Centrifuges Selection for Efficient Separations

By OHAUS INDOCHINA LIMITED

Centrifuges are the basic equipment tool in the laboratory. It use for separates solids-liquids or liquids-liquids base on different specific gravity or density properties of substances. The separation is encouraged by centrifugal force that lets the substances move outward in the radial direction.

Main factors of centrifuge are Speed and g Force, both factors are the basic to be consider before selection and use the centrifuge. Besides, temperature factor had effect to temperature sensitive sample that we can select the refrigerated centrifuge (down to -20 C) model to control chamber temperature during spinning. Rotor type that holds the sample tubes had also important to consider. There are fix angle rotor and swing out rotor that varied size of volume from 1.5ml up to 750 ml or higher. Rotor Type are effect to speed set up limit in centrifuge.

Therefore, centrifuges selection for efficient separations firstly we need to know the volume of sample that we use and max speed for spinning. Secondly, we consider rotor type that can support for both volume and speed and the last step have to look model of centrifuge (can select room temperature centrifuge or refrigerated centrifuge) that support with rotor type, maximum speed and sample. Then we can confident our separation works get the good results.
