Gas Jar with Lid, Glass (code EL-SLE-4562) is a glass gas jar supplied with a lid, designed to collect the gases produced in experiments in school and college chemistry labs. It measures 8 x 2 inches (about 203 x 51 mm), a convenient size for collecting a jar of gas over water and testing it at the bench. It is made by Jain Laboratory Instruments Pvt Ltd (JLab) at its works in Ambala, India, for educational institutions and other laboratories.

Specifications

How Does It Compare with Other JLab Gas Jars?

All three are close in size. Choose this jar when you want a gas jar and lid ordered together; pick the borosilicate Gas Jar with Cover where a heat-resistant jar with a ground-in cover plate is specified, or the soda-glass Gas Jar as a plain jar for routine collection.

What Is the Gas Jar Used For?

Gas jars hold the gases students prepare in school chemistry practicals on oxygen, hydrogen and carbon dioxide, typically in class 9 and class 10. To collect a gas over water, fill the jar with water, cover it, turn it upside down in a pneumatic trough and stand it on a beehive shelf; gas from the delivery tube bubbles up and pushes the water out. When the jar is full, slide the lid across the mouth under the water and lift it out. Gases denser than air, such as carbon dioxide, can also be collected by upward displacement of air with the jar upright. The covered jar then goes to the tests — a glowing splint relights in oxygen, a lighted splint gives a squeaky pop with hydrogen, and carbon dioxide puts out a flame and turns limewater milky.

Gas jars are also used for burning substances in oxygen on a deflagrating spoon (put a little sand or water in the bottom first, so hot fragments do not crack the glass) and, placed mouth to mouth, for showing how gases diffuse. As the glass type is not specified, do not heat the jar directly or expose it to sudden temperature changes; wash and dry it after use and store it with its lid.

What to Specify When Ordering

• Quantity — the minimum order is 10 gas jars; a class set usually allows two or three jars per group.
• Glass and lid details — ask JLab to confirm the glass type and the lid material in the quotation if your tender names them.
• Collection set — add a pneumatic trough, beehive shelves and deflagrating spoons to the same enquiry for a complete gas-collection bench.

Frequently Asked Questions

What size is this gas jar?
It is listed as 8 x 2 inches, about 203 x 51 mm. For gas jars the larger figure is normally the height and the smaller the diameter; JLab can confirm this when quoting.

What is the gas jar used for?
Collecting gases produced in experiments, usually over water in a pneumatic trough, and holding them covered until they are tested or used in combustion experiments.

Is it borosilicate glass, and what is the lid made of?
The listing says glass with a lid but does not name the glass type or the lid material. Ask JLab to state both in your quotation; the separate Gas Jar with Cover listing is the one described in borosilicate glass with a ground-in cover plate.

How do I collect a gas over water with it?
Fill the jar with water, invert it in a trough of water over a beehive shelf, and let the gas bubble in from the delivery tube until all the water is pushed out. Then cover the mouth with the lid while it is still under water and lift the jar out.

Can I burn substances inside it?
Yes, that is a common use with a deflagrating spoon, but place a thin layer of sand or water in the bottom first to protect the glass, and let the jar cool before washing it.

What should an export enquiry include?
The quantity, destination country and port or city, delivery terms such as FOB or CIF, any packing or labelling requirements for glassware, and the tender reference if relevant.

Who manufactures this gas jar?
JLab — Jain Laboratory Instruments Pvt Ltd — at its works in Ambala, Haryana, India.

OEM Manufacturer

JLab is the trading name of Jain Laboratory Instruments Pvt Ltd, an Indian manufacturer of chemistry lab glassware and school science equipment, incorporated in 2017 and based on Hargolal Road, Ambala, Haryana. The gas jar is produced at JLab’s own works rather than bought from a trader, so schools, colleges, dealers and importers buy it factory-direct, every jar is visually inspected before it is packed, and repeat orders come from the same manufacturer. JLab exports worldwide and serves buyers in every region — North Macedonia in Southern Europe, Ukraine in Eastern Europe, Hong Kong in East Asia, Senegal in West Africa and Lithuania in Northern Europe among them. Tender information is on the JLab lab tenders page.

Gas Collection Accessories

• Pneumatic Trough — a circular polypropylene trough for collecting gas over water.
• Beehive Shelf — a glazed stoneware shelf that supports the inverted jar in the trough.
• Deflagrating Spoon With Lid — a steel spoon on a rod for burning substances inside a gas jar.
• Gas Jar with Cover — a borosilicate gas jar with a ground-in cover plate.
