Benchtop centrifuge. Continuous flow centrifuge. Gas centrifuge. Hematocrit centrifuge. High-speed centrifuge. Low-speed centrifuge. Refrigerated centrifuges. In , Antonin Prandtl invented the first centrifuge-type machine, which was used in the dairy industry to separate milk and cream on a large scale. Following Prandtl, Friedrich Miescher, a Swiss physician and biologist, was the first to apply centrifugation in the lab. How Oil Centrifuge Filtration Works. Oil circulates from your machine into the centrifuge in a dialysis system.
Flocculation is in the process of being validated at large scale, and bioprocessors are eager to investigate it in combination with depth filtration. Several flocculation technologies exist, including the addition of the cationic polymer polyethyleneimine, which removes negatively charged cell debris and genetic materials.
Two other technologies also make depth filtration more applicable: acid precipitation resembles flocculation and dynamic body feed filtration employs a cake of diatomaceous earth that protects the filter medium from clogging. The enemy of alternative clarification techniques that rely on particle agglomeration or precipitation is feedstream variability, which may alter the distribution of flocculants, and therefore depth filtration performance.

Sedimentation field-flow fractionation SdFFF with UV detection is used to systematically investigate the effect of traditional membrane filtration and centrifugation procedures on the isolation of specific size fractions from soil suspensions.
Results showed that the membrane filtration approach seriously underestimated the total mass of particulate matter present as compared to the centrifugation approach. View Author Information.
