Deflagrating Spoon
Product Code : LSK-CL-10053
Deflagrating Spoon (SKU LSK-CL-10053) is a small cup on a long rod that lowers a burning or reacting substance into a gas jar. The rod passes through a stopper set in a dished cap, so the cap closes the jar mouth while the reaction takes place inside. It is used in gas preparation and analysis practicals in secondary school and college chemistry. Science Lab Supplies sends the spoon from Ambala, India to schools, colleges, training institutes, tender contractors and distributors.
Specifications
The spoon measures 35 cm overall. A 20 mm diameter cup at the lower end carries the sample, and the rod is held by a stopper in a 75 mm diameter dished cap that rests over the neck of a standard gas jar, letting the cup height be set before lowering.

Applications and Experiments for the Deflagrating Spoon
The deflagrating spoon is used to burn elements in jars of collected gas and to compare how they react. A small amount of a substance is heated in the cup, then lowered into the jar, and students record the flame, the products formed and, where relevant, their effect on moist litmus.
- Class 8 and 10 science: burning metals and non-metals to form oxides.
- Class 11 chemistry: properties of oxygen and other prepared gases.
- Testing the acidic or basic nature of oxides formed by combustion.
- Teacher-training labs: standard gas-jar demonstrations.
Burning substances such as sulphur produce toxic fumes, and the cup and rod become very hot. Carry out these experiments in a fume cupboard or well-ventilated room, wear eye protection and keep them under teacher supervision.
Standard Scope of Supply
One Deflagrating Spoon is supplied, comprising the cup, rod and stopper fitted in the dished cap. Gas jars, burners and the chemicals to be burned are not included; they can be requested on the same quotation.
Packing, MOQ and Lead Time
Whether you need one spoon for the teacher's bench or one per practical group, the quotation will state packing, delivery time and price for that number. Gas jars, beehive shelves and other chemistry lab equipment in India can be quoted with it.
Science Lab Supplies is registered with an Importer-Exporter Code, so it can ship to buyers in Iraq, Nigeria, Kenya, Ghana, Ethiopia and Tanzania. Write to the team via the contact page, put the spoon in the enquiry cart, or see the lab tender page for tender supply.
Frequently Asked Questions
What is a deflagrating spoon used for?
It holds a small amount of a substance in its cup and lowers it into a gas jar, so students can watch it burn or react in the collected gas while the cap covers the jar.
What are its dimensions?
The spoon is 35 cm long, the cup is 20 mm in diameter and the dished cap is 75 mm in diameter.
Who supplies the Deflagrating Spoon?
Science Lab Supplies supplies it from Ambala, India, and can quote it together with gas jars and gas-preparation apparatus.
Can the cup height be adjusted?
Yes. The rod is held by a stopper in the cap, so it can be slid to set how deep the cup sits inside the jar.
