Crushing Can Manufacturer,Supplier and Exporter in India

Crushing Can (Product Code: SLE/PHY/150) is a light-walled tin plate can with an air-tight screw cap used to demonstrate the force exerted by atmospheric pressure in school and college physics laboratories. Teachers rely on it for a memorable class demonstration in which the 75 mm diameter can collapses once the air inside has been driven out by steam. It is made by Jain Scientific Equipments Pvt Ltd (ScienceLab), an OEM manufacturer, at its own factory in Ambala, India, as part of its physics lab equipment for schools.

Specifications

What Is the Crushing Can Used For?

The crushing can experiment shows students that the air around them presses on every surface with a surprisingly large force. A little water is heated in the open can until steam pushes most of the air out, the heat is removed and the cap is screwed on tight. As the steam cools and condenses, the pressure inside falls far below the pressure outside, and the atmosphere crumples the thin walls, often with an audible crack. Pouring cold water over the sealed can makes the collapse faster and more dramatic.

For safety, never heat the can with the cap in place, and handle the hot can with tongs or heat-resistant gloves. Only a shallow layer of water is needed, which keeps heating time short. The demonstration fits naturally into lessons on air pressure, gas laws and weather, and it is a practical addition to any physics lab equipment list for schools in India and abroad.

What to Specify When Ordering

• Number of cans — the light-walled can is designed to deform, so plan one per demonstration or group.
• Confirmation that the 260 x 75 mm size suits your burner and tripod set-up.
• Any heating accessories you also need, such as a burner, tripod or gauze.
• Delivery location, within India or overseas, so the quotation can include dispatch details.

OEM Manufacturer

Jain Scientific Equipments Private Limited trades as ScienceLab and is the OEM (original equipment manufacturer) of the Crushing Can. The can is produced at the company's own licensed factory at Saha, Ambala, Haryana, India, so schools, colleges, laboratory dealers and importers deal directly with the maker instead of a trading intermediary. Replacement cans for future terms can be ordered from the same source — ask us about current availability. You can read more about the company on our company profile.

Frequently Asked Questions

What size is the Crushing Can?
The Crushing Can measures 260 x 75 mm, with a 75 mm diameter body made from light-walled tin plate and closed by an air-tight screw cap. The thin walls are what allow atmospheric pressure to crush it visibly during a class demonstration.

How does the Crushing Can show atmospheric pressure?
The Crushing Can shows atmospheric pressure by replacing the air inside with steam. Once the cap is sealed and the steam condenses, the pressure inside drops sharply, so the unbalanced pressure of the outside air pushes the thin tin plate walls inward until the can collapses.

Can the Crushing Can be heated with the cap closed?
No. The Crushing Can must always be heated with the screw cap removed so that steam can escape freely. Fit the air-tight cap only after the heat source has been taken away, then let the can cool or pour cold water over it.

Can one Crushing Can be used for several demonstrations?
A Crushing Can is light-walled and meant to deform, so a collapsed can generally cannot be returned to its original shape. Most teachers treat it as a demonstration consumable and order enough cans for the number of classes or groups they plan to teach.

Who manufactures the Crushing Can?
The Crushing Can is manufactured by Jain Scientific Equipments Pvt Ltd (ScienceLab), the OEM, at its own factory at Saha, Ambala, Haryana, India. Buyers receive quotations and repeat supplies directly from the manufacturer rather than through a trader.
