volumetric pipette uncertainty

Best Answer: There is uncertainty, but that is determined when it is made -- so that value should be on the pipette itself. Sources: Senior.

what is the uncertainty of a 10ml volumetric pipette?

making solutions is a volumetric flask, and it is said to be calibrated to. like a pipette, should have greater reproducibility or less uncertainty in volume than.
