Pneumatic Trough, Glass Manufacturer,Supplier and Exporter in India

Pneumatic Trough, Glass (Product Code: SLE/CL/89) is a wide, shallow water vessel for collecting gases over water, made from clear pressed soda-lime glass with a 25 cm diameter, a height of 12.5 cm and a capacity of 5000 ml. The transparent walls let students watch bubbles displace water from an inverted gas jar, which makes the classic gas-preparation experiments easy to follow. It is heat and chemical resistant and forms the centre of the gas collection apparatus used in school and college chemistry labs. It is manufactured by Jain Scientific Equipments Pvt Ltd (ScienceLab), Ambala.

Specifications

Typical Use

The trough is filled with water and a gas jar, also full of water, is inverted into it and rested on a beehive shelf. A delivery tube from the gas generator is led under the shelf, and the gas bubbles up into the jar, pushing the water out. This downward displacement of water is how oxygen, hydrogen and other gases that are only slightly soluble in water are prepared and collected in practical classes, and it is a standard part of school chemistry lab equipment in India. Biology teachers also use the trough to hold water plants under an inverted funnel when demonstrating the oxygen given off in photosynthesis.

Set the trough on a flat, stable bench before filling it, as a full vessel is heavy. When heating a generator flask, always withdraw the delivery tube from the water before removing the flame to prevent water being sucked back into the hot flask. After the experiment, empty and rinse the trough with water, and dry it before storage; handle it with both hands and avoid knocks against hard surfaces.

Frequently Asked Questions

What size is the trough?
It measures 25 cm in diameter and 12.5 cm in height, with a capacity of 5000 ml, which leaves room for a beehive shelf and gas jar.

Is a beehive shelf or gas jar included?
The listing covers the trough only. Order the shelf, gas jars, covers and delivery tube separately, or ask us to quote the complete set.

Can the trough be heated?
It is listed as heat resistant, so warm water is fine, but a pneumatic trough is not designed for direct flame heating. Avoid sudden temperature changes, as with any soda-lime glassware.

Why choose glass over a plastic trough?
Glass stays clear for longer, resists staining from chemicals and gives a better view of gas collection. A plastic trough is lighter and less fragile for younger students.

How should it be cleaned?
Rinse with water after each use and wash with a mild detergent if deposits form; the glass is chemical resistant, but avoid abrasive pads that scratch the surface.

Do you supply schools in quantity or overseas?
Yes. We handle institutional, tender and export orders for India and international markets; mention product code SLE/CL/89 and the quantity in your enquiry via the contact page.
