摘要：The pipette, which contains a pushbutton-operated metering piston block, an adjustment screw block connected to the latter and progressively limiting the travel of the piston block, a mechanical decimal counter to indicate the set volume, and a
discharge block and a terminal ejection block, is characterised in that its metering block is
of divisible construction in order to cover the entire metering range assumed for micropipettes. The division is achieved by mounting the adjustment block in the handle (1). The discharge block, which contains the small magnetic plate (25), is also situated in the handle (1) beneath the counter (16). The second part of the metering block is formed by replaceable metering stems which are screwed into the handle (1). The metering stems contain roller-shaped plungers (33) having various diameters.
