Embodiment Construction

[0029] figure 1 A cross-sectional side view of a filter holding device 1 according to an embodiment of the invention is schematically shown. The filter holder 1 is arranged in a flexible bag 3 .

[0030] The filter holder 1 is suitably a flat or slightly curved plate. The filter holder 1 comprises some kind of distance means on one side of the middle part 5 of the filter holder. This distance means may eg be a rib or a screen or some other kind of structure. The distance means are provided on the side of the filter holder to which the filter 7 should be attached. In this description the word filter is used, but it could also be a membrane or a bioprocessing separation device used to retain or retain material. The distance means in the form of ribs are further shown and described with respect to Fig. 3b. The filter holder 1 further comprises a filter sealing area 9 which is arranged around the distance means. The filter sealing area 9 is arranged to seal to the periphery ...

Abstract

A filter holding device (1; 41; 75; 81) is arranged for providing at least one filter (7; 43a, 43b; 85) inside a flexible bag (3; 71). The filter holding device comprises attaching means (19a-d, 21a-d; 79; 83) for attaching the filter holding device to an inner surface of the flexible bag such that the at least one filter held by the filter holding device is provided at a distance from the inner surface of the flexible bag.

Description

technical field [0001] The invention relates to a filter holding device arranged to provide at least one filter inside a flexible bag. Background technique [0002] The bioprocessing industry has traditionally used stainless steel systems and piping in manufacturing processes for fermentation and cell culture. These devices are designed to be steam sterilized and reused. But cleaning and disinfection are costly and labor-intensive operations. Furthermore, the installation costs of these traditional systems with the required plumbing and instrumentation are often prohibitively high. Furthermore, these systems are typically designed for a specific process and cannot be easily reconfigured for new applications. These limitations led to a new approach using plastic, single-use disposable bags and tubing that took a decade to replace the usual stainless steel tanks. [0003] Specifically, bioreactors traditionally made of stainless steel are replaced in many applications by d...
