Tip-ejector and Tip-holder
These parts must be changed, if they are
accidentally damaged or attacked chemically.
You should also remove these parts for cleaning
or decontamination purposes. A cloth
dampened with ethanol may be used to
routinely clean the outside of the pipette.
Changing the Tip-ejector
1) To remove the tip-ejector, keep the tip-
ejector button depressed and pull down on
the flanged upper part of the tip-ejector with
the other hand (moderate force is required).
2) To refit the tip-ejector, keep the tip-ejector
button depressed, slide the end of the tip-
ejector over the end of the tip-holder and
push the plastic end of the tip-ejector back
into the body of the pipette until it is gripped
firmly by the tip-ejector rod (metal).
Changing the Tip-holder
1) Remove the tip-ejector (see above).
2) Unscrew the connecting nut by turning it
counterclockwise, by hand.
3) Carefully separate the lower and upper parts.
4) Remove the piston assembly, O-ring and
seal.
5) Clean, autoclave, or replace the tip-holder.
6) Reassemble the pipette (refer to the figure).
7) Tighten the connecting nut (turn by hand,
clockwise).
8) Refit the tip-ejector (see above).
Servicing the Piston Assembly
You may remove the piston assembly for
cleaning purposes only. If the piston assembly
is changed, the pipette must be adjusted and
calibrated.
