Application
Glass burettes are precision instruments used for:
- Titration in volumetric analysis
- Accurate dispensing of measured liquid volumes
- Acid–base, redox, and complexometric titrations
- Routine analytical work in chemical, dairy, petroleum, pharmaceutical, and educational laboratories
Compliance Standard
- ISO 385 – Laboratory glassware, burettes
- ASTM E287 – Standard specification for glass burettes
- Class A / Class B accuracy
- Manufactured from Borosilicate Glass 3.3
Product Description
Burettes are made from high-quality Borosilicate Glass 3.3 with a uniform bore for precise flow control. They are fitted with a leak-proof PTFE key stopcock or glass stopcock for smooth operation. Clear, permanent graduations in white enamel ensure easy and accurate reading.
The burette is designed for controlled delivery of liquids during titration with high chemical and thermal resistance.
