Essential volumetric glassware for precise solution preparation, volumetric flasks are designed to measure and contain a single, exact volume. Featuring a flat base, a long narrow neck and a clearly defined calibration mark, they enable accurate dilution and preparation of standard solutions. Manufactured from chemically resistant borosilicate 3.3 glass, these Class A volumetric flasks provide excellent thermal and chemical stability. Typically supplied with compatible stoppers, they are widely used in analytical, research, industrial, quality and teaching laboratories.
