Microscale Vacuum Apparatus with Hand Pump
Product Code : SCL-CL-11878
Microscale Vacuum Apparatus with Hand Pump (SKU SCL-CL-11878) is a small bell jar, 10 cm high and 5 cm in diameter, evacuated with a hand pump so that each student group can explore low pressure at its own bench. Rather than watching a single teacher demonstration, learners run the experiments themselves. It suits middle-school science and Class 9–11 physics and chemistry. Science Lab Supplies supplies the apparatus from Ambala, India to schools, colleges, training institutes, distributors and tender contractors.
Specifications
The microscale bell jar measures 10 cm in height and 5 cm in diameter, small enough for a student workstation. Pumping air out by hand lowers the pressure inside, so objects and liquids placed in the jar react visibly within a few strokes, with no mains-powered vacuum pump needed.

Applications and Experiments for the Microscale Vacuum Apparatus
Reducing the pressure around an object shows students how much work the atmosphere normally does. With this apparatus a balloon swells, warm water boils without heating, and liquid can be moved between pipets. It supports air-pressure topics in NCERT Class 8 science and states of matter in Class 9 and 11.
- Class 8: air exerts pressure, shown by a small balloon expanding as the jar is pumped.
- Class 9 and 11: boiling point falls with pressure, shown with warm water.
- Volume change of foams, such as a marshmallow or shaving cream, as pressure drops.
- Transferring liquid from one pipet to another using pressure difference.
Use only warm, not hot, water, and let air back in slowly before lifting the jar.
Standard Scope of Supply
Each set comprises the microscale bell jar, 10 cm high and 5 cm in diameter, and the hand pump. Balloons, pipets, marshmallows and other test materials are not part of the set; any optional accessories you request are listed on the quotation.
Packing, MOQ and Lead Time
Because the apparatus is designed for student stations, many schools price one per group; a single set can be quoted too. The quotation covers packing, delivery time and price for your number, and other school chemistry lab equipment in India can be added.
Science Lab Supplies holds an Importer-Exporter Code and can ship to buyers in Egypt, Iraq, Nigeria, Kenya, Ghana and Ethiopia. Ask for a quotation through the enquiry cart, contact the team via the contact page, or read the lab tender page for tender procedure.
Frequently Asked Questions
How big is the bell jar?
It is 10 cm high and 5 cm in diameter, a microscale size meant for a student bench rather than a large demonstration jar.
What experiments can students do with it?
Expanding a balloon, boiling warm water at reduced pressure, watching a marshmallow or shaving cream grow, and moving liquid between pipets.
Who supplies the Microscale Vacuum Apparatus with Hand Pump?
Science Lab Supplies dispatches this set from Ambala, India. Schools, colleges, training institutes, distributors and tender contractors receive quotations directly.
Does it need electricity?
No. The vacuum is produced with the hand pump, which makes the apparatus practical for classrooms without bench power.
