The pipette is a device for quantitatively transferring liquids. It is widely used in the fields of biology, chemistry, and clinical diagnostic laboratories, biotechnology laboratories, pharmacy and chemical laboratories, environmental laboratories, and food laboratories. Commonly used are manual adjustable pipettes and electric ones. There are also many optional specifications according to the volume of liquid to be piped.

● Aspirate liquid vertically.
●For 5mL and 10mL pipettes, the tip needs to be immersed in the liquid surface 5mm, aspirate the liquid slowly, after reaching the predetermined volume, pause under the liquid surface for 3 seconds, and then leave the liquid surface.
● Slowly release the controller when aspirating liquid, otherwise the liquid will enter the tip too quickly and the liquid will be sucked into the pipette
● When sucking volatile liquid, you need to rinse the suction head 4-6 times to saturate the steam in the sleeve chamber to avoid liquid leakage.
