621A Grade A volumetric flask
Product features:Volumetric flask is a precise instrument used to prepare solutions with an accurate amount and concentration of a certain substance. It is a slender-necked, pear-shaped, flat-bottomed glass bottle with a ground glass stopper and a graduated neck. But there are also two marking lines engraved on it, the upper one indicating the measured volume. It is mainly used for directly preparing standard solutions and accurate diluted solutions as well as preparing sample solutions. The volumetric flask is also called a measuring flask.

Volumetric flask is a precise instrument used to prepare solutions with an accurate amount and concentration of a certain substance. It is a slender-necked, pear-shaped, flat-bottomed glass bottle with a ground glass stopper and a graduated neck. But there are also two marking lines engraved on it, the upper one indicating the measured volume. It is mainly used for directly preparing standard solutions and accurate diluted solutions as well as preparing sample solutions. The volumetric flask is also called a measuring flask.

Grade A volumetric flasks are manufactured strictly in accordance with national standards. Their capacity errors are extremely small and can meet the needs of high-precision experiments. For example, in some experiments that require very precise solution concentration, such as trace analysis, drug development, etc., using grade A volumetric flasks can ensure the accuracy of experimental results.

Volumetric flask is made of thickened glass, with high temperature resistance, no bubbles, fine workmanship, strong and durable, and high transparency; the bottle mouth is frosted, and the cap is universal. Two caps are available, solid glass stopper, PP plastic cap, good sealing and long-lasting durable; the product information is clearly marked, not easy to wear, and the specifications are complete, which brings convenience to experiments; the base is smooth, the bottom of the bottle is round and wide, the placement is stable, it is exquisite and beautiful without protrusions, it is beautiful and generous, and the workmanship is solid.
