If this is a laboratory at a dairy plant, then the centrifuge is used to determine fat according to Gerber (acid method) GOST 5867.
As an example, we can cite the OKA milk centrifuge or the TsLM-1-12 centrifuge ".
The essence of the method lies in the fact that, as a result of the action of sulfuric acid, the casein-calcium complex of milk passes a double soluble compound of casein with sulfuric acid.
As a result of the addition of isoamyl alcohol, the surface tension decreases fat globules, the protein coat is removed from the surface of the fat globules. The reaction is accelerated by heating and centrifugation. After centrifugation, fat is released as a continuous transparent layer on the scale of the fatometer and its volume is measured in the graduated part of the fatometer (butyrometer).
That's right, in our laboratory they mix drugs on it, conduct experiments. Recently bought a new powerful spam centrifuge so interesting to work on it.
Medical laboratory centrifuges are designed to separate liquids and solid fractions, particles of greater and lesser severity, liquids with different specific gravity, suspensions. The device is based on spam Centrifuges using the centrifugal force that occurs during rotation. Substances, liquids and mixtures are separated into their components.
