Description
Burette with Straight Bore and PTFE Key Stopcock, Class A Accuracy is designed for high precision volumetric dispensing in titration and quantitative analytical work where tight tolerance readings and repeatable delivery are critical. The straight bore profile supports consistent flow characteristics, helping deliver smoother control from bulk delivery through to dropwise endpoint approach. It is widely used for acid base, redox, complexometric, and precipitation titrations across research laboratories, calibration workflows, and industrial quality control where measurement confidence directly impacts results.
Manufactured from high quality LabChoice BORO 3.3 borosilicate glass, the burette offers excellent thermal stability, low thermal expansion, and strong chemical resistance to a wide range of laboratory reagents. BORO 3.3 performance aligns with recognised borosilicate standards such as ISO 3585 and ASTM E438 Type I, supporting durable service under daily handling and exposure to common titrants and solvents. The clear graduation marking and smooth internal surfaces support accurate meniscus reading and reduced residue retention, improving repeatability between runs and assisting efficient cleaning.
The integrated PTFE key stopcock provides smooth, precise flow control with broad chemical compatibility and reduced seizure risk compared with glass taps. This supports reliable leak resistance, stable drop formation, and consistent control near the endpoint, which is especially important for Class A volumetric work. Class A burettes are manufactured to tighter tolerance limits than Class B ware, making them suitable for analytical methods requiring higher accuracy, standardisation, and compliance driven reporting.
Supplied by LabChoice Australia, this Class A straight bore burette with PTFE key stopcock is trusted across Australian universities, research institutes, environmental laboratories, and industrial QC environments for accurate titration performance, robust BORO 3.3 construction, and repeatable volumetric dispensing outcomes.
