Measuring flask (volumetric flask, custom A) 250mL 026050-250 1pc

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. Complies with JIS standard (R3505) Class A "Volume tolerance". Capacity (mL): 250 Stopper (TS): 16 Outer diameter (Φmm): 81 Height (mm): 235 Volume tolerance (mL): ±0.15 Material: Borosilicate glass-1 TS Glass Flat Stopper *Manufactured to JIS R3505 (1994) Class A "volume tolerance". *Height does not include stopper *As a safety measure, glass coating is available to prevent shattering.
