Deflagrating Spoon and Cap

Product Code : LSK-CL-10237

Deflagrating Spoon and Cap (SKU LSK-CL-10237) is a 35 cm combustion spoon: a steel cup on a steel rod, held by a cork in an aluminium cap that sits over the mouth of a gas jar. Teachers use it to lower a burning substance into a jar of oxygen or another gas in secondary and senior-secondary chemistry. It reaches buyers through Science Lab Supplies in Ambala, India, which supplies schools, colleges, tender contractors and distributors.

Specifications

Every measurement of the 35 cm deflagrating spoon has its own row below. In short, an 18 mm steel cup sits on a steel rod, and a cork holds the rod in a 90 mm aluminium cap that covers the gas jar, so the gas stays inside during burning.

Applications and Experiments for the Deflagrating Spoon and Cap

The spoon carries a burning element into a gas jar so students can see how it burns in pure oxygen compared with air, then test the oxide formed. The cap keeps the gas contained and lets the spoon hang at a steady height, making it a standard combustion demonstration tool.

• Class 8 science: combustion and the need for oxygen, after first confirming that the jar holds oxygen with glowing Wood Splints.
• Class 10 science (NCERT): burning a non-metal such as sulphur and testing its oxide with moist litmus to show it is acidic; a metal ribbon is instead held in Stainless Steel Crucible Tongs.
• Class 11 chemistry: reactions of elements with oxygen generated from Hydrogen Peroxide 6% Analytical Solution during gas preparation practicals.

Burning elements such as sulphur give off irritating, toxic fumes, so these demonstrations belong in a fume cupboard or well-ventilated room under teacher supervision.

Standard Scope of Supply

Each piece consists of the steel cup and rod, the cork and the 90 mm aluminium cap, supplied assembled as described above. Gas jars, a burner and the substances to be burned are not included; they can be added to the quotation together with any other combustion apparatus you need.

Packing, MOQ and Lead Time

Whether you need one spoon for a teacher's demonstration or one per student group, Science Lab Supplies quotes for that quantity and states the packing, delivery time and price. Gas jars and burners can be listed on the same enquiry for school chemistry lab equipment in India.

With an Importer-Exporter Code as a registered exporter, Science Lab Supplies can ship to buyers in Saudi Arabia, Oman, the Philippines, Nepal, Bangladesh and Zambia. Prices for one spoon or a class set can be requested on the contact page or through the enquiry cart, while formal bids follow the steps on the lab tender page.

Frequently Asked Questions

What is the cap on a deflagrating spoon for?
The 90 mm aluminium cap rests over the mouth of the gas jar. It keeps the gas from escaping while the sample burns and holds the spoon at a fixed depth through the cork.

How does this differ from the Deflagrating Spoon (LSK-CL-10053)?
Both are 35 cm long and both close the gas jar with a cap. This model has an 18 mm steel cup on a steel rod held by a cork in a 90 mm aluminium cap. LSK-CL-10053 has a 20 mm cup, with its rod held by a stopper in a 75 mm dished cap.

Who supplies the Deflagrating Spoon and Cap?
Science Lab Supplies supplies this spoon from Ambala, India, and can add gas jars, tongs, burners and other combustion apparatus to the same quotation for a school or college laboratory.

Can it be quoted for a school tender?
Yes. Send the quantity, delivery address and tender specification, and the item-wise quotation will list this spoon with its 35 cm length and 90 mm cap.
