What Is the Bunsen Burner with a Spare Jet Used For?
It does everything a standard teaching-lab burner does: heating liquids in test tubes and beakers over a tripod and gauze, flame tests on metal salts, warming solutions for reactions, and sterilising wire loops and the mouths of culture tubes in microbiology practicals. The sleeve air regulator lets students compare the yellow, luminous flame of a closed air hole with the hotter blue flame of an open one.
The jet is the narrowest part of the gas path, and soot, boiled-over liquid or careless cleaning can block or damage it, giving a weak, flickering or lifting flame. Clear a dirty jet gently without enlarging the hole, or fit the spare and keep the old one for cleaning. When lighting, close the air sleeve, hold the flame ready, then open the gas tap; since there is no regulator on the burner, adjust and shut off the gas at the tap and never leave the burner alight unattended.
What to Specify When Ordering
- Gas type — LPG or natural gas, so both the fitted jet and the spare suit your supply.
- Quantity — the minimum order is 10 units, each with its spare jet.
- Model mix — add burners with a gas regulator if some benches need control at the burner.
- Accessories — burner tubing, tripod stands and gauzes for complete heating stations.
Frequently Asked Questions
What does the spare jet do?
It replaces the fitted jet if that one becomes blocked or damaged, so the burner can go straight back into use. One spare jet is supplied with each burner.
How is this different from the standard brass-pipe Bunsen burner?
The burner itself has the same listed build — 12 mm brass chrome-plated tube, cast iron base, sleeve air regulator and no gas regulator — and this version adds the spare jet.
Does the burner have a gas regulator?
No. The ribbed gas inlet has no regulator, so the gas is controlled at the laboratory tap. Choose the gas-regulator model if you need a stopcock on the burner.
Which gas does it run on?
The listing does not state the gas type. Specify LPG or natural gas in your enquiry, since the jet size depends on the gas.
Who manufactures it?
JLab, the trading name of Jain Laboratory Instruments Pvt Ltd, makes this burner at its Ambala works in Haryana, India, and supplies it factory-direct.
OEM Manufacturer
JLab is the trading name of Jain Laboratory Instruments Pvt Ltd, a maker of laboratory heating apparatus and school science equipment in India, incorporated in 2017 and based on Hargolal Road, Ambala, Haryana. The burner and its spare jet are produced at JLab’s own works, not bought from a trader, so schools, colleges, dealers and importers order directly from the manufacturer, each burner is visually checked before it is packed, and further jets or repeat orders come from the same source. JLab holds MSME Udyam registration UDYAM-HR-01-0003849 as a manufacturing enterprise and Importer-Exporter Code 3317504552. JLab exports worldwide and ships to buyers in every region — for example Ecuador in South America, Myanmar in Southeast Asia, Guatemala in Central America and the Caribbean, Congo in Central Africa and France in Western Europe.
