To pipet using a volumetric pipet, first, rinse the pipet with the solution to be pipetted to ensure it is clean and free of any residue. Then, use a pipette filler to draw the solution up to the calibration mark on the pipet. Slowly release the solution into the desired container and wait for a few seconds to allow the last drop to fall. Do not blow out the remaining solution. To accurately dispense 10ml of solution using a serological pipet, use a 10ml serological pipet and make sure to fill it up to the calibration line marked on the pipet.
