Description
Rotaflow Burette with PTFE Stopcock, Class B BORO 3.3 is designed for controlled liquid dispensing in titration, volumetric measurement, and routine laboratory analysis. Made from BORO 3.3 borosilicate glass, this burette provides reliable chemical resistance, thermal stability, and durability for regular laboratory handling. The Class B accuracy rating makes it suitable for general laboratory, school, university, and training applications where dependable volumetric performance is required.
The PTFE stopcock supports smooth flow adjustment and controlled reagent delivery, helping users manage titration procedures with better handling and flow consistency. Its rotaflow design allows convenient operation during acid-base titration, reagent dispensing, and standard chemistry practical work. This makes the burette a practical choice for education laboratories, quality control areas, and routine testing environments.
For quality alignment, this burette is relevant to recognised laboratory glassware standards such as ISO 385 for burettes, ISO 3585 for borosilicate glass 3.3 properties, ASTM E287 for laboratory glass graduated burets, and ASTM E438 for glass used in laboratory apparatus. ISO 385 covers metrological and construction requirements for burettes, while ASTM E287 covers precision and general-purpose glass burets, including Class B general-purpose burets. ISO 3585 defines borosilicate glass 3.3 properties for laboratory glassware, and ASTM E438 is commonly referenced for laboratory apparatus glass quality.
BORO 3.3 glass is widely selected for laboratory glassware because it offers strong resistance to chemical exposure and thermal stress compared with ordinary glass. For laboratories requiring formal compliance, calibration certificates, batch certificates, or Class A tolerance requirements, documentation should be checked before purchase, as this product is supplied as a Class B burette based on the provided product specification.
LabChoice Australia supplies this Rotaflow Burette with PTFE Stopcock for Australian laboratories, schools, and science teaching facilities that need reliable BORO 3.3 glassware for titration and controlled liquid measurement. Its combination of borosilicate glass construction, PTFE stopcock control, and Class B grading makes it a practical option for everyday chemistry workflows.
