Flask Volumetric B 20ml

A volumetric flask is a type of laboratory glassware used for preparing solutions at a precise volume and concentration. It has a flat bottom, a long narrow neck, and a single calibration mark etched on the neck, indicating the exact volume it holds (e.g., 100 mL, 250 mL, 1 L). Volumetric flasks are used when high accuracy is required, such as in titrations or analytical chemistry. They are typically made of borosilicate glass or plastic and come with a stopper to prevent contamination or evaporation.
