laboratory glass Volumetric flask with glass stopper

Whatsapp Order


A volumetric flask with a glass stopper is a type of laboratory glassware designed for precise liquid measurement. It features a long, narrow neck with a single calibration mark that indicates a specific volume when filled to that point. The body of the flask is pear-shaped or bulbous, allowing for easy mixing of liquids. The glass stopper ensures a tight seal, preventing contamination or evaporation of the contents.

This flask is primarily used in preparing accurate standard solutions and for dilution in quantitative chemical analysis. Its precise calibration and secure stopper make it ideal for tasks requiring accuracy in both preparation and storage of solutions.

Uses

  • Preparing Standard Solutions: The volumetric flask is primarily used to prepare standard solutions with high precision. The narrow neck allows for accurate measurement to a fixed volume, indicated by the calibration mark on the neck.
  • Dilution of Solutions: It is ideal for diluting concentrated solutions to a precise final volume. The accurate calibration ensures that the desired concentration of the solution is achieved after dilution.
  • Titration Preparation: In titration experiments, the volumetric flask is used to prepare solutions that will react with the titrant. Its precision is crucial for ensuring accurate titration results.
  • Quantitative Analysis: The flask is essential in quantitative chemical analysis, where precise solution concentration is critical for calculating chemical quantities or reactions.
  • Storage of Solutions: The glass stopper makes the flask ideal for storing sensitive or volatile solutions that need to be protected from contaminants, air, or evaporation over short periods.
  • Reaction Vessel: In some cases, the volumetric flask can act as a reaction vessel where solutions are combined and mixed for chemical reactions.
