Abstract

A filtration device (10), in particular a small-scale filtration device for production of biopharmaceuticals, comprises a top cover (12) having an unfiltrate inlet and a bottom cover (16) having a filtrate outlet (20), and one or more filter supports (23) arranged as a stack between the top cover (12) and the bottom cover (16) along a vertical direction (A). Each filter support (22) is configured to support a flat filter (24), especially a membrane. The filter support(s) (23) are provided on the top cover (12) and/or on the bottom cover (16) and or on one or more optional, preferably disc-shaped, filter support plates (22). The top cover (12), the bottom cover (16) and the filter support plates (22) each have an inner portion with at least one inner welding section (26) and an outer portion with at least one outer welding section (28). The inner welding sections (26) have an annular shape fully encircling a vertical filtrate collection channel (30) of the filtration device (10) which leads to the filtrate outlet (20). The outer welding sections (28) have an annular shape fully encircling a filtration area of the filtration device (10). All inner welding sections (26) are substantially congruent and welded in a fluid-tight manner to a corresponding inner welding section (26) of the top cover (12) or bottom cover (16) or a neighboring filter support plate (22), so as to form an inner housing portion (32) of the filtration device (10). All outer welding sections (28) are substantially congruent and welded in a fluid-tight manner to a corresponding outer welding section (28) of the top cover (12) or bottom cover (16) or a neighboring filter support plate (22), so as to form an outer housing portion (34) of the filtration device (10).
