A: This is the standard technique for using a graduated pipette :
Hold pipette in solution, don’t touch the bottom.
Squeeze bulb and attach to top of the pipette.
Hold forefinger on top of pipette to control volume aspiration.
Subtract the amount needed into separate beaker while staying eye level to assure proper measurement.
