How to Use the Analytical Burette with Glass Stopcock 50ml

1. Inspect the burette for cracks, blocked tip, faded graduations, or stopcock damage.
2. Mount the burette vertically on a stable stand using a suitable burette clamp.
3. Rinse the burette with a small volume of the titrant before filling.
4. Fill above the zero mark and remove air bubbles from the tip.
5. Set the meniscus at zero or record the initial reading at eye level.
6. Open the glass stopcock carefully to deliver titrant into the receiving flask.
7. Slow the flow near the end point and add drops carefully.
8. Record the final reading and calculate the delivered volume.

Safety note: Use only under trained supervision. Wear PPE and follow the SDS when handling acids, alkalis, oxidising agents, solvents, or other hazardous titration reagents.

Care & Maintenance

• Rinse immediately after use to prevent crystallisation or blockage in the tip.
• Keep the glass key clean and correctly seated for smooth flow control.
• Do not force a stuck stopcock; release it using approved laboratory procedure.
• Store vertically in a burette rack to protect the tip, scale, and stopcock.
