A burette is a graduated glass tube with a tap at one end, for delivering known volumes of a liquid, especially in titrations. It is a long, graduated glass tube, with a stopcock at its lower. The flow of liquid from the tube to the burette tip is controlled by the stopcock valve.

Class A burette with single straight bore. Interchangeable PTFE key stopcock with blue ceramic graduations. Accuracy as per DIN ISO 385. This unit requires no lubrication and is sealed with a simple nut and ‘O’ ring mechanism.

Key Performance Specifications
  • Compliance & Calibration: Meets DIN ISO 385 and USP (United States Pharmacopeia) standards, as well as IS 1997:2008. This makes them suitable for pharmaceutical and ISO-certified environments.
  • PTFE Key (Straight Bore): The stopcock uses a self-lubricating PTFE plug.
    • Advantage: It is completely grease-free, preventing sample contamination and ensuring the valve never "freezes" or leaks due to grease breakdown.
  • Accuracy (Class A): These instruments provide the tightest possible tolerances (e.g., ±0.05 mL for a 50mL burette).
  • Traceability: Each burette is issued with a Batch Certificate, allowing you to document the specific calibration results for your quality management system.
 
Customization Options
  • Printing Colors:
    • White/Blue: Best for clear or dark-colored liquids.
    • Amber: Often used for light-sensitive titrants to prevent degradation during the process.
  • Chemical Resistance: The Borosilicate 3.3 glass body combined with the PTFE key creates an assembly that is nearly inert to all acids, bases, and solvents.
