Burette 50ml – Class B Blue PTFE Stopcock (Pyrex) – Brown Packing

The 50 mL Class B burette with a PTFE stopcock from Pyrex is designed for precise liquid measurement in laboratory settings. Here are the detailed specifications and features:

1. Material and Construction:
   • Made from high-quality borosilicate glass (Boro 3.3), which is known for its durability and resistance to chemicals and thermal stress.
   • Features blue graduations that are chemically resistant, providing clear and easy-to-read measurements.
2. Capacity and Graduation:
   • The burette has a capacity of 50 mL.
   • Graduations are marked in 0.1 mL intervals, allowing for precise measurement.
   • The tolerance of the measurements is ±0.10 mL, adhering to Class B accuracy standards as per DIN ISO 385.
3. Stopcock:
   • Equipped with a PTFE (Polytetrafluoroethylene) stopcock, which ensures a smooth, leak-proof operation. PTFE is chemically resistant and provides a long service life.
   • The stopcock is a straight bore design, facilitating easy and controlled dispensing of liquids.
4. Design Features:
   • The burette has a height of approximately 75 cm, with the tube diameter being about 15 mm, making it compatible with standard laboratory setups.
   • It comes packaged in brown packing for safe transportation and storage.

These features make the burette suitable for various titration and volumetric analysis applications in both educational and professional laboratory environments.
