Automatic Burette Clear Glass Stopcock is manufactured from pre-vacuum calibrated borosilicate 3.3 glass tubing in accordance with DIN/ISO Class AS standards, ensuring exceptional accuracy, chemical resistance, and long-term stability in volumetric analysis. Its precision construction is designed for fast, repeatable, and highly accurate dispensing in analytical laboratories.

The burette is equipped with an intermediate glass stopcock, allowing smooth and precise flow control for rapid titration without compromising measurement accuracy. A clearly visible Schellbach stripe is integrated into the burette body, enabling easy and precise observation of the meniscus line, even under varying lighting conditions.

All inscriptions and nominal volume values are printed with durable blue enamel, providing excellent contrast and long-lasting readability. This automatic burette is supplied without bottle and bellows; compatible bottles and bellows must be ordered separately to complete the system.

This instrument is ideal for chemical, pharmaceutical, research, and educational laboratories where precision, efficiency, and compliance with international standards are essential.
