Jan 27, 2024 · A volumetric flask is a piece of laboratory glassware designed for preparing solutions. It has a flat-bottomed bulb with a long neck, calibrated to hold a precise volume at a marked point on the neck.
Volumetric Glassware – A Reagecon Guide. Introduction. Volume measurement is one of the routine tasks in the laboratory. Typical volumetric instruments, such as one-mark and graduated pipettes, burettes, volumetric flasks and cylinders are therefore part of the basic requirement.
Mar 17, 2015 · A number of pieces of chemistry glassware are used to accurately measure volumes; the most obvious being the graduated cylinder, or measuring cylinder, which can come in a variety of sizes. For measuring volumes of solutions more precisely, a volumetric pipette can be used.
Dec 3, 2018 · A volumetric flask is a piece of laboratory glassware that is used to prepare and measure chemical solutions. It is used to make up a solution to a known volume. Volumetric flasks measure volumes much more precisely than beakers and Erlenmeyer flasks.
- Anne Marie Helmenstine, Ph.D.
Volumetric glassware or volumetric flasks are containers that have been calibrated to a specific volume. These flasks, unlike Erlinmeyer flasks or beakers, are marked with lines that are calibrated to a specific volume of liquid.
Volumetric glassware is used when it is necessary to prepare solutions of a precisely known concentration. Volumetric flasks are manufactured to a high accuracy and are labelled with their volume and a precision. Different grades of volumetric glassware are available depending on how accurate the solution needs to be for a particular purpose.
It is often used to deliver a certain fraction (aliquot) of a solution. Two common types of pipettes are used in laboratories; the volumetric or transfer pipette and the measuring pipette. Pipettes are designed ‘to deliver’ a specified volume at a given temperature.
