Laboratory Burette with Rota Stopcock 50ml Manufacturer,Supplier and Exporter in India

Product Code : SCL-B-12586

The 50mL Rota Stopcock Burette is a Class B borosilicate glass burette used for controlled delivery of liquid reagents during titration and volumetric analysis. It is suitable for school chemistry labs, college laboratories, analytical practicals, laboratory technicians, distributors, and institutional procurement buyers.

Product Description

Laboratory Burette with Rota Stopcock 50ml from School Equipments India is based on the verified official listing for Glass Burette (Class B) - 50ml. The listed burette is made from clear borosilicate glass and is highly resistant to chemical attack.

The verified model has 50 mL capacity, 0.1 mL graduations, 0.1 mL tolerance, blue graduations, and an interchangeable PTFE stopcock. The official page describes the PTFE stopcock as providing excellent flow control without lubrication. The term “Rota Stopcock” should be confirmed against the final catalogue name before publication.

Key Features

• 50 mL verified capacity: suitable for common titration and volumetric-analysis work.
• Class B burette: verified classification for routine school and college laboratory use.
• Borosilicate glass body: supports chemical resistance for compatible laboratory reagents.
• 0.1 mL graduations: allows controlled reading during titration end-point work.
• 0.1 mL tolerance: verified tolerance value for the listed 50 mL burette.
• Interchangeable PTFE stopcock: supports smooth flow control without lubrication.
• Blue graduations: improves visibility during meniscus reading and classroom demonstrations.

How to Use the Laboratory Burette with Rota Stopcock 50ml

1. Inspect the burette for cracks, blocked tip, faded graduations, or stopcock damage.
2. Mount the burette vertically using a suitable burette clamp and stand.
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 to zero or record the initial burette reading at eye level.
6. Open the PTFE stopcock gradually 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 suitable PPE and follow the SDS when using acids, alkalis, oxidising agents, or other hazardous titration reagents.

Care & Maintenance

• Rinse immediately after use to prevent residue or crystallisation in the tip.
• Do not use hard wire unless the burette is blocked and the laboratory SOP permits careful clearing.
• Store vertically in a burette rack to protect the tip and stopcock.
• Check stopcock movement, graduation clarity, and tip flow before every titration session.
