Maintenance
F.2.2 Multichannel Cleaning and Autoclaving
1. Remove the piston assembly from the cylinder.
2. Remove and discard the cross tubes into a biohazardous container.
3. Remove the O-rings ( only if
necessary, see section F.1
and/or F.2 for O-ring
Replacement
) and discard
them into a biohazardous
container.
4. Place all components
( see Figure F.2.2 ) into the
autoclave and autoclave at
121°C for 20 minutes.
F.2.3 Multichannel Maintenance and Reassembly
Once components are autoclaved and completely dry, use the following
procedures to relubricate and reassemble the unit:
O-ring Replacement
The O-rings may require replacement if liquids have been over aspirated. In
this case, the O-rings should be removed prior to autoclaving. Spare O-ring
packs are available through Matrix for all pipette volumes.
1. Remove old O-rings.
• 1250 µl, 850 µl, 250 µl Pipettes: O-rings can be removed from the
pistons by squeezing one side of the O-ring and lifting it out of the O-ring
groove on the piston. Once removed, the O-rings should be discarded as
biohazardous waste.
• 125 µl, 30 µl, 12.5 µl Pipettes: O-rings from these pipettes are located
in the cylinder. To remove the O-rings, unscrew the four screws that hold
the cylinder cap to the cylinder (
see Figure F.2.3a ). Once removed, the
O-rings should be discarded as biohazardous waste.
