Gas Jar Manufacturer,Supplier and Exporter in India

Gas Jar (Product Code: SCL-686/089) is a tall, open-mouthed cylinder of clear soda glass, 200 x 50 mm, used to collect and hold a gas so that its properties can be tested in front of a class. Students fill it with oxygen, hydrogen or carbon dioxide prepared at the bench, then cover it and carry out tests such as a glowing splint or lime water. The glass is chemical resistant and heat resistant, and its clarity lets everyone watch a colour change or a flame inside. It is a core part of any gas collection apparatus in a school laboratory and is made by Jain Scientific Equipments Pvt Ltd (ScienceLab), Ambala, India.

Specifications

Typical Use

For gases that do not dissolve readily in water, fill the jar with water, invert it over a beehive shelf in a pneumatic trough and let the gas from the delivery tube push the water out. Gases that are heavier or lighter than air can instead be collected by upward or downward displacement of air, with the jar standing upright or mouth down. Once full, slide a greased cover over the mouth, lift the jar out and keep it covered until the test.

Typical tests include relighting a glowing splint in oxygen, burning sulphur or magnesium ribbon held in a deflagrating spoon, or shaking carbon dioxide with lime water. When burning anything inside the jar, pour a little sand or water into the bottom first so hot residues cannot crack the base. Although the glass is heat resistant, a gas jar is a collection vessel rather than a heating vessel, so keep it off the burner. These simple habits make it one of the most reliable pieces of chemistry lab equipment in India's school practical rooms.

Collecting a gas in the jar calls for a few more pieces of apparatus:

• Gas Jar Cover — closes the mouth once the jar is full.
• Pneumatic Trough — the water bath for collecting gas over water.
• Beehive Shelf, Porcelain — supports the inverted jar over the gas outlet.
• Delivery Tube — carries gas from the generating flask to the jar.
• Deflagrating Spoon — lowers burning samples into the collected gas.

Frequently Asked Questions

What size is the gas jar?
It measures 200 x 50 mm and is made of clear soda glass.

Is a cover included?
This listing is for the gas jar. A gas jar cover is available as a separate item and can be quoted with it; ask through the contact page if you want them paired.

Can the jar be heated?
The glass is heat resistant and copes with combustion tests inside it, but it should not be placed over a burner. Protect the base with sand or water when burning samples.

Why soda glass rather than borosilicate?
Gas jars are used for collecting and holding gases rather than direct heating, so soda glass suits the job. Choose borosilicate vessels for anything that goes over a flame.

Which gases can it be used for?
Any gas prepared in school practicals, such as oxygen, hydrogen or carbon dioxide. The collection method depends on how soluble and how dense the gas is.

Do you supply class sets or export orders?
Yes. ScienceLab supplies institutions and dealers in India and international markets; quantities and delivery are confirmed on enquiry.
