Description
Burette with Straight Bore and PTFE Key Stopcock, Class B Accuracy is designed for reliable volumetric dispensing in titration and routine analytical work where smooth flow control, clear readings, and chemical resistance are essential. The straight bore construction supports consistent, predictable delivery, improving endpoint control in acid base titrations, redox titrations, complexometric titrations, and general quantitative dosing across teaching laboratories, research benches, and industrial QC environments.
Manufactured from high quality LabChoice BORO 3.3 borosilicate glass, the burette provides excellent thermal stability, low thermal expansion, and strong 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 dependable durability and chemical performance under daily laboratory handling. The graduated scale is designed for clear meniscus visibility and repeatable readings, while the Class B accuracy specification is well suited to routine titration work where good precision is required without the tighter tolerances of Class A ware.
The integrated PTFE key stopcock delivers smooth, controlled flow with strong chemical compatibility, reducing seizure risk and improving leak resistance compared with all glass taps, especially when used frequently or with aggressive reagents. This supports consistent dropwise control near the endpoint, improved operator confidence, and cleaner operation with reduced maintenance.
Supplied by LabChoice Australia, this Class B straight bore burette with PTFE key stopcock is widely used across Australian schools, universities, research institutes, and industrial laboratories for dependable titration performance, robust chemical resistance, and repeatable volumetric dispensing.
