temp and pressure will make a variation but a very subtle one. (so 500ul =
I have calibrated pipettes this way, and I could send you the
calibration forms as an attachment privately (off histonet).
I have found that it is cheaper to have a pipette service calibrate them

This university has quite a few pipettes, so I'm sure there is a deal there.
This includes a cleaning, replacement of worn gaskets, and a limited
warrantee. How much would you be paying a tech to make these measurements?
How long could you milk the clock in doing these measurements? I'd probably
be willing to pay twice that $15 service fee and still smile.
