    Abstract: A process is disclosed for reducing or removing endotoxins from compositions containing therapeutic active substances extracted from natural sources by genetic engineering and/or biotechnology. For that purpose, the compositions are treated with chromatographic materials. The natural sources are disintegrated, the thus obtained fractions are, if required, centrifuged, filtered or treated using affinity chromatography methods, the fractions are pre-incubated in an aqueous salt solution and detergents, are treated with anion exchange materials, then washed with another salt solution. The active substances are eluted from the anion exchanger then further purified in a manner known per se.

    Abstract: A device (10) for separating liquid samples has a sample container (12), bottom wall (20) of which has an outlet opening (22) provided therein. The outlet opening (22) is joined by an outlet spout (24) extending in the axial direction of the sample container (12). On bottom wall (20) there is a separation layer (28). Below sample container (12), a collecting container (32) is arranged abutting sample container (12) such that an exchange of air between the interior of the collecting chamber (32) and the environment is possible, yet an escape of liquid is largely inhibited. The contact surface between collecting chamber (32) and sample container (12) and end (26) of the outlet spout (24) through which the liquid is discharged, are axially spaced apart.

    Abstract: There is described is a process for the isolation and purification of nucleic acids such as plasmid or genomic DNA from cells or other sources, wherein a) the cells containing nucleic acids are digested and cell debris is removed, or other samples containing nucleic acids are treated with anion exchangers, namely, in buffer solutions of low ionic strength, b) thereafter, the nucleic acids are desorbed from the anion exchanger using a buffer of high ionic strength, in order to be subsequently c) treated in said buffer of high ionic strength or in the presence of lower alcohols and/or poly(ethylene glycol) with a mineral support material, with adsorption of the nucleic acid to the surface of the mineral support materials, whereupon d) desorption of the nucleic acid is effected using water or a buffer solution of low ionic strength. The device for operating the inventive process consists of a hollow body (1) with an inlet opening (7) and an outlet opening (8), wherein in the hollow body (1), between two securing means (5, 6), a powdered first material based on silica gel (10) is arranged, and a second material (11) is placed between the first material (10) and the outlet opening (8), the first and second materials (10, 11) having different adsorption characteristics for nucleic acids.
