Function and ventilation
Different than other dispensers Minispensor is the only dispenser which enables a non-tiredsome use. Long series of
work can be easily done. This new innovated dispenser can be operated with only three fingers. The plunger has to
be pushed down with the thumb (just like with an automatic pipette), the selected volume will then be obtained
through a spring.
Before the first use the dispenser has to be ventilated. The air caught in the supply pumps can be removed with 2-3
pumps
Volume adjustment
The Minispensor is supplied with a volume adapter , which is divided in 2 Fix-Volumina.
By rotating the pressure know you reach a second volume raster, which shows 50% of the total lift.
The two different volumina are named on the volume adaper and the arrow on the plunger, must be lined up with the
nd
2 arrow, showing on the volume adapter.

2. You now have the pressure knob (function (3)) volume adaper with the spring (4) in your hand. The PTFE-plunger
is fixed to the funciton button (5).
