Abstract: The peristaltic pump is provided with a two-piece housing (2, 3), in which a conveying member (1) as well as a pump tubing section (6) squeezable by the conveying member is received. For fixing the pump tubing section (6) in the housing (2, 3), a tubing holder (4) is provided. Further provided is a connecting element (5) provided with duct shaped connecting sockets (14a, 14b) for connecting tubing sections (15a, 15b). For connecting the pump tubing section (6) to the tubing holder (4), the two ends of the particular pump tubing section (6) are fixed in receptacles (10a, 10b) of the tubing holder (4), which positively enclose the outside of the pump tubing section (6). The connecting element (5) is fixed to the tubing holder (4) by means of a snap-on connection. Thereby, the connecting sockets (14a, 14b) thereof are sealingly connected to the particular pump tubing section (6).

Abstract: The invention relates to a device for automated bioreactor sampling connected to a reactor comprising a sampler, at least one tube fluidly connecting said reactor with said sampler and a pump for pumping fluids from said reactor to said sampler and vice versa. Particularly simple and essentially dead volume-free sampling can be achieved by providing means for flushing at least parts of the tube with gas/sterile air between individual sampling steps. The invention furthermore relates to a method of operation of such a device.
