Disclosed and described is a hose for attachment to a dispensing cartridge for placement in a peristaltic pump, for stretching over a rotor of the peristaltic pump, and for conveying a medium by external mechanical deformation of the hose. The hose has a length of preferably 20 mm to 200 mm, an internal cross-sectional area of 0.07 to 7.07 mm, and a wall thickness of 0.3 mm to 2.2 mm. Thickenings are formed at both ends of the hose and the distance between the thickenings is 40 mm to 100 mm. According to the invention, it is provided that the hose is manufactured by an injection molding process, the inner cross-sectional area has a tolerance of at most±33%, and the hose is suitable for closing completely when stretched over the rotor with a tension force of 1 to 10 N.

Injection-molded hose

A dispenser cassette is shown and described for attachment to a peristaltic pump that has a first cartridge, second cartridge, and tubes, which are accommodated in the dispenser cassette such that both ends of the tubes are each inserted into one of the cartridges. According to the invention, the two cartridges are connected to one another by an elastic connector.

Dispenser cassette for use in a peristaltic pump

The invention pertains to a handheld pipette () with a handle (), an interconnecting part () to attach a pipette tip and an ejection mechanism to remove the pipette tip from the interconnecting part (). The ejection mechanism has a movable slider () relative to the interconnecting part () in the area of the interconnecting part (that is designed to slide the pipette tip from the interconnection part () when operating the ejection mechanism. The pipette () furthermore possesses a first and a second operating element () accessible from the outside to operate the ejection mechanism, whereby the first operating element () is arranged in the area of the handle () and is operable by hand, and where the second operating element () is intended to be operated by an external device ().
