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.
