Crucible Tongs
Product Code : SCL-CL-11915
Crucible Tongs (SKU SCL-CL-11915) are metal scissor-action tongs for lifting crucibles, evaporating dishes and other hot containers to and from a heat source. They suit chemistry benches from school practicals to college gravimetric work wherever hot vessels must be moved safely. For schools, colleges, training institutes, tender contractors and distributors, Science Lab Supplies arranges supply of these tongs from Ambala, India, alongside other school chemistry lab equipment in India.
Specifications
The table records every specification of these 4 cm crucible tongs. In short, they are metal tongs with a scissor-like design whose handles keep the hands at a safe distance from the heat source, and whose jaws open to 4 cm to grip a crucible or small dish securely.

Applications and Experiments for the Crucible Tongs
Whenever a crucible, dish or small vessel has been heated strongly, it should be moved with tongs rather than fingers. With these tongs, students can lift crucibles off pipe-clay triangles, transfer them to a desiccator and handle hot porcelain during ignition and evaporation experiments.
- Class 9–10 science: heating magnesium ribbon or copper powder in a crucible over a Beck Bunsen and weighing the product.
- Class 11–12 chemistry: heating hydrated salts to constant mass on the Laboratory Scales Electronic to find water of crystallisation.
- B.Sc. gravimetric analysis: moving ignited crucibles between burner, furnace and desiccator.
- General lab safety training in handling hot glassware and porcelain.
Warm the tips of the tongs briefly before gripping a hot crucible; touching red-hot porcelain with cold metal can crack it through thermal shock.
Standard Scope of Supply
The Crucible Tongs are supplied as a single pair as described above, in metal with a 4 cm jaw opening. Crucibles, pipe-clay triangles and burners can be added to the same quotation if you are setting up a complete crucible-heating station for a class.
Packing, MOQ and Lead Time
A single pair or one pair per workstation can be quoted. Ask for a quotation for any quantity; it gives the packing, delivery time and price for that number of tongs, and crucibles, triangles or other chemistry lab equipment in India can be quoted in the same document.
Using its Importer-Exporter Code, Science Lab Supplies is able to ship to buyers in Rwanda, South Africa, Qatar, Sri Lanka, Vietnam and Malaysia. Pairs for each workstation can be requested on the contact page or collected in the enquiry cart with your crucibles, while schools issuing a tender can start from the lab tender page.
Frequently Asked Questions
How wide do the jaws of these tongs open?
The jaws open to 4 cm, which suits standard laboratory crucibles and small porcelain dishes. The scissor-like action lets you close the jaws firmly on the rim or body of the vessel before lifting it.
Why should the tong tips be pre-heated?
Gripping a very hot porcelain crucible with cold metal tips can make the porcelain shatter from thermal shock. Warming the tips in the flame first reduces that risk and is standard lab practice.
Who supplies these Crucible Tongs?
Science Lab Supplies handles them from Ambala, India, quoting a single pair or a class set and adding crucibles, triangles and other heating accessories to the same order where needed.
Can crucible tongs be used for other hot items?
Yes. Besides crucibles they can move small evaporating dishes and other hot containers. Heavy beakers are better handled with the Beaker Tong SS, which grips larger round vessels.
