Abstract: A method for recovering a desired component from a sample solution with beads under stabilized fluidized bed conditions is provided. Also provided are support beads for use in downstream processing which comprise a polymer matrix into which glass or silica particles have been incorporated.

Abstract: Support beads for downstream processing including a polymer, esp. a polysaccharide, matrix into which glass or silica particles, preferably quartz particles, have been incorporated, and their use in downstream processing, especially stabilized fluidized bed separations.

Abstract: The invention relates to a method for dewatering particle collections with the aid of a filter press in a cyclic sequence comprising filling, dewatering and emptying stages. The various stages within each cycle and between consecutive cycles are followed-up and determined by measuring continuously a magnitude which varies with the mass of the press and its contents, preferably the pressure exerted by the press and its contents on the surface supporting the press.

Abstract: The present invention relates to a method of and apparatus for pressure filtering, the pressure filter (1) used comprising pressure plates (3,4,5,6), which can be pressed against each other. Pressure chambers (8) are formed between the pressure plates and in each one of the pressure chambers two substantially vertical filter cloths are mounted. In order to loosen the filter cakes (32) from the filter cloths (9), means are used to produce sudden acceleration forces, e.g. directly or indirectly acting blow devices (34,36,38) or blow devices or lifting means, cooperating with stop surfaces, which devices and means are designed to drop the guide rails (12) from a lifted position, and/or shear forces, e.g., devices to displace the lower ends of the filter cloths in respectively opposite directions in the planes of the cloths.

Abstract: A separation material of crosslinked agarose in which the agarose is crosslinked using at least one bi- or polyfunctional crosslinking agent, which gives a chain of 6 to 12 atoms between two binding points, on one hand and using at least one bifunctional crosslinking agent, which gives a chain of 2 to 5 atoms between two binding points on the other.The separation material is prepared by crosslinking agarose in two steps with (a) a bi- or polyfunctional crosslinking agent, which gives a chain of 6 to 12 atoms between two binding points and (b) a bifunctional crosslinking agent, which gives a chain of 2 to 5 atoms between two binding points, preferably in the order mentioned.
