Description
Amber Burette with PTFE Stopcock, Class B Accuracy, BORO 3.3 is designed for dependable titration and routine volumetric dispensing where light protection, smooth flow control, and chemical resistance are important. The amber borosilicate body reduces UV and visible light transmission, helping protect light sensitive titrants and analytical reagents from photodegradation. This supports better concentration stability and more consistent endpoints during day to day titration work in teaching, research, and quality control laboratories.
Manufactured from high quality LabChoice BORO 3.3 borosilicate glass, the burette offers excellent thermal stability, low thermal expansion, and strong resistance to a wide range of acids, alkalis, salts, and many solvents used in volumetric analysis. BORO 3.3 glass performance aligns with recognised standards such as ISO 3585 and ASTM E438 Type I, supporting dependable durability and chemical performance under routine laboratory handling. The Class B accuracy specification is well suited to routine titrations where good precision is required without the tighter tolerances of Class A ware.
Fitted with a PTFE stopcock, the burette provides smooth, controlled delivery and broad chemical compatibility, reducing seizure risk and improving leak resistance compared with all glass taps. This makes it practical for frequent use and for titrants that may cause glass taps to bind. Clear graduation markings support accurate meniscus reading, and smooth internal surfaces help minimise residue retention and simplify cleaning between runs. For best practice, condition the burette with the titrant, remove air bubbles from the tip, and read at eye level to improve repeatability.
Supplied by LabChoice Australia, this amber Class B burette with PTFE stopcock is widely used across Australian schools, universities, research institutes, and industrial laboratories where reliable titration performance, light protection, and robust BORO 3.3 construction are required.
