A burette is a long, graduated tube with a precision control valve (stopcock) at the bottom, designed for dispensing accurate amounts of liquid in titration and chemical analysis. It is widely used in analytical chemistry, research, and educational laboratories for precise volume measurement and controlled reagent delivery.

Key Features:

• Material Options:

  • Borosilicate glass – heat and chemical resistant

  • Plastic (polycarbonate or acrylic) – shatterproof and lightweight

• Volume Sizes: Common capacities: 25 ml, 50 ml, 100 ml

• Graduations:

  • Fine, easy-to-read volume markings (typically in 0.1 ml increments)

  • Clear or amber-tinted versions available for light-sensitive reagents

• Stopcock Type:

  • Glass or PTFE (Teflon) for smooth, leak-free control

• Accuracy Class: Class A or Class B as per ISO/ASTM standards

• Mounting: Compatible with standard burette stands and clamps
