Move the pipette to the receiving vessel and dispense the liquid by gently pressing the pipette knob to the first stop. After about one second, keep on pressing pipette knob to the second stop. This action will completely empty the tip from the liquid. Afterwards withdraw the tip from the liquid and release the pipette to the ready position.

Move the pipette to the receiving vessel and dispense the liquid by gently pressing the pipette knob to the first stop (#3). Withdraw the tip from the liquid. Some liquid will remain inside the tip. The liquid remaining in the tip can be dispensed back into the original solution (#4) or thrown away. Release the pipette thumb to the ready ...
Pipettes come in several designs for various purposes with differing levels of accuracy and precision, from single piece glass pipettes to more complex adjustable or electronic pipettes. Many pipette types work by creating a partial vacuum above the liquid-holding chamber and selectively releasing this vacuum to draw up and dispense liquid ...
The increased water content softens the stool and stimulates the bowel to contract (move its contents to the rectum). Sodium lauryl sulfoacetate improves the wetting and penetrating abilities of the solution, sorbitol enhances the water-releasing effect of sodium citrate and glycerol helps to lubricate the stool.
Glycerol has high dynamic viscosity, [8] and if a researcher aspirates a sample of glycerol too quickly with an air displacement pipette, It will draw up an air bubble. [1] When a researcher attempts to dispense the liquid, some of it will stick to the pipette tip wall, dispense very slowly and remain in the tip. [9]
