When you read a scale on the side of a container with a meniscus, such as a graduated cylinder or volumetric flask, it's important that the measurement accounts for the meniscus. Pasteur pipettes are not designed to measure out a specific volume; you can use them to add drops of a reagent or an indeterminate amount of a reagent, but do not use them if you need to know exactly how much reagent you are adding — for that, you should use a volumetric pipette or micropipette. GBP ... always to highest quality grade in accord to the respective standards and 'S' stands for swift delivery only used for volumetric instruments calibrated to deliver, pipettes and burettes (TD, Ex).

The units for this pipette are milliliters (ml). Volumetric pipettes are used in volumetric analysis, when there is a need for taking exact smaller volume of a sample solution or reagent. Works with all larger sizes of Mohrs, serological, or volumetric pipettes. Use this pipette filler to safely fill glass and plastic pipettes. It is often easier to see the meniscus if you put a white paper or card behind the apparatus. Practical Procedure.
