Burette, Schellbach Stripe, PTFE Key Stopcock, Borosilicate, 50ml, Each

The 50ml Burette with Schellbach Stripe and PTFE Key Stopcock is designed for precise liquid delivery, meeting DIN ISO 385 and USP standards.

Manufactured from Borosilicate 3.3 glass (ASTM E-438, Class A, Type 1), this burette features excellent chemical resistance and heat durability. The blue-printed graduations and Schellbach stripe assist in achieving highly accurate meniscus readings.

Material & Calibration

Each burette is manufactured using precision bore tubing to ensure consistent accuracy. Calibrated to deliver (TD, EX) at 20°C, the burettes are produced on computer-controlled machines and undergo stringent quality checks.

Design Features

The burette's design includes a narrow cylindrical tube with a stopcock at one end and a tapering tip at the other. The printed graduations indicate the volume delivered when filled up to the marked point.

Each burette specifies the nominal volume, tolerance, precision class, and manufacturing standard. The Schellbach stripe allows for easy and precise reading of the meniscus, improving titration accuracy.

Applications

Primarily used in titration, the burette allows for the controlled addition of a reactant until the precise end point of a reaction is reached. Its precision makes it suitable for a wide range of laboratory applications where exact volume measurements are critical.

Autoclaving

The burette may be sterilised in an autoclave without affecting its volumetric accuracy. A standard autoclave cycle of 15 minutes at 121°C is sufficient for sterilisation purposes.
