摘要：A pipetting apparatus is used for suction and/or for filling vessels, preferablycapillary tubes, by capillary action and for blowing liquids from vessels, preferablycapillary tubes. The apparatus consists of a housing (1) with a receiver, preferably acapillary tube receiver (13, 14), a pump (2), preferably a vane cell pump, for conveying air
in two directions (suction direction and blowing direction), and an air channel leading fromthe receiver (13, 14) to the pump (2). In order to simplify and improve a pipettingapparatus of this type, a valve (7) is provided in the air channel, which valve (7) in the restposition seals off the air channel and can be made to open.
