Product Code : EL-SLE-5649
Jlab Export is a leading Pneumatic Trough Manufacturer,and suppliers in India
Pneumatic Trough (code EL-SLE-5649) is a circular polypropylene trough, 250 mm in diameter and 100 mm high, used to collect gases over water in school and college chemistry labs. Being plastic, it will not shatter like a glass trough, and the polypropylene is autoclavable, so the trough can also serve for storage, sterilizing and drying labware. It is made by Jain Laboratory Instruments Pvt Ltd (JLab) at its works in Ambala, India.

Choose this trough when you want individual 250 mm circular troughs for gas collection practicals. The size-range listing suits buyers ordering several diameters in packs, the rectangular trough comes with its own gas-collection insert, and the smaller 180 x 60 mm trough suits storage or shallow work.
What Is a Pneumatic Trough Used For?
Collecting a gas over water is a standard chemistry practical for gases that do not dissolve readily in water, such as oxygen and hydrogen. The trough is filled with water, a gas jar is filled to the brim, covered, inverted and stood mouth-down on a beehive shelf under the water, and the delivery tube from the reaction flask is led under the shelf. Bubbles of gas rise into the jar and push the water out, so the amount collected can be seen, and the jar can be covered and lifted out for testing. Very soluble gases such as ammonia or hydrogen chloride are collected by other methods.
When the gas is made by heating, take the delivery tube out of the water before removing the flame, so that cold water is not sucked back into the hot apparatus. After use, empty and rinse the trough and let it dry; the autoclavable polypropylene also allows it to be used for sterilizing or drying small labware. This makes it a practical part of any gas collection apparatus set in school chemistry.
What to Specify When Ordering
- Size — this listing is the 250 x 100 mm circular trough; ask if you need other diameters or heights.
- Quantity — the minimum order is 10 units; plan one per gas-preparation set-up.
- Gas collection accessories — add beehive shelves, gas jars with lids and delivery tubes to the same enquiry.
Frequently Asked Questions
What is the size of this pneumatic trough?
It is circular, 250 mm in diameter and 100 mm high, made of polypropylene.
Which gases can be collected over water with it?
Gases that are only slightly soluble in water, such as oxygen and hydrogen, are commonly collected this way. Very soluble gases, for example ammonia, need a different collection method.
Can the trough be autoclaved?
Yes. The polypropylene is listed as autoclavable, so the trough can also be used for storage, sterilizing and drying labware.
Are a beehive shelf and gas jar included?
No. This listing covers the trough only. Beehive shelves, gas jars with lids and glass delivery tubes are separate items, linked below, and can be quoted in the same enquiry.
How does it differ from the rectangular plastic trough?
This trough is circular, 250 x 100 mm and autoclavable. The Pneumatic Trough Plastic JLab is a rectangular trough supplied with a removable plastic insert with two holes for gas collection.
What information is needed for an export quotation?
Send the quantity, any other sizes required, the destination country and port or city, your preferred delivery terms such as FOB or CIF, packing or labelling requirements, and the tender reference if applicable.
Who manufactures this trough?
Jain Laboratory Instruments Pvt Ltd, trading as JLab, makes it at its works in Ambala, Haryana, India, and quotes for it directly.
OEM Manufacturer
JLab is the trading name of Jain Laboratory Instruments Pvt Ltd, an Indian manufacturer of chemistry apparatus, plasticware and school science equipment, incorporated in 2017 and based on Hargolal Road, Ambala, Haryana. The pneumatic trough is produced at JLab’s own works rather than traded in, so schools, colleges, dealers and importers buy factory-direct, every trough is visually inspected before it is packed, and repeat orders come from the manufacturer itself. JLab exports worldwide and ships to buyers in every region — for example Peru in South America, Slovakia in Eastern Europe, Kyrgyzstan in Central Asia, Thailand in Southeast Asia and Eswatini in Southern Africa. Details for tender buyers are on the JLab lab tenders page.
Gas Collection Accessories
- Beehive Shelf — a glazed stoneware shelf that supports the inverted gas jar in the trough.
- Beehive Shelves (Porcelain) — glazed ceramic beehive shelves for collecting gases over water.
- Gas Jar with Lid, Glass — a glass jar with lid for collecting and testing the gas.
- Delivery Tube Glass — straight and bent soda lime glass tubes that carry the gas from the flask.
