Deflagrating Spoon and Cap
Product Code : LSK-CL-10237
Deflagrating Spoon and Cap (SKU LSK-CL-10237) is a long-handled combustion spoon: a small 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. Science Lab Supplies provides it from Ambala, India to schools, colleges, tender contractors and distributors.
Specifications
The apparatus measures 35 cm in length. Its 18 mm steel cup holds a small sample, while the 90 mm aluminium cap covers the jar so the gas stays inside during burning. The cork grips the rod, letting the depth of the cup inside the jar be set before the demonstration.

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.
- Class 10 science (NCERT): burning a non-metal such as sulphur and testing its oxide with moist litmus to show it is acidic.
- Class 11 chemistry: reactions of elements with oxygen 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 ordered separately; any optional extras are listed on the quotation.
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.

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, a laboratory equipment supplier in India based in Ambala, supplies it along with gas jars, burners and other combustion apparatus for schools and colleges.
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.
