Volumetric pipets are calibrated in a manner that takes into account the solution which remains at the tip. True Using the pipettor, you should turn the wheel on the pipette, draw up the solution until the meniscus is several centimeters above the calibration line, then quickly remove the pipette and put your thumb over the open hole of the pipet. True When the bottom of the meniscus coincides with the calibration mark, your pipet contains a precisely measured volume. True e Do not force the pipet into the pipettor, be gentle.
