Abstract

A centrifuge including a centrifugal drum that includes a centrifugal chamber and a centrifugal chamber bottom part displaceable relative to the centrifugal drum. Also included is a piston slide axially displaceably arranged to be in and/or on the centrifugal drum. At least one seal is arranged in a surrounding groove on an outer circumference of the centrifugal drum bottom part and further arranged between the piston slide and the outer circumference of the centrifugal chamber bottom part to seal off a gap between the piston slide and the centrifugal chamber bottom part. The groove is configured to be constructed at least in sections and axially open toward the centrifugal chamber.
