Measuring flask (volumetric flask, super grade) brown 2000mL 1 piece

Used to measure a fixed volume. Also called a volumetric flask. It consists of a flat-bottomed flask with a long, narrow neck that usually has a single wire in it. Because the diameter of the neck where the graduations are located is narrow, the graduations are more accurate than those of a measuring cylinder of the same capacity. It is used to precisely adjust the concentration of a given reagent. The scale indicates the received volume (volume contained), and is marked with TC, which stands for To Contain. The scale indicates the volume when water at 20°C is measured. This is more accurate than the "volume tolerance" of JIS standard (R3505) Class A. The outside is dyed brown to block out light. Material: Borosilicate glass-1 TS Glass Flat Stopper Height: 400mm Capacity: 2000mL Color: Brown Volume tolerance: ±0.5mL Stopper (TS): 27 Outer diameter: φ160mm *Manufactured with higher precision than the "volume tolerance" of JIS R3505 (1994) Class A. *Proofreading is not available. *As a safety measure, glass coating is available to prevent shattering.
