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. Place aligning studs
to the same side when assembling the module. See picture on page 71.
