摘要:
A mixing system has a single-use container (1) with flexible walls and a mixing device. The mixing device has at least one encapsulated drive (5) and a mixer shaft (3). The drive (5) can be disposed of after use together with the mixer shaft (3) and the single-use container (1). The mixing system can be used in biotechnology and the pharmaceutical industry for mixing liquids, dissolving solids or cultivating cells and microorganisms.
摘要:
A cleaning method for a filter testing device (10) including switching devices (V1–V6), external connections (12, 14, 16, 18, 20) and internal volumes (24, 26, 28, 30, VV1–VV5) that can come into contact with a fluid from a filter device that is to be tested. The cleaning method involves the steps of: selecting one or more internal volumes (24, 26, 28, 30, VV1–VV5) to be cleaned, cleaning the selected internal volumes (24, 26, 28, 30, VV1–VV5) with a cleaning fluid by correspondingly switching the switching devices (V1–V6), and removing the cleaning fluid contained in the internal volumes (24, 26, 28, 30, VV1–VV5) from the internal volumes. Also a computer program product with program parts for implementing the method of the invention or a preferred embodiment thereof, and a filter testing device adapted to be cleaned by the method of the invention.

A bioreactor (1) having a container (2), a shaft housing (3) for guiding a shaft (5) through a wall (7), a stirrer (6) connected to the shaft (5) in the interior (9) of the container (2), and a drive (4) arranged outside the container (2) and connectable to the shaft (5). The shaft (5) is mounted in the shaft housing (3) via at least one ball bearing (23) and is sealed in relation to the shaft housing (3) by at least one seal (11, 20). The seal (11, 20) is configured as a radial shaft seal (28) having two sealing lips (30, 31) that are arranged one behind the other in the longitudinal direction of the shaft (5) and are able to run on the shaft (5) without lubricant.
摘要:
The invention relates to a plate heat exchanger comprising a plurality of plates having flow channels, wherein a first plate has a front side having at least one flow channel for a first fluid and a second plate has a front side having at least one flow channel for a second fluid, and wherein the plates have through openings via which the flow channels for the same fluid are respectively connected to one another, wherein a front plate, which is placed in front of the front side of the first plate, has ports for the first fluid and for the second fluid, wherein an end plate forms the end of the aligned plates, wherein the plates and ports are formed from plastic, and wherein the plates are bonded or welded tightly together.

A mixing system has a container with flexible walls (1), a fluid-tight drive space (6) and a mixing device. The container with flexible walls (1) has at least one head plate (5). The fluid-tight drive space (6) is outside of the container interior (2), and is enclosed by the head plate (5) and a cap (7) attached to the head plate (5). The mixing device has a stirrer shaft (3), onto which stirrer elements (4, 4′) are attached. The stirrer shaft (3) is guided from the container interior (2) through an opening in the head plate (5) and the section of the stirrer shaft (3) in the drive space (6) is guided by bearings (9, 10). A seal (8) is fit into the opening of the head plate, and encloses the stirrer shaft (3) and seals the container interior (2) from the drive space (6).
