Pipeclay Triangle
Pipeclay Triangle (Product Code: SLE/CH/100) is a heating support used in laboratories when a substance must be heated directly over a Bunsen burner. The substance, usually held in a crucible or small dish, is placed in the triangle framework, which rests across a tripod or retort ring so the flame can reach the base of the vessel. It is a routine item in school and college chemistry practicals such as heating salts, igniting precipitates and burning metals in air. It is made by Jain Scientific Equipments Pvt Ltd (ScienceLab), Ambala, as part of its school chemistry lab equipment for India and international buyers.
Key Details
| Parameter | Detail |
|---|---|
| Type | Pipeclay triangle |
| Purpose | Holding a substance in its framework while it is heated |
| Heat source | Bunsen burner |
| Suitable for | Laboratory heating work in schools, colleges and teaching labs |
| Supplied as | Individual triangle; ask us about available sizes |
Typical Use
Set the triangle on a tripod or retort ring, seat the crucible so it sits securely in the framework with part of its body below the triangle, and light the Bunsen burner beneath. Classic practicals include heating hydrated copper sulphate to drive off water of crystallisation, heating magnesium ribbon in a lidded crucible to find the formula of its oxide, and igniting a filtered precipitate to constant mass in gravimetric analysis.
Choose a triangle that matches the crucible size so the vessel neither falls through nor perches on top. Lift hot crucibles with tongs, let the triangle cool in air on a heat-resistant surface, and never plunge it into water, as sudden cooling can crack it. Flat-bottomed glassware such as beakers belongs on a wire gauze instead. Schools buying chemistry lab equipment in India usually order triangles, tripods and crucibles together as a heating set.

Frequently Asked Questions
What is a Pipeclay Triangle used for?
It holds a substance, normally in a crucible, steady in its framework while it is heated by a Bunsen burner.
What sizes are available?
Sizes are not listed on this page. Tell us the crucible sizes you use through our contact page and we will suggest a match.
Do I need a tripod as well?
Yes. The triangle rests across a tripod or a retort ring; it does not stand on its own.
Can I heat a beaker on it?
No. It is meant for crucibles and similar small vessels. Use a wire gauze under beakers and flasks.
How do I make it last longer?
Let it cool naturally after heating, avoid knocking it against hard surfaces, and replace it if it shows cracks.
Do you supply triangles in bulk for schools?
Yes. We supply institutions and distributors in India and international markets; include quantities and delivery details in your enquiry.
