Flame Spreader
Flame Spreader (Product Code: SLE/B/23) is a burner-top attachment with an 18 mm top, used to turn a round burner flame into a flat, fishtail-shaped flame for glass working in chemistry and physics laboratories. It is intended for burners fitted with a flame stabilizer, and teachers and lab assistants use it when bending or shaping glass tubing for apparatus. It is made by Jain Scientific Equipments Pvt Ltd (ScienceLab), an OEM manufacturer, at its own factory in Ambala, India, alongside its chemistry lab equipment in India.

What Is the Flame Spreader Used For?
A plain burner flame heats only a short length of glass tubing, which tends to make a bend kink or flatten. With the spreader in place, the wide fishtail flame warms several centimetres of tube at once, so the glass softens evenly and can be bent into a smooth right angle or U-shape. Teachers use it to prepare delivery tubes for gas collection apparatus, bent tubes for siphon and capillary demonstrations, and jets for wash bottles.
Hold the tube along the length of the flame and roll it steadily until it sags slightly, then take it out of the flame and bend it in one smooth movement. Place finished pieces on a heat-resistant mat to cool, and remember that the spreader itself stays hot for some time after the gas is turned off.
OEM Manufacturer
ScienceLab is the brand of Jain Scientific Equipments Private Limited, the OEM (original equipment manufacturer) that makes the Flame Spreader at its own licensed factory at Saha, Ambala, Haryana, India. Schools, colleges, institutions and dealers therefore buy this small accessory from its maker, and can ask the same team whether it suits burners they already own. For purchase departments that register vendors, the company's GSTIN is 06AAECJ8618A1ZT and its Legal Entity Identifier (LEI) is 3358004HRD1JIVXKYX49. Further background is on our company profile.

Frequently Asked Questions
What does the Flame Spreader do?
The Flame Spreader reshapes a burner's round flame into a flat fishtail flame. This spreads the heat along a longer section of glass tubing, so the glass softens evenly and can be bent or shaped without kinking.
Will the Flame Spreader fit my existing burner?
The Flame Spreader has an 18 mm top and is intended for burners with a flame stabilizer. Because burner tubes vary, send us your burner details through our contact page and we will confirm the fit before you order.
Can I heat beakers or flasks with the Flame Spreader fitted?
The Flame Spreader is meant for glass working rather than general heating. For warming beakers or flasks, remove it and use the normal burner flame with a tripod and wire gauze, which spreads heat more safely under glassware.
Which glass tubing is easiest to work with the Flame Spreader?
Soft soda-glass tubing is the usual choice for bending with the Flame Spreader in a burner flame. Borosilicate tubing softens at a much higher temperature and may need a hotter flame, so ask us if you are unsure which tubing to order.
How should the Flame Spreader be handled after use?
Turn off the gas and allow the Flame Spreader to cool fully before lifting it off the burner, or use tongs if it must be removed while still warm. The attachment stays hot for some time after the flame is out.
Who manufactures the Flame Spreader?
The Flame Spreader is manufactured by Jain Scientific Equipments Pvt Ltd (ScienceLab), the OEM, at its own factory in Saha, Ambala, Haryana, India. Quotations and repeat orders are handled directly by the manufacturer, which can also advise on burner compatibility.
What details should we send for a Flame Spreader quotation?
For a Flame Spreader quotation, tell us the quantity, the burners you will use it with, and the delivery address in India or abroad. Bulk supply to schools, colleges and distributors is available on request.
