WebbReading: Volumetric Flasks and Pipets Revised 3/7/12 3 Volumetric Pipet A volumetric pipet is an elongated glass bulb with two narrow glass stems at the top and bottom of the bulb (Figure 2). The pipet is used "to deliver" a single, fixed volume of liquid at a specific temperature (usually 20.0°C) from one container to another. WebbFor this, it has a set of characteristics that allows it to fulfill this function. Difference with graduated pipette-The graduated pipette has a graduated volume scale with a marking of divisions and subdivisions; while the volumetric pipette has a single gauge, and in some cases, two gauges.
