Product Details
Our Professional Glass Burette Series is meticulously manufactured from high-quality Borosilicate 3.3 glass, offering superior chemical resistance and high transparency for precise volumetric analysis. This series includes both Acid Burettes (equipped with glass or PTFE stopcocks) and Alkali Burettes (with rubber tubing and glass bead), designed to meet the diverse titration requirements of analytical chemistry labs. With permanent, high-contrast graduations and a precision-engineered leak-proof stopcock, these burettes ensure the highest level of accuracy and reliability in measuring liquid volumes during critical titration procedures.

Product Features
High Borosilicate 3.3 Glass: Features excellent thermal stability and superior resistance to corrosive acids, alkalis, and organic solvents.
High Transparency & Clarity: Crystal-clear glass body allows for unobstructed meniscus observation and easy monitoring of liquid levels.
Precision Graduations: Uniform and permanent markings are fired into the glass surface, ensuring they remain clear and wear-resistant for accurate, long-term readings.
Leak-Proof Stopcock Design: The precision-ground glass or PTFE stopcocks provide a tight, secure seal, preventing leaks and allowing for smooth, controlled dispensing.
Smooth Inner Walls: The interior surface is expertly finished to ensure optimal liquid flow and minimal residue, enhancing measurement accuracy.
Amber Glass for UV Protection: The amber-colored version is specifically designed to shield light-sensitive reagents (like silver nitrate) from UV degradation.
Complete Range of Types: Available in Acid (Acid-base titration) and Alkali (Basic solution titration) configurations to suit all laboratory protocols.
