Burettes Detachable Stopcock
Burettes Detachable Stopcock (Product Code: SLE/GBu/05) are graduated borosilicate glass burettes whose PTFE key stopcock can be taken off the body, so the barrel, jet and key can be washed and dried separately. They suit teaching laboratories, college chemistry departments and quality-control benches that run titrations daily and want glassware that is easy to strip down and look after. The burettes are produced by Jain Scientific Equipments Pvt Ltd (ScienceLab), Ambala, for buyers of school chemistry lab equipment in India and abroad.

Typical Use
These burettes are used for volumetric analysis in the usual way — mounted vertically, filled with standard solution and read before and after delivery — but their real benefit shows at the end of the session. Coloured or reactive titrants can leave deposits in the stopcock bore, and with a fixed stopcock that area is hard to reach. Detaching the stopcock lets a technician clean the barrel with a brush, soak the key and jet separately, and let every part drain fully before storage.
When reassembling, seat the key squarely, fill the burette with water and leave it closed for a short time to confirm there is no drip at the jet before issuing it to students. Storing the stopcock loosened or removed during long breaks also helps prevent the key from sticking.

Frequently Asked Questions
Why choose a detachable stopcock?
It can be removed from the burette, so the stopcock and bore are easier to clean, inspect and dry than on a fixed design.
What is the stopcock key made of?
PTFE. The body of the burette is heavy-duty borosilicate glass.
How do I check for leaks after refitting the stopcock?
Fill with water, close the key, clamp the burette upright and watch the jet for a few minutes. If it drips, reseat the key and test again before use.
Can I buy spare stopcocks separately?
Spare parts are not listed on this page. Please contact us with the burette size and we will advise.
Which sizes are made?
5 ml, 10 ml, 25 ml, 50 ml and 100 ml capacities are available, all graduated.
What about warranty and breakage in transit?
Please ask about warranty and transit-breakage terms when you request a quotation, so they are agreed in writing for your order.
Do you handle large and overseas orders?
Yes, we supply schools, colleges and distributors across India and international markets.
