Pneumatic Trough, Plastic
Industrial-Grade Polypropylene Construction: Fabricated from high-impact, chemically inert plastic that resists cracking and thermal stress, ensuring long-term structural integrity and zero leakage during prolonged immersion.
Integrated Support Architecture: Features a reinforced internal floor designed to securely accommodate beehive shelves and gas jars, facilitating stable gas delivery without accidental container shifting during sensitive volumetric displacement.

Quick answer: A Pneumatic Trough is a wide, water-filled basin used to collect gas by water displacement during chemistry experiments, letting students see and measure the volume of gas produced by a reaction. Pneumatic Trough, Plastic is priced at approximately ₹300 (indicative market benchmark, incl. GST, August 2026).
The Pneumatic Trough supports the classic gas-collection-by-water-displacement technique: a container (such as an inverted test tube or gas jar) is filled with water and positioned upside down in the trough, and as a reaction generates gas, the gas bubbles up and displaces the water inside the container, effectively collecting and allowing visual measurement of the gas produced. This method works well for gases that don’t dissolve significantly in water, making it a standard technique taught in secondary and college chemistry practicals covering gas laws, reaction stoichiometry, or simply demonstrating that a reaction produces a measurable gas. Made from heavy-duty, impact-resistant plastic, this trough offers a durable, leak-proof basin suited to repeated classroom use.

Frequently Asked Questions
How does water-displacement gas collection work?
A gas-generating reaction produces bubbles that rise and displace water inside an inverted, water-filled container positioned in the trough, allowing the gas to be collected and its volume observed.
What gases can be collected this way?
This method works best for gases with low solubility in water; highly water-soluble gases (such as ammonia) are generally not well suited to water displacement — confirm the appropriate collection method for your specific experiment.
What experiments typically use a pneumatic trough?
It is commonly used in experiments demonstrating gas-producing reactions, gas-law verification, and reaction-stoichiometry practicals in secondary and college chemistry coursework.
Does STEMAids supply this in bulk for institutional labs?
Yes — STEMAids supplies laboratory equipment including pneumatic troughs for institutional and bulk orders; contact STEMAids to confirm current quantities and pricing.
Are exact trough dimensions and capacity available for tender specification?
Exact dimensions and capacity have not been independently verified for this listing. Institutions preparing tender documents should confirm precise specifications directly with STEMAids before finalising procurement paperwork.
Is STEMAids a registered manufacturer of this product?
Yes. Eduscope Smart Learning Solutions Private Limited is a Udyam-registered micro manufacturing enterprise (UDYAM-DL-06-0069460) and is ISO 9001:2015 certified. See the About page for full registration and certification details — manufacturer-stated, verify before citing in procurement documents.
