REILGLAS Class ‘A’ Burettes with Straight Bore PTFE Key Stopcock are engineered for accurate, repeatable, and controlled volumetric dispensing in analytical and quality-critical laboratory applications. Manufactured from high-quality, chemically resistant glass with uniform straight bore construction, these burettes ensure consistent internal diameter, smooth liquid flow, and reliable volume delivery.

The PTFE key stopcock provides excellent chemical inertness, corrosion resistance, and low friction operation, enabling precise flow regulation and long service life. The straight bore design minimizes turbulence and dead volume, ensuring stable and repeatable titration results.

All models conform to Class ‘A’ accuracy requirements as per ISO 385 / IS 1997:2008, featuring sharply etched, high-contrast graduation markings with fine subdivisions for improved readability and reduced parallax error. Each burette is individually calibrated to meet strict tolerance limits.

To accommodate different laboratory needs, these burettes are available in:

• Clear Glass – suitable for routine and general analytical titrations

• Amber Glass – recommended for light-sensitive reagents and solutions

Standard models are supplied with a Calibration Certificate, while accredited laboratories can opt for versions with NABL-traceable Calibration Certificate to ensure traceability and compliance with quality management systems.

Available capacities include 10 ml, 25 ml, 50 ml, and 100 ml, making these burettes suitable for a wide range of titration volumes in:

• Analytical and QC laboratories

• Pharmaceutical and chemical industries

• Research and academic institutions

• Environmental and food testing laboratories

REILGLAS Class ‘A’ burettes with PTFE key stopcock combine precision, chemical resistance, and certified calibration, delivering dependable performance for high-accuracy volumetric analysis.
