Class A measuring cylinders supplied by LabChoice Australia provide the highest level of volumetric precision for analytical chemistry, titration preparation, calibration work and regulated laboratory workflows. Manufactured from high clarity BORO 3.3 borosilicate glass that complies with ISO 3585 and ASTM E438 Type 1 Class A standards, these cylinders deliver exceptional thermal stability, chemical resistance and dimensional accuracy. Their volumetric performance conforms strictly to ISO 4788 and ASTM E1272, ensuring minimal tolerance deviation and traceable measurement accuracy suitable for research and quality control environments.
Each Class A cylinder features sharply defined, permanent graduation markings calibrated to ISO 4788 tolerances at standard reference temperature. The tall, narrow profile allows accurate meniscus reading, while the precision formed spout supports controlled, spill free pouring during reagent transfers. A stable hexagonal or round base reduces tipping risk, enhancing safety during filling and measurement. The uniform wall thickness and high clarity BORO 3.3 glass provide reliable visibility of liquid levels, colour changes and meniscus behaviour.
Class A measuring cylinders are widely used in pharmaceutical laboratories, environmental testing facilities, academic research centres, water quality laboratories, food and beverage analysis and industrial QC workflows. Their certified accuracy makes them essential for preparing standard solutions, conducting dilution series, determining reagent volumes and supporting validated analytical procedures. The inert borosilicate composition ensures compatibility with acids, alkalis, organic solvents and hot liquids, preserving measurement integrity across diverse applications.
All Class A measuring cylinders supplied by LabChoice Australia undergo ISO 9001 aligned quality control inspection. This includes verification of ISO 4788 volumetric accuracy, dimensional conformity checks, graduation clarity assessment, thermal shock testing and chemical resistance evaluation performed according to ASTM D543 where applicable. Cylinders are further validated for full compliance with ISO 3585 and ASTM E438 borosilicate performance standards. These rigorous measures ensure long term reliability, accuracy and safety for laboratories requiring premium volumetric glassware.
