Straight burettes Class A supplied by LabChoice Australia provide the highest level of volumetric precision for titration, analytical chemistry and quantitative 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 burettes offer exceptional chemical durability, thermal stability and structural integrity. Class A accuracy conforms strictly to ISO 385 and ASTM E287 volumetric standards, ensuring minimal tolerance deviation and highly reproducible measurement performance in regulated and research environments.
Each straight burette features sharply defined, permanently fused graduation markings that support precise meniscus reading from any angle. The uniform bore design provides consistent liquid flow, while the precision stopcock assembly offers smooth, controlled reagent delivery during titration. PTFE stopcock models provide excellent chemical inertness for acids, alkalis and oxidising agents, while glass stopcock versions offer robust sealing performance for general laboratory applications. The clear BORO 3.3 glass body allows accurate observation of liquid levels and colour changes essential for reliable endpoint determination.
Class A straight burettes are widely used in pharmaceutical assays, water quality testing, food and beverage chemistry, environmental analysis, educational laboratories and industrial QC workflows. Their accuracy and reliability make them suitable for acid base titrations, redox reactions, complexometric analyses, calibration procedures and any workflow requiring reproducible, traceable volumetric dispensing.
All straight burettes Class A supplied by LabChoice Australia undergo ISO 9001 aligned quality control inspection. This includes verification of ISO 385 accuracy tolerances, bore uniformity checks, graduation clarity assessment, stopcock leakage testing, dimensional confirmation and chemical resistance evaluation performed according to ASTM D543 principles for polymer components. BORO 3.3 glass bodies are further inspected for thermal shock resistance and full compliance with ISO 3585 and ASTM E438 performance requirements. These rigorous quality processes ensure reliable, precise and contamination free operation for laboratories requiring premium volumetric equipment.
