Simple Appliances for Cooking Gas Lighter than Air
Product Code : SCL-CL-11462
Simple Appliances for Cooking Gas Lighter than Air (SKU SCL-CL-11462) is a test-tube set for preparing a gas less dense than air and collecting it by downward displacement of air, with "cooking" in the name meaning preparing. A straight glass tube rises from the stoppered reaction tube into an inverted collecting tube, which the light gas fills from the top. Science Lab Supplies supplies the set from Ambala, India to school and college labs, distributors and tender contractors.
Specifications
The appliance uses a test tube 18 mm in diameter and 150 mm long as the reaction vessel. A rubber stopper with a single hole holds a straight glass tube of 6 mm external diameter, which points upward so an inverted tube can be lowered over it.

Applications and Experiments for Gas Lighter than Air
The set is used to prepare and collect light gases such as hydrogen, made from zinc and dilute acid, in an inverted tube held over the outlet. Students then identify hydrogen with the squeaky pop test or compare how quickly light and dense gases escape from open tubes.
- NCERT Class 10 science: reaction of metals with dilute acids and the test for hydrogen.
- Class 11 chemistry: preparation of hydrogen and choice of collection method.
- Middle-school science: comparing the density of gases with that of air.
Hydrogen and air form an explosive mixture. Keep flames away while the gas is being generated, test only a small collected sample, and work under the supervision of a teacher with eye protection.
Standard Scope of Supply
The appliance is supplied as an 18 x 150 mm test tube, one straight 6 mm glass tube and a rubber stopper with a hole. Collecting tubes, zinc granules, acids and a stand are not part of the listing.

Frequently Asked Questions
Why is the glass tube straight?
A light gas rises, so the tube only needs to lead straight up into an inverted collecting tube. The gas collects at the top and pushes the air down and out.
Is "cooking" a translation of preparing?
Yes. The product name uses "cooking" for preparing; the set prepares and collects gases in a chemistry laboratory.
Who supplies Simple Appliances for Cooking Gas Lighter than Air?
Science Lab Supplies in Ambala, India supplies these sets to schools and colleges and prepares bulk quotations for distributors and tender contractors.
