final volume. Concentrators are found in many laboratories including organic chemistry, forensic and drug discovery labs. Applications for use include protein extraction and purification, DNA concentration, buffer exchange, and deproteinization. Some factors to consider when purchasing a concentrator are membrane pore size and material, rotor compatibility (fixed, swinging, universal), range of molecular weight cutoff, sample volume range, centrifuge tube size, and concentration factor. With a wide variety of concentrators to choose from, some features to help determine choice include percentage of retentate recovery, short spin times, reproducible performance, and the possibility of re-spinning.
