Maintenance/Cleaning

Note: All maintenance should be carried out wearing suitable eye protection and protective clothing. If in
doubt, consult your safety officer.
1. Make sure that the Zippette Pro is completely empty and turn the anti-drip tap to 'Open' position.
2. Place the instrument into an empty sink together with its reservoir. Unscrew the threaded platform base
from the reservoir and lift the dispenser's intake tube carefully out of the reservoir, whilst tapping it
against the reservoir's aperture to shake off any droplets from the intake tube.
3. Hold the dispense nozzle over the aperture of the reservoir and apply gentle piston strokes in order to
return any syringe contents into the reservoir.
4. Flush out remaining glass barrel contents with distilled water or a suitable solvent. This will preserve the
smooth action of the piston and free action of the inlet and outlet valves. If the inlet valve does stick and
is not freed by flushing, it may be freed by gently inserting a thin rod into the inlet aperture and gently
pushing the ball off its seating. Re-check unit for operation.
5. Empty the instrument completely after cleaning, and flush through with distilled water.
