Pycnometer density bottles supplied by LabChoice Australia provide highly precise volumetric vessels for determining the density, specific gravity and purity of liquids and fine solids across analytical, industrial and research laboratories. Manufactured from premium BORO 3.3 borosilicate glass that complies with ISO 3585 and ASTM E438 Type 1 Class A standards, these bottles offer exceptional thermal stability, chemical resistance and dimensional accuracy. Their calibrated volume and precision ground components support accurate density determination in accordance with established analytical methods.
Each pycnometer features a finely ground stopper with a capillary vent hole engineered to ISO 383 and ASTM E676 joint specifications, ensuring airtight sealing while allowing excess sample and air to escape during filling. This design ensures a reproducible fill level and eliminates trapped air, enabling high accuracy measurements essential for compliance with ISO 3507 volumetric tolerances for laboratory pycnometers. The uniform wall thickness and high clarity BORO 3.3 glass provide excellent visibility of liquid meniscus, sample clarity and fill behaviour during calibration and measurement.
Pycnometer density bottles are widely used in pharmaceutical testing, petrochemical analysis, food and beverage QC, forensic science, materials research, environmental laboratories and academic teaching facilities. They support density determination of oils, alcohols, aqueous solutions, suspensions, powders and volatile solvents. Their precision calibrated volume enables reliable correlations with reference temperature data, allowing laboratories to generate accurate density profiles, purity assessments and quality control metrics.
Every pycnometer supplied by LabChoice Australia undergoes ISO 9001 aligned quality control inspection. This includes verification of ISO 3507 volumetric accuracy, dimensional conformity checks, stopper joint fit testing, clarity assessment and thermal shock evaluation. All BORO 3.3 bodies and stoppers are validated for compliance with ISO 3585 and ASTM E438 borosilicate performance standards, while joint tolerances are confirmed against ISO 383 and ASTM E676 requirements. These rigorous procedures ensure stable, reproducible and contamination free density measurements for laboratories requiring precision analytical glassware.
