Service Instructions for Multichannel Pipette Tip Cones
To ensure even performance between all channels in a multichannel pipette, all tip cones
have to be changed at the same time, if any of them needs to be changed. Don't mix tip
cones of different packages, because one bag contains a matched set of tip cones.
Sterilization
The entire pipette can be sterilized by autoclaving it at 121°C (252°F) (minimum 20 minutes).
No special preparations are needed for autoclaving. You can use steam sterilization bags if
needed.
After autoclaving the pipette must be cooled to room temperature for at least two hours.
Before pipetting, make sure that the pipette is dry. We recommend that you check the
calibration after every sterilization cycle to achieve the best possible accuracy.
The table below lists possible problems and their solutions.
