Somebody else suggested throwing out an out of calibration pipetman.
DON'T DO THAT. IT IS POSSIBLE TO RECALIBRATE A PIPETMAN.
Bill Warren had a good discription of cleaning the plunger, barrel
and o-rings. I have a copy of a protocol for the whole
process, including instructions on how to calibrate the things.
I believe Gilson also sells a tool for adjusting the calibration
on their newer models. For the older models, an allen wrench and
a screw driver are all that is needed.
I will try to transcibe a copy of the protocol here,
but if anyone else knows of an electronic copy of a
similar protocol, it will save me much typing.
