Abstract

An expressor includes a base and a first platen extending from the base. A second platen is movably mounted to the base so that the second platen can move between a collapsed position where the secondplaten is moved toward the first platen and a retracted position where the second platen is moved away from the first platen. At least a portion of the second platen is spaced apart from the first platen by a gap spacing when the second platen is in the collapsed position. Either the first platen or the second platen is releasably attached to the base so that a width of the gap spacing when the second platen is in the collapsed position can be selectively adjusted.

Description

[0001] Cross References to Related Applications [0002] This application is a continuation-in-part of US Application Serial No. 16 / 289,296, filed February 28, 2019, which is specifically incorporated herein by reference. technical field [0003] The present disclosure relates to extruders, extruder systems, and related methods for expelling liquid supernatants from collapsible bags that also contain clumps of cells or microorganisms. Background technique [0004] Bioreactors and fermenters are used to grow various types of biological suspensions. Such suspensions are broadly defined as liquid media comprising cells or microorganisms and in which they are suspended. Once the suspension is sufficiently grown, the biological suspension is typically separated into components, and the separated components are then harvested for subsequent analysis or use. Centrifugation is a technique frequently employed during the isolation or analysis of various cells, organelles, and biopo...
