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) (2 ata) (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.
