Volumetric pipette, super grade 20mL, 1 piece

Used to measure a fixed volume of liquid. Also called a volumetric pipette. There is usually only one graduation, and because the diameter of the tube where the graduation is located is narrow, the graduation is more accurate than that of a measuring pipette of the same capacity. The scale indicates the discharged volume, the volume when the liquid is sucked up to the scale and the entire amount is discharged. TD, which means delivery, is displayed. (TD: abbreviation for To Deliver) The scale indicates the volume when water at 20°C is measured. The JIS standard (R3505) specifies high accuracy Class A and standard Class B. We offer two types of products: "Custom A" with a JIS Class A tolerance, and "Super Grade" with higher precision than Class A. Our volumetric pipettes are made of DUROBAX®, a glass material with good liquid drainage. Code number: 020030-20A Material: DUROBAX(R) (borosilicate glass-2) Volume tolerance: ±0.02mm Type: Super grade Capacity: 20mL Total length: 475mm Tip outer diameter: φ3.5±0.2mm Upper outer diameter: φ7.45mm Identification color: Yellow *Manufactured with higher precision than the "volume tolerance" of JIS R3505 (1994) Class A. *Calibration certificate can be issued *As a safety measure, glass coating is available to prevent shattering.
