Measuring Cylinder Class A, Interchangeable Stopper is designed for high accuracy liquid measurement where tight tolerance readings and secure short term sealing are essential. Class A graduation accuracy supports more confident volume measurement for standards make-up, dilutions, and method controlled sample work in research, teaching, and industrial QC laboratories. An interchangeable stopper helps reduce evaporation and contamination risk when a measured volume needs to be held, transported between work areas, or protected during staged preparation.
Manufactured from high quality LabChoice BORO 3.3 borosilicate glass, the cylinder provides excellent thermal stability, low thermal expansion, and strong chemical resistance to many common laboratory reagents and solvents. BORO 3.3 glass performance aligns with recognised borosilicate standards such as ISO 3585 and ASTM E438 Type I, supporting dependable durability under routine laboratory handling and repeated temperature cycling. Smooth internal surfaces help minimise residue retention for efficient cleaning between uses, and clear graduations support consistent meniscus setting for repeatable measurements.
For laboratories specifying standards based glass volumetric ware, graduated measuring cylinder requirements are commonly referenced to ISO , and laboratory glass graduated cylinder requirements and Class A marking are covered under ASTM. Supplied by LabChoice Australia, this Class A cylinder with interchangeable stopper is a dependable choice for Australian laboratories that require consistent, reportable measurement performance.
