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 suit 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 in a tube held by a Test Tube Holder with Handle.
- Showing luminous and non-luminous flames by opening and closing the air sleeve.
- Heating beakers on a tripod and gauze, or igniting a sample in a Croojiola (Pot) Porcelain lifted with Stainless Steel Crucible Tongs.
- 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 comprises two Bunsen burner units with integrated stop cocks, two rotatable aluminium air sleeves and a gas flow calibration and safe operating guide. Gas hose, tripods and gauzes can be added to the same quotation; the gas supply itself is arranged by the laboratory.
Packing, MOQ and Lead Time
Request one pair for a demonstration bench or enough sets for every student position in the laboratory. The quotation shows packing, delivery time and price for that exact quantity; rubber tubing, tripods and gauzes can go on the same quote.

Frequently Asked Questions
Which gas are these burners set up for?
The standard set-up is for natural gas, and an LPG or propane configuration can be selected to suit your laboratory. Say which gas you use 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 in Ambala, India, takes care of quotations, packing and dispatch for this set. Schools, colleges and dealers have one point of contact from the first enquiry to delivery, and tubing or tripods can join the same order.
What hose fits the inlet?
The serrated brass inlet is 8 mm across and takes flexible laboratory gas tubing of 8 mm (about 5/16 in) inner diameter. Push the tubing fully over the ribs and check it for cracks before each lesson.
