Simple Devices for Studying the Properties of Substances
Product Code : SCL-CL-11458
Simple Devices for Studying the Properties of Substances (SKU SCL-CL-11458) is a basic test-tube set: an 18 x 150 mm test tube closed with a holed rubber stopper, through which an L-shaped 6 mm glass tube leads any gas or vapour away. Students heat or react small samples and pass the product into a second tube for testing. Science Lab Supplies supplies it from Ambala, India to schools and colleges for everyday chemistry practicals, and quotes distributors and tender contractors.
Specifications
The device has three parts: a glass test tube 18 mm in diameter and 150 mm long, a rubber stopper with one hole, and a glass tube of 6 mm outer diameter bent into an L shape that fits through the stopper and directs gas sideways out of the tube.

Applications and Experiments for the Properties of Substances Set
This set is used for small-scale tests where a substance is heated or reacted and the gas given off is examined, for example passing carbon dioxide into limewater. The L-shaped outlet makes it easy to dip the tube end into a reagent in a second test tube.
- NCERT Class 7 science: physical and chemical changes, including the limewater test for carbon dioxide.
- NCERT Class 10 science: thermal decomposition and the reaction of carbonates with acids.
- Class 11 chemistry: tests for gases in salt analysis.
Loosen the stopper or remove the delivery tube from the reagent before heating stops, so liquid is not drawn back into the hot tube. Use a holder and eye protection when heating.
Standard Scope of Supply
You receive one 18 x 150 mm test tube, one rubber stopper with a hole, and one L-shaped glass tube of 6 mm outer diameter. A test-tube holder, burner and reagents are not included in the listing.
Packing, MOQ and Lead Time
Because the set is small, schools usually order it in class quantities. Tell us how many you need and the quotation will show the packing, delivery time and price, with holders, burners or spare stoppers listed alongside if you ask.
Using its Importer-Exporter Code as a registered exporter, Science Lab Supplies can ship to buyers in Malaysia, Peru, Egypt, Iraq, Nigeria and Kenya. Write to us through the contact page, add the set to the enquiry cart, or see the lab tender page.
Frequently Asked Questions
What is the L-shaped tube used for?
It carries gas from the stoppered test tube sideways and down, so the end can be dipped into limewater or another test reagent held in a second tube.
Can the test tube be heated?
Small samples are commonly heated in this kind of test tube over a spirit lamp or burner. Heat gently, point the mouth away from people and use a holder.
Who supplies Simple Devices for Studying the Properties of Substances?
Science Lab Supplies supplies these sets from Ambala, India to schools and colleges, and quotes distributors and tender contractors for bulk quantities.
Is this suitable for school chemistry lab equipment in India?
Yes. It is a simple glassware set for small-scale tests at school level and can be quoted with other Chemistry Lab items.
