Volumetric Flask  Manufacturers, Traders, Suppliers

Volumetric flasks are also known as measuring flasks. These are vessels which are used to measure an exact concentration of a liquid. The measuring flasks are available in different shapes. The body is usually spherical, pear-shaped or conical and the bottom is flat. The neck is long and the diameter is very small and consequently the adjustment accuracy of the liquid to be measured is extremely high The neck of the volumetric flask is provided with a ring mark to identify the volume and the measuring flasks are calibrated either on an inlet or a sprue. Only volumetric flasks made of glass can be calibrated, in contrast to the measuring bottles, which are made of either borosilicate glass, polymethylpentene or polypropylene.If the measuring flasks are heated, however, slight deviations in measuring accuracy may occur. The end of the neck can form a beaded edge or a thread. volumetric flasks, together with bulb pipettes and burettes, are among the most accurate laboratory instruments for volume measurement. Often the volumetric flasks are marked with indestructible as well as acid and alkali resistant inscriptions.Marily volumetric flasks between 5 ml and 10 l are offered on the market. Volumetric flasks play an important role in chemistry.
