Description
Pycnometer Density Bottles are precision glassware used to determine the density and specific gravity of liquids with high repeatability, particularly in analytical chemistry, petroleum and oils testing, food and beverage QC, and university teaching labs. The defined internal volume allows density to be calculated accurately from mass, which makes pycnometers ideal for checking solvent purity, verifying batch consistency, and validating formulations where small density changes indicate contamination or concentration drift.
Manufactured from high quality LabChoice BORO 3.3 borosilicate glass, these density bottles offer excellent thermal stability, low thermal expansion, and strong chemical resistance to a wide range of laboratory liquids. BORO 3.3 performance aligns with recognised borosilicate standards such as ISO 3585 and ASTM E438 Type I, supporting dependable durability and consistent behaviour under routine laboratory conditions. A well fitted stopper, typically with a fine capillary, helps expel excess liquid and minimise trapped air bubbles, improving meniscus control and supporting more consistent fills, which is critical for accurate density work.
Supplied by LabChoice Australia, Pycnometer Density Bottles are widely used across Australian universities, research institutes, and industrial quality control environments where reliable density measurement supports reportable results. For best practice, stabilise the pycnometer and sample at the calibration temperature specified for your method, dry the exterior thoroughly before weighing, and use consistent cleaning and conditioning to maintain repeatability.
