In centrifugation the clearing factor or k factor represents the relative pelleting efficiency of a given centrifuge rotor at maximum rotation speed. It can be used to estimate the time t {\displaystyle t} (in hours) required for sedimentation of a fraction with a known sedimentation coefficient s {\displaystyle s} (in svedbergs ):
On the other hand, the centrifuge is also useful for treating water, an oil and gas by product, by removing oil contaminants before discharging back to the sea, as required by law. Moreover, emulsion of oil and water can be further treated to produce more oil by separating oil, water and impurities using the conical plate centrifuge. [2]
A tricanter centrifuge operates on a similar principle to decanter centrifuges but instead separates three phases, consisting of a suspended solids phase and two immiscible liquids. [5] Sedimentation of the suspended solids occurs as normal where they accumulate on the wall of the bowl and are conveyed out of the centrifuge.
Laboratory centrifuge. Centrifugation is a mechanical process which involves the use of the centrifugal force to separate particles from a solution according to their size, shape, density, medium viscosity and rotor speed. [1]
Benchtop fixed-angle centrifuge, or swinging bucket centrifuge Intact (eukaryotic) cells, macroscopic debris Varies depending on sample Gently lysed cells (e.g. dounce homogenizer) 600 x g 10 min Benchtop fixed-angle centrifuge, or swinging bucket centrifuge Nuclei Cytosol, non-nuclei organelles Supernatant of previous row 15,000 x g 20 min
Typical RPM for small units (2 cm) is approximately 3600RPM while larger units would operate at lower RPM depending on their size (typical speed for a 5-inch [12.5 cm] contactor is ~1800RPM). The effectiveness of a centrifugal separation can be easily described as proportional to the product of the force exerted in multiples of gravity ( g ...
