Class B measuring cylinders supplied by LabChoice Australia provide reliable, accurate and durable volume measurement for teaching laboratories, general analytical workflows and routine solution preparation. Manufactured from high clarity BORO 3.3 borosilicate glass that complies with ISO 3585 and ASTM E438 Type 1 Class A standards, these cylinders offer excellent chemical resistance, thermal stability and long term structural reliability. Their volumetric performance follows the tolerance limits specified in ISO 4788 and ASTM E1272 for Class B accuracy, making them ideal for routine laboratory tasks where absolute precision is not critical.
Each Class B cylinder features clear, permanent graduation markings designed for easy meniscus reading during routine measurements. The tall, narrow shape supports accurate volume estimation, while the precision moulded spout allows controlled, spill free pouring of reagents and solutions. Bases are constructed for stability during filling, measurement and transfer, reducing tipping risk in high throughput or educational settings. The high clarity BORO 3.3 glass provides strong visibility of liquid level, meniscus behaviour and sample clarity.
Class B measuring cylinders are widely used in school and university laboratories, environmental testing, industrial QC, food and beverage workflows and general wet chemistry applications. Their durable construction supports heating, cooling, washing and routine handling, making them ideal for buffer preparation, reagent makeup, dilution tasks and approximate volumetric work. The inert borosilicate composition prevents chemical interaction with acids, bases, salts and solvents, ensuring consistent measurement performance.
All Class B measuring cylinders supplied by LabChoice Australia undergo ISO 9001 aligned quality control inspection. This includes verification of ISO 4788 volumetric tolerances, dimensional accuracy checks, graduation legibility assessment, thermal shock testing and chemical resistance evaluation conducted in accordance with ASTM D543 principles. Cylinders are additionally validated to ensure full compliance with ISO 3585 and ASTM E438 performance requirements for BORO 3.3 laboratory glassware. These rigorous quality measures support dependable, safe and long lasting operation for laboratories requiring robust volumetric equipment.
