The volumetric flask is used to formulate the prescribed solution or to dilute the test solution. Pipette used to remove or add a volume of solution. Burettes for titration fluid (usually a predetermined solution) for titration. Volumetric Flask - The volumetric flask is a pear-shaped flat bottomed flask with a long, narrow neck (Figure 1). It is generally worn with a grind plug (also available without a glass stopper). In the Wai
