This is actually the very last chance to Examine if you have set the pipette to the proper volume. It is often a good idea to double check at this stage When the pipette is ready for the meant volume.
a set volume pipette is altered and manufacturing facility calibrated at a certain quantity, and dispenses exactly the same quantity of liquid each and every time you pipette. Our PIPETMAN® L mounted air-displacement pipette comes in fifteen distinct designs that cover a range of volumes among 1 μL and five mL.
