Viruses are precipitated from the supernatant by incubation with PEG 8000 (80 g/L) and NaCl (17.5 g/L) during agitation (100 rpm) overnight at 4˚C, followed by centrifugation for 90 min at 13,000×g. The resulting virus-containing pellet is eluted in 1 mL phosphate buffer saline (PBS) and stored at -80˚C before further processing. ...
Decanter Centrifuge The scroll type (decanter) continuous conveyor-discharge centrifuge is characterized by a horizontal conical bowl. The bowl contains a screw conveyor that rotates in the same direction but at a slightly higher speed. Feed enters through an axial tube at the center of the rotor, passes through openings in the screw conveyor, ...
