Burette with Glass Stopcock – 50 ml

The Burette with Glass Stopcock is laboratory glassware used to deliver measured volumes of liquid during titration and volumetric analysis. Supplied by Elmo Agencies, a manufacturer in Ambala, it is suitable for school, college, analytical, and research chemistry laboratories.

A Burette with Glass Stopcock provides controlled delivery of a titrant, allowing liquid to be added gradually during a titration until the required endpoint is reached. Its graduated tube allows the volume delivered to be determined from the difference between the initial and final readings.

Key Features

• 50 ml capacity with clear graduations
• Durable borosilicate glass construction
• Glass stopcock for controlled liquid flow
• Suitable for dropwise addition near the titration endpoint
• Useful for acid–base and redox titrations
• Suitable for chemistry laboratory practicals
• Supplied by Elmo Agencies

Applications

• Acid–base titrations
• Redox titrations
• Volumetric analysis
• Solution standardization
• Chemistry practicals
• Analytical laboratory work

How It Is Used

The burette is filled with the required titrant and the initial reading is recorded. The stopcock is then used to control the flow into the receiving flask. Near the endpoint, the titrant can be added drop by drop. The final reading is recorded, and the volume delivered is calculated from the difference between the readings.

Important Precautions

• Check the glassware and stopcock for damage or leakage before use.
• Remove air bubbles from the delivery tip before taking readings.
• Read the meniscus at eye level.
• Clean the burette properly after use.
• Ensure the glass stopcock operates smoothly.

Conclusion

The Burette with Glass Stopcock by Elmo Agencies is a practical instrument for controlled liquid delivery and titration work. Its borosilicate glass construction and glass stopcock make it suitable for volumetric analysis, chemistry practicals, and laboratory applications.
