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 sells the set out of Ambala, India, to school and college laboratories and quotes resellers and tender contractors in bulk.
Specifications
The straight-tube set's measurements are listed as separate rows in the table. In short, a test tube 18 mm in diameter and 150 mm long is the reaction vessel, and a rubber stopper with a single hole holds a straight glass tube of 6 mm external diameter, over which an inverted tube can be lowered.

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 pop test for hydrogen, using a lighted Wood Splints splint.
- Class 11 chemistry: preparation of hydrogen and choice of collection method, with the gas gathered in an inverted 18 x 180 mm Test Piece tube.
- 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 wearing Protective Glass eyewear.
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 included, and any of them can be added to the quotation for your laboratory.
Packing, MOQ and Lead Time
Order a handful for demonstrations or a set for every student group. Name the number of sets and the quotation will list packing, delivery time and price. If you are putting together chemistry lab equipment in India for a new lab, the other gas sets can be quoted with it.
As an Importer-Exporter Code holder and registered exporter, Science Lab Supplies can ship to buyers in Nigeria, Kenya, Ghana, Ethiopia, Tanzania and Uganda. Share the number of student groups through the contact page, or line the sets up in the enquiry cart, to receive a price; formal tenders are handled as described on the lab tender page.
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 of the open mouth.
Is "cooking" a translation of preparing?
Yes. The product name uses "cooking" for preparing; the set prepares and collects gases in a chemistry laboratory and has nothing to do with food or kitchen use.
Who supplies Simple Appliances for Cooking Gas Lighter than Air?
The sets are supplied by Science Lab Supplies of Ambala, India. Schools and colleges buy them directly, and distributors and tender contractors can ask for bulk pricing on a formal quotation.
