School Vacuum-Pump Set
Product Code : SCL-PL-12377
School Vacuum-Pump Set (SKU SCL-PL-12377) is an educational vacuum chamber and pump set for showing what happens to air, water and pressure when air is pumped out of a closed chamber. Teachers use it for air-pressure and boiling-point demonstrations in school physics and chemistry lessons. Science Lab Supplies, a physics instruments supplier in India, sends the set from Ambala to schools, colleges, training institutes, tender contractors and distributors.
Specifications
The set pairs a pump with a vacuum bell-jar chamber that tapers from 4.75 × 4.75 in (about 121 × 121 mm) at the top to 3.75 × 3.75 in (about 95 × 95 mm) at the bottom. The items for each demonstration are placed inside the chamber before the air is pumped out.

Applications and Experiments for the School Vacuum-Pump Set
A classic demonstration is hot water that has stopped boiling starting to boil again once air is pumped out, showing that boiling point falls with pressure. The same chamber supports a vacuum fountain, cooling by evaporation until ice forms, vacuum coating and a range of atmospheric pressure experiments.
- Class 8–9 science: air exerts pressure, and atmospheric pressure experiments.
- Class 11 physics: effect of pressure on boiling point, and evaporation causing cooling.
- Chemistry lessons: evaporation and change of state at reduced pressure.
- Teacher demonstrations of a vacuum fountain and vacuum coating.
An evacuated chamber is under heavy outside pressure: run demonstrations under teacher supervision, keep students at a safe distance and let air back in slowly.
Standard Scope of Supply
The School Vacuum-Pump Set is supplied as described above: the vacuum pump and the bell-jar vacuum chamber of the stated dimensions. Beakers, water and any items placed inside for particular demonstrations are separate, and optional accessories can be listed on the quotation.
Packing, MOQ and Lead Time
A quotation can be raised for a single set, for one set in each of several labs, or for a whole district tender. It shows the packing, delivery time and price for the quantity involved, and bell jars or other air-pressure apparatus can go on it too.
As a registered exporter with an Importer-Exporter Code, Science Lab Supplies can ship to buyers in Rwanda, South Africa, Qatar, Sri Lanka, Vietnam and Malaysia. Contact the team via the contact page, send a list through the enquiry cart, or see the lab tender page.
Frequently Asked Questions
Which demonstrations can be done with this set?
It supports boiling water under reduced pressure, a vacuum fountain, evaporation icing, vacuum coating and atmospheric pressure experiments, covering air-pressure and change-of-state topics in physics and chemistry lessons.
How big is the vacuum chamber?
The chamber measures 4.75 × 4.75 in (about 121 mm square) at the top and 3.75 × 3.75 in (about 95 mm square) at the bottom, which suits small beakers and demonstration items.
Who supplies the School Vacuum-Pump Set?
Science Lab Supplies supplies this set from Ambala, India, to schools, colleges and tender buyers, and can list it on one quotation together with other air-pressure and heat apparatus.
Related Air-Pressure Apparatus
Vacuum demonstrations fit naturally into a sequence of air-pressure activities. These four items add extra chambers, a hand-operated pump, a dramatic crushing demonstration and a sound-in-vacuum device, so a school can cover the whole topic, and all can be quoted with the set.
- Bell Jars — additional chambers for vacuum work.
- Hand Vacuum Pump — a manual pump for small-volume demonstrations.
- Crushing Can — shows the force of atmospheric pressure.
- Demonstration Device of an Alarm from a Clock Under a Bell — sound fading as air is removed.
