Adjustable Bunsen Burner
Adjustable Bunsen Burner (Product Code: SLE/B/13) is a laboratory gas burner used where a repeatable, finely set flame is needed, with separate controls for gas and air. A brass threaded needle valve with a rubber O-ring regulates the gas, air vents regulate the air, and a flame retainer at the top keeps the flame seated on the tube. It sits on a one-piece die-cast heavy base with a riffled nozzle and is made by Jain Scientific Equipments Pvt Ltd (ScienceLab), an OEM manufacturer, at its own factory in Ambala, India.

What Is the Adjustable Bunsen Burner Used For?
Because gas and air are set independently, the same burner can hold a small, quiet flame for gently warming an indicator solution and then open up to a hot blue cone for boiling or bending glass. The flame retainer helps stop the flame lifting off the tube at higher gas settings, which makes the burner more forgiving in draughty rooms and during quick changes of flame size. College, school and quality-control labs value that repeatability.
Place it beneath a tripod and gauze, or under a flask clamped to a retort stand for distillation and reflux set-ups. Push the burner tubing well over the riffled nozzle, set the needle valve before lighting, and let the burner cool before moving it by the base. As a piece of science apparatus from an Indian manufacturer, it suits both teaching benches and routine college work.
OEM Manufacturer
ScienceLab is the trading name of Jain Scientific Equipments Private Limited, the OEM (original equipment manufacturer) of this adjustable burner. The company makes it at its own licensed factory at Saha, Ambala, Haryana, India, and supplies it factory-direct to schools, colleges, quality-control labs, dealers and importers. Because the maker handles enquiries itself, requests for seals, spare parts or repeat batches can simply be sent to us. Background on the company is on our company profile.

Frequently Asked Questions
What makes the Adjustable Bunsen Burner adjustable?
Both inlets of the Adjustable Bunsen Burner (SLE/B/13) can be set: gas through the brass threaded needle valve and air through the air vents. Flame size and flame temperature can therefore be adjusted separately for each task.
What does the flame retainer on the Adjustable Bunsen Burner do?
The flame retainer sits at the top of the Adjustable Bunsen Burner tube and helps keep the flame anchored there. It reduces the chance of the flame lifting off or going out at higher gas flow or in a draughty room.
Why is there a rubber O-ring on the needle valve?
On the Adjustable Bunsen Burner, the rubber O-ring works with the brass threaded needle valve to seal the gas regulation, so gas is metered through the valve rather than escaping around the thread. If a seal ever needs replacing, ask us.
Will standard burner tubing fit the Adjustable Bunsen Burner?
Yes. Push-on burner tubing grips the riffled nozzle of the Adjustable Bunsen Burner. Our Burner Tubing is offered in several lengths, so choose the one that reaches from the gas tap to the burner without stretching.
Is a calibration certificate available for this burner?
The Adjustable Bunsen Burner is a heating appliance rather than a measuring instrument, so it is not calibrated. If your purchasing process asks for particular documents, discuss them with us through the contact page when you request a quotation.
Who manufactures the Adjustable Bunsen Burner?
Jain Scientific Equipments Pvt Ltd, trading as ScienceLab, is the OEM manufacturer of the Adjustable Bunsen Burner. It is made at the company's own licensed factory at Saha, Ambala, Haryana, India, and bulk or export orders are quoted directly by the manufacturer.
