Description

The 1625 Relative Density Bottles are precision laboratory glassware instruments designed for accurate determination of liquid density and specific gravity in research, industrial, pharmaceutical, and educational laboratories. Manufactured from high-quality borosilicate glass, these relative density bottles offer exceptional chemical resistance, thermal durability, and mechanical strength for reliable laboratory performance. Equipped with an interchangeable PTFE (Teflon) stopper featuring a capillary bore, the 1625 pyknometer bottles ensure precise volume calibration and minimize evaporation or contamination during testing. These bottles comply with IS 5717 and DIN/ISO 3507 standards, making them ideal for analytical chemistry, quality control, petrochemical analysis, and density measurement applications. Available in multiple capacities including 10 ml, 25 ml, and 50 ml, the 1625 Relative Density Bottles are widely used for determining the density of liquids with high accuracy and repeatability.
