Volumetric glass pipettes allow extremely accurate measurement (to four significant figures) of the volume of a solution. These pipettes have a large bulb with a long narrow portion above with a single graduation mark as it is calibrated for a single volume (like a volumetric flask).
Volumetric glass pipettes offer precise measurement of liquids with high accuracy.
1. Select the appropriate volume pipette relating to the amount of liquid you would like to transfer.
2. Place the bottom of the pipette into the liquid you would like to transfer.
3. Draw up the liquid using a pipette bulb (squeezing the bulb) or pipette pump (rolling the pipette pump wheel).
4. Remove the pipette from the liquid and move the pipette to the required dosing point.
5. Dose liquid by releasing the pipette bulb or by pressing the release button on the pipette pump.
6. Check the amount of liquid dosed by viewing the graduations on the side of the pipette.
