Bunsen Burner with Stopcock
Product Code : EL-B-10668
Quick answer: The Bunsen Burner with Stopcock is a 125 mm laboratory gas burner with its own stopcock fitted in the gas inlet tube, so the gas can be turned down or shut off at the burner instead of reaching across to the bench tap. It has a nickel-plated 100 x 12 mm tube and a screwed air regulator. Lab Exports manufactures it in Delhi for school, college, research and industrial laboratories.

Why a stopcock on the burner helps
On many benches the gas tap is at the back or side of the bench, and the burner tubing runs across the work area. A stopcock on the burner's own inlet puts the gas control within easy reach of the student. The flow can be reduced for gentle warming, or shut off in one movement if something spills or boils over, while the bench tap stays open.
Air is still set with the screwed regulator at the foot of the nickel-plated tube, so the stopcock controls how much gas reaches the jet and the regulator controls how much air mixes with it. Together they let the user hold a small, steady blue flame for slow evaporation or crystallisation, then open up to a full roaring flame for boiling.
- Fit burner tubing from the bench gas tap to the riffled connector.
- Close the air regulator; open the bench tap fully and use the burner stopcock to admit gas; light it.
- Open the air regulator for a blue flame and trim the gas on the stopcock.
- At the end of the practical, close the stopcock and then the bench tap.
