After use, the motor unit has to be pulled out of the centering part of DOSER or HI-DOSER glass vessel, until both separate. Do not be afraid to pull hard, as the blocking mechanism requires it and at the same time care should be taken to remove it axially and not at any other angle.

Loosen both threaded caps and separate all components inside the glass vessel. Care should be taken not to damage the distributor while dismantling the unit (pull it out axially).

The parts can now be washed by common laboratory methods (for example, with ethanol, acetone, diluted acids or bases). It is however not recommended to expose parts to these reagents for long periods of time.

The motor and control unit can be cleaned only with a piece of cloth soaked in water containing a mild detergent, diluted ethanol or with more care iso-propanol. Use of other solvents could damage the surface of the control unit.
