Abstract: A bioreactor support system configured to hold a bioreactor bag, said bioreactor support system (1) comprising: —a base module (3) comprising an impeller drive unit (5); and —at least two vessel units (11a, 11b, 11c) of different sizes, which are configured to support and substantially enclose a side wall of a bioreactor bag (111a, 111b, 111c) when a bioreactor bag is provided in the bioreactor support system (1), wherein said base module (3) and said at least two vessel units (11a, 11b, 11c) comprise mating connection devices (13a, 13b, 13c, 15a, 15b, 15c) such that the at least two vessel units (11a, 11b, 11c) can be connected to one and the same base module (3) and such that the impeller drive unit (5) of the base module (3) can be used to drive an impeller (113a, 113b, 113c) in a bioreactor bag (111a, 111b, 111c) when a bioreactor bag is provided in the bioreactor support system (1).

Abstract: Systems (100, 700) and method for probe angle adjustment in bioreactor vessels are provided. The system (100) comprises a reactor vessel (110) having a reaction chamber (113), wherein the reaction chamber (113) has at least one opening (111). A probe support bar assembly (200, 300) is mounted on the reactor vessel (110) and a sensing probe (114) is mounted on the probe support bar (112) and the sensing probe (114) passes through the opening (111) on the reaction chamber (113). Movement of the probe support bar assembly (200, 300) changes the angle of inclination of sensing probe (114) inside the reaction chamber (113).

Abstract: The present invention relates to methods for securing a distributor plate to a backing plate of a chromatography column without the need for releasable fixing means as screws or bolts. The invention also relates to chromatographic columns utilizing such methods. The method employs a negative pressure or vacuum that is generated internally within the column to affix the distributor to the backing plate.
