Product Code : SCL-CL-12018
Adjustable Bunsen Gas Burner with Control Valve (Set of 2) (SKU SCL-CL-12018) is a pair of Bunsen burners, each with its own built-in stop cock, so the gas flow and flame size can be set right at the burner. They provide the main open-flame heat source in chemistry, biology and general science laboratories. Science Lab Supplies supplies the pair from Ambala, India, for schools, colleges, training institutes, tender contractors and distributors.
Specifications
Each burner has a nickel-plated brass mixing tube on a weighted die-cast zinc alloy base with a powder-coated finish. A brass needle-valve stop cock controls the gas, a rotating aluminium sleeve controls the air, and an 8 mm serrated inlet takes the gas hose.

Applications and Experiments for the Bunsen Burner
Bunsen burners heat test tubes, beakers and crucibles, sterilise tools and produce the flames used in flame tests. They appear in CBSE Class 9–12 chemistry practicals, B.Sc. inorganic and microbiology labs, and technician courses where students learn to handle laboratory gas safely.
- Class 11–12 salt analysis: flame tests for metal ions and dry-heating tests.
- Showing luminous and non-luminous flames by opening and closing the air sleeve.
- Heating beakers and flasks on a tripod and gauze.
- Microbiology: flaming loops and needles during aseptic transfer.
Check hoses for cracks, light the match before opening the stop cock, and never leave a lit burner unattended. Students should use gas burners only under supervision.
Standard Scope of Supply
The set is listed with two Bunsen burner units with integrated stop cocks, two rotatable aluminium air sleeves and a gas flow and safe operating guide. The gas hose, gas supply, tripod and gauze are not included.

Frequently Asked Questions
Which gas are these burners set up for?
The listing gives natural gas as the standard set-up. Tell us which gas your laboratory uses when you enquire so the quotation reflects it.
What does the control valve do?
The built-in stop cock adjusts or shuts the gas at the burner itself, so flame size can be set without reaching for the bench tap.
Who supplies the Adjustable Bunsen Gas Burner with Control Valve (Set of 2)?
Science Lab Supplies supplies the set from Ambala, India, and handles quotations for schools, colleges and dealers itself, so buyers have one point of contact from enquiry to dispatch.
How many burners are in one set?
Two complete burners, each with its own stop cock and air sleeve.
Related Burner Accessories
A Bunsen burner needs a gas connection and something to hold the vessel over the flame; flame tests also call for a filter glass. These four items round out a heating bench and can be priced with the burners on one quotation.
- Rubber Tube (Laboratory) — tubing to connect the burner.
- Cast Iron Tripod Stand — stands over the burner to carry glassware.
- Laboratory Wire Gauze Mesh — ceramic-centred gauze for the tripod.
- Cobalt Blue Glass (Flame Testing) — used when observing flame colours.
