Bunsen Burner with Stopcock
Bunsen Burner with Stopcock (Product Code: SLE/B/11) is a Bunsen gas burner used for general laboratory heating, with a stopcock fitted in its inlet tube so the gas flow can be controlled at the burner itself. It follows the design of our SLE/B/10 Bunsen Burners, letting teaching and research labs pause or fine-tune the flame without reaching back to the bench tap. It is made by Jain Scientific Equipments Pvt Ltd (ScienceLab), an OEM manufacturer, at its own factory in Ambala, India, among its chemistry lab instruments.

What Is the Bunsen Burner with Stopcock Used For?
With the stopcock on the inlet, gas can be turned down between steps of an experiment, for example while a student reads a thermometer or changes a test tube, and turned back up without disturbing the connection at the tap. That is convenient in fume cupboards where the outlet is at the back, on long benches where several burners share one supply, and in practicals that alternate short heating periods with observation.
In every other respect it is used like a standard Bunsen burner: connect the tubing, open the bench tap, light the burner, then set the flame with the stopcock and the air regulator. Always close the bench tap as well as the stopcock at the end of the session so the tubing is not left under pressure.
OEM Manufacturer
ScienceLab is the brand under which Jain Scientific Equipments Private Limited sells the burners it makes, and the company is the OEM (original equipment manufacturer) of this stopcock model. It is produced at the company's own licensed factory at Saha, Ambala, Haryana, India, and supplied factory-direct to schools, colleges, dealers and importers, so a lab can standardise on matching SLE/B/10 and SLE/B/11 burners from one maker. For spares or repeat orders, simply ask us. Company background is on our profile page.

Frequently Asked Questions
How is the Bunsen Burner with Stopcock different from the SLE/B/10 burner?
The Bunsen Burner with Stopcock (SLE/B/11) follows the SLE/B/10 Bunsen burner design but has a stopcock fitted in the inlet tube. That stopcock lets the user control or pause the gas flow at the burner rather than at the bench tap.
Where can I find the dimensions of the Bunsen Burner with Stopcock?
The Bunsen Burner with Stopcock follows the dimensions and construction of the SLE/B/10 model shown on the Bunsen Burners page. Contact us if you need those figures confirmed in writing on your quotation.
Can I rely on the stopcock instead of the bench tap?
No. On the Bunsen Burner with Stopcock, use the stopcock for adjusting and pausing the flame, but always shut the bench tap at the end of work as well, so the tubing between tap and burner is not left under gas pressure.
What should I do if the stopcock becomes stiff?
Do not force the stopcock on the Bunsen Burner with Stopcock or apply ordinary oil. Once the burner is cool, clean off any residue around the stopcock, and if it stays stiff, contact us for advice through the contact page.
Is the Bunsen Burner with Stopcock suitable for LPG?
The gas type is not specified for the Bunsen Burner with Stopcock in our product details. Tell us whether your laboratory uses natural gas or LPG so we can confirm the right configuration before the burners are dispatched.
