What Is a Porcelain Triangle Used For?
A pipeclay triangle lets a crucible sit directly in the hottest part of a Bunsen flame. Typical uses are heating a substance to constant mass, driving off the water of crystallisation from copper sulphate crystals, burning magnesium ribbon to compare masses before and after, and igniting precipitates in gravimetric analysis at college level. The triangle is laid on a tripod stand or a retort ring, and the crucible should sit firmly in it without slipping through — which is why the size is chosen by crucible.
A hot triangle looks the same as a cold one, so leave it to cool on a heat-resistant mat and move the crucible with tongs. Porcelain is brittle: do not drop the triangle or cool it suddenly in water, and replace it if a tube cracks or the wire shows through.
What to Specify When Ordering
- Size — 55, 65 or 75 mm tube length; give your crucible size if you are unsure which one fits.
- Quantity per size — the minimum order is 10 units; a class set often needs one triangle per bench group plus spares.
- Temperature requirement — state your working temperature so JLab can confirm the rating.
- Crucibles, tongs and tripods — these are separate items that can join the same enquiry.
Frequently Asked Questions
Which size of porcelain triangle do I need?
Choose by crucible. The triangles come in 55, 65 and 75 mm tube lengths, and the crucible should rest firmly in the triangle without dropping through. If you are unsure, send the crucible size with your enquiry.
What temperature can the triangle withstand?
The listing states a maximum temperature of up to 800 but gives no unit. °C is the usual unit for this kind of rating; JLab confirms it in the quotation.
Is a porcelain triangle the same as a pipeclay triangle?
Yes. The listing uses both names for the same item; “pipeclay triangle” refers to the triangular frame of ceramic tubes.
How does it differ from the JLab Clay Triangle?
The Clay Triangle is listed with clay pipes on steel wire and a 2 inch (50 mm) side. This item uses unglazed porcelain tubes on twisted iron wire and comes in three tube lengths.
Are the crucible and tripod stand included?
No. This listing covers the triangle only; crucibles, crucible tongs and tripod stands are separate items, linked below.
What should I send for an export quotation?
The sizes and quantities, the destination country and port or city, preferred delivery terms such as FOB or CIF, any packing or labelling instructions, and a tender reference if there is one.
Who manufactures these triangles?
JLab (Jain Laboratory Instruments Pvt Ltd) makes them at its works in Ambala, Haryana, and quotes as the manufacturer.
OEM Manufacturer
JLab is the trading name of Jain Laboratory Instruments Pvt Ltd, a manufacturer of chemistry lab apparatus in India, incorporated in 2017 and based on Hargolal Road, Ambala, Haryana. The triangles are assembled at JLab’s own works, not bought in from a trader, so schools, colleges, dealers and importers deal directly with the maker, every triangle is checked by eye before packing, and repeat orders and spares come from the same source. JLab exports worldwide and ships to buyers in every region — for example Ethiopia in East Africa, Germany in Western Europe, Taiwan in East Asia, Sri Lanka in South Asia and Paraguay in South America. For tender purchases see the lab tenders page.
