Centrifugation SOP template 2 Revised: 06/2019 MTD 1. Purpose and Scope of Work/Activity: The process of centrifuging samples is extremely useful and employed in a variety of laboratories. A centrifuge spins samples at a high speed, the centrifugal force causes denser materials to travel to the bottom of the centrifuge tube rapidly.

Dec 09, 2019 The purpose may be to obtain a decant (liquid free from particulates) or to recover the precipitate. ... The separation may be enhanced using centrifugation. If a centrifuge is used, the solid may be compacted into a pellet, making it possible to pour off the decant with minimal loss of liquid or solid.

Some general comments about gas exchange and diffusion will be made, followed by a description of how oxygen is carried in the blood. The binding of oxygen to hemoglobin will be discussed, including the oxygen saturation (or dissociation) curve and factors (allosteric effectors) which cause it to shift. Next, a discussion of the effects of carbon monoxide on oxygen binding …

Typically, centrifugation at 1000 x g for 10-15 minutes is sufficient to sediment bacteria.After the specimen has been centrifuged, the supernatant should be drawn off with a Pasteur pipette and reserved if antigen detection by latex agglutination is planned. The sediment should be vigorously mixed (e.g., in a closed tube using a vortex machine).
