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. It suits distillation, reflux and solution heating in school, college and training laboratories. Science Lab Supplies sends it out from Ambala, India, on quotations for schools, colleges, training institutes, tender contractors and distributors.
Specifications
Each specification of the 500 ml flask heater is set out below. In short, a compact, cylindrical insulated body finished in white carries a blue rim that secures a form-fitting woven glass-yarn basket with built-in resistance wiring, while glass-yarn insulation and energy regulators keep the heat even and controlled.

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, with the liquid temperature checked on a Thermometer (with no Mercury).
Use it only on a dry bench with the supply voltage confirmed on the quotation, 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. A 500 ml flask, condenser and support stand can be added to the same quotation, together with any optional accessories you need for the assembly.
Packing, MOQ and Lead Time
You can request 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. State your mains voltage and plug type in the message you send from the contact page, or note it beside the heater in the enquiry cart; bid paperwork is handled through the lab tender page.
Frequently Asked Questions
What size of flask does this heater take?
It is made for a 500 ml flask, and the inner sizes are 170 x 170 x 90. 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, reducing hot spots and thermal shock. A Laboratory Spirit Burner under a Wire Gauze suits open-flame work, but the mantle keeps flames away from flammable liquids.
Who supplies the Flask Electric Heater?
Science Lab Supplies in Ambala, India, can dispatch it as a single unit or as a full laboratory set, and it can be quoted on one order with the matching flasks, condensers and clamps.
What supply voltage does the heater use?
The supply voltage is confirmed on the quotation. Give your mains voltage and plug type through the contact page, and we will confirm a suitable unit before you place the order.
