Assembling the 10 - 300 μL multi-channel pipette
1. Fit the cover plate with the integrated ejector.
2. Push the latches upwards.
3. To mount, push the lower part into the upper part until it audibly engages.
Make sure that the magnet on the piston actuator in the lower part is coupled with the magnet
on the spindle in the upper part (see p. 59).
4. Carry out a gravimetric test of the systematic and random error (see p. 63).
This test ensures that no parts were confused during assembly and that the pipette has been
assembled correctly.
Loosening and opening the 1 200 μL multi-channel
The method of loosening the 1 200 μL lower part matches that of loosening the 5 mL or 10 mL
lower parts.
1. The piston must be in its basic position before loosening the lower part. Press the rocker
down to move the piston into its basic position.
2. With the ejector pressed down, turn the lower part by approximately 30° and pull down to
cancel the magnetic coupling. This releases the lower part from the upper part.
3. View the detached lower part from above. For this, slide the housing case down. Note the
exact position of the red marked parts. The red marked stops on the housing case and the
red marked teeth on the inner part are adjacent. If the stops and teeth are on top of each
other after assembly, the housing case has been attached incorrectly.
