Centrifugal evaporator

A centrifugal evaporator is a device used in chemical and biochemical laboratories for the efficient and gentle evaporation of solvents from many samples at the same time, and samples contained in microtitre plates.

Patent US158764 was granted in 1875 to Conrad Wendel and William Florich for an improvement in centrifugal evaporators.

[citation needed] There are many further developments available from manufacturers to speed up the process, and to provide protection for delicate samples.

This enables solvent to be rapidly removed while the samples themselves are not heated to damaging temperatures.

The centrifugal force generated by spinning the centrifuge rotor creates a pressure gradient within the solvent contained in the tubes or vials, this means that the samples boil from the top down, helping to prevent "bumping".
