Please see page 3 (Fig. 1) of this manual.
A general description of disassembly and assembly for all single-channel models
is followed by instructions on how to replace specific parts for special pipette
types.
A Disassembly and assembly (Fig. 1 / point 1)
Disassembly
– Hold down the ejection button on the side of the pipette and pull off the
ejection sleeve (12) using force.
An exception is the 1 – 10 mL model:
see Section B "Replacing pistons and seals".
– Unscrew the pipette lower part (10) from the grip by turning it to the left
(if necessary, use position A of the wrench provided).
– Press the piston holder (1) together and remove it.
The piston is subject to spring tension!
– Remove the piston (3) with spring (4) and replace if necessary.
Assembly
– Insert the piston (3) with spring (4) into the pipette lower part.
– Place the piston holder (1) over the piston, press it together and slide it into the
grooves on the lower part.
– Screw the pipette lower part hand-tight into the grip. (Do not use the wrench.)
– Hold down the ejection button and re-attach the ejection sleeve.
B Replacing pistons and seals
For fixed- and adjustable-volume (variable) pipettes up to 20 µL (see Fig. 1 /
point 2):
– Disassemble the pipette.
– The seal is changed by replacing the entire pipette lower part (10).
