Deflagrating Spoon
Product Code : LSK-CL-10053
Deflagrating Spoon (SKU LSK-CL-10053) is a cup on a rod that lowers chemicals into a gas jar. The rod is held by a stopper in a dished cap, so the cap covers the jar mouth while the substance burns or reacts inside. It is used in gas preparation and analysis practicals in secondary school and college chemistry. Science Lab Supplies, based in Ambala, India, is the supply point for this spoon for schools, colleges, training institutes, tender contractors and distributors.

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 the oxides formed, using Blue Litmus Paper or the papers in Test Paper Books.
- 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.
