A laboratory centrifuge is a piece of laboratory equipment, driven by a motor, which spins liquid samples at high speed. There are two main sizes for laboratory centrifuges. The larger ones are known simply as centrifuges; samples are contained in centrifuge tips or centrifuge tubes.The smaller centrifuges are known as microcentrifuges or microfuges, and microcentrifuge tubes …

Methods for Separating Mixtures Chemistry for Non-Majors

Filtration. Filtration is a separation method used to separate out pure substances in mixtures comprised of particles some of which are large enough in size to be captured with a porous material.Particle size can vary considerably, given the type of mixture. For instance, stream water is a mixture that contains naturally occurring biological organisms like bacteria, viruses, and …

Our decanter centrifuges separate fine solids from a suspension and optimally clarify the separated liquid. The Simp Drive concept and the adjustable impeller make it possible to adjust the residence time of the mixture in the decanter bowl during operation. If the conditions at the inlet change, the separation result and solids content in the discharge always remain constant.

The instantaneous sedimentation rate of a particle during centrifugation is determined by three forces: (1) F C, the centrifugal force, (2) F B, the buoyant force of the medium, and (3) F F, the frictional resistance to the particle’s movement.. Equation 12-13 is very important to the understanding of particle sedimentation and should be carefully examined, for the equation …
