Flask Electric Heater
Product Code : SCL-CL-11913
Flask Electric Heater (SKU SCL-CL-11913), also known as a heating mantle, is a single-position electric heater that wraps a 500 ml flask in a woven glass-yarn basket for even, flame-free heating. Chemistry teachers and lab technicians use it for distillation, reflux and solution heating. Schools, colleges, training institutes, tender contractors and distributors can obtain it from Science Lab Supplies, which supplies it from Ambala, India.
Specifications
The heater has a compact, cylindrical insulated body finished in white with a blue rim that holds a form-fitting woven glass-yarn basket. Electrical resistance wiring is built into the flexible basket, so it surrounds the flask directly, while glass-yarn insulation and an energy regulator control the heat.

Applications and Experiments for the Flask Electric Heater
Because the basket envelops the flask, heat reaches the glass evenly and without the hot spots and thermal shock that an open burner flame can cause. That makes the mantle suited to distillation and reflux of flammable organic liquids, where a naked flame on the bench should be avoided.
- Class 11–12 chemistry: simple distillation and purification of liquids in a 500 ml flask.
- B.Sc. organic chemistry practicals: refluxing reaction mixtures and heating under a condenser.
- Preparing or concentrating solutions where controlled, flame-free heating is required.
Use it only on a dry bench with the correct mains supply, never switch it on without a flask in place, and let it cool before handling; students should work under supervision.
Standard Scope of Supply
The Flask Electric Heater is supplied as a single unit as described above, with its insulated body, glass-yarn heating basket and energy regulator. The 500 ml flask, condenser and support stand are separate items; any optional accessories are listed on the quotation.
Packing, MOQ and Lead Time
Order one mantle for a demonstration bench or a set for every student group. The quotation shows the packing, delivery time and price for that number of heaters, and flasks, condensers and stands can be added to equip a laboratory distillation apparatus in India in one order.
Science Lab Supplies is a registered exporter with an Importer-Exporter Code and can ship to buyers in Bangladesh, Zambia, Rwanda, South Africa, Qatar and Sri Lanka. Please mention your mains voltage when you use the contact page or enquiry cart; institutional buyers can also consult the lab tender page.
Frequently Asked Questions
What size of flask does this heater take?
It is made for a 500 ml flask. The woven glass-yarn basket fits closely around the flask so that heat is applied evenly over its surface.
Why use a heating mantle instead of a burner?
The basket heats the flask directly without a flame, which reduces hot spots and the risk of thermal shock to the glass, and keeps open flames away from flammable liquids during distillation or reflux.
Who supplies the Flask Electric Heater?
It is supplied by Science Lab Supplies from Ambala, India, for single units or full laboratory sets along with matching glassware.
What mains voltage does the heater use?
The listing does not state a voltage, so please give your supply voltage and plug type through the contact page and we will confirm a suitable unit on the quotation.
Related Distillation and Heating Equipment
A heating mantle is one part of a glassware assembly. These four items from the Chemistry Lab range complete a distillation or reflux set-up around the heater, from the flask it holds to the condenser and support, and they can be quoted together.
- Round-bottom Flask — the vessel the mantle heats.
- Liebig Condenser for Distillation of Water — cools and collects the distillate.
- Laboratory Retort Stand — clamps the flask and condenser in position.
- Magnetic Heating Stirrer — an alternative for heating and stirring solutions in beakers.
