Hand Vacuum Pump with Pressure Gauge
Product Code : LSK-CL-10082
Hand Vacuum Pump with Pressure Gauge (SKU LSK-CL-10082) is a hand-operated pump that removes air from small vessels and shows the vacuum reached on a built-in gauge. It moves 15 ml of air per stroke, can displace up to 725 ml, and has a valve to let air back in without disconnecting. Teachers use it for air-pressure demonstrations and small vacuum experiments. Science Lab Supplies supplies the pump from Ambala, India, to schools, colleges, tender contractors and distributors.
Specifications
Each stroke draws 15 ml of air, and the pump can displace up to 725 ml in total, which suits small flasks, syringes and demonstration hemispheres. The pressure gauge is marked in both centimetres and inches of mercury, and a release valve lets the vacuum go without removing the tubing.

Applications and Experiments for the Hand Vacuum Pump
The pump is used to show the effects of air pressure and reduced pressure with small, safe volumes, and the gauge turns each demonstration into a measurement. It supports air-pressure lessons in Class 8 and 9 science, fluid pressure in Class 11 physics, and small-scale vacuum work in chemistry.
- Class 8 science: showing that air exerts pressure, for example with Magdeburg hemispheres.
- Class 11 physics: reading and converting pressure in cmHg and inHg.
- Chemistry: lowering the boiling point of warm water by reducing pressure in a sealed flask.
- Microscale vacuum filtration or degassing of small samples.
Standard Scope of Supply
The Hand Vacuum Pump is supplied with its pressure gauge fitted and the release valve built in, as described above. Vessels, hemispheres or extra tubing used in the demonstrations are separate items and can be added to the same quotation if needed.
Packing, MOQ and Lead Time
We quote for a single pump for demonstrations or several for group practicals. Each Science Lab Supplies quotation lists packing, delivery time and price for that quantity, and chemistry lab equipment in India such as Magdeburg hemispheres or a manometer can go on the same quotation.
With its Importer-Exporter Code, Science Lab Supplies is a registered exporter able to ship to buyers in the UAE, Saudi Arabia, Oman, the Philippines, Nepal and Bangladesh. Use the contact page to ask for a quote, keep a list in the enquiry cart, or see the lab tender page for tender buying.
Frequently Asked Questions
How much air does the pump move?
It draws 15 ml of air per stroke and can displace up to 725 ml, enough for small flasks, syringes and demonstration hemispheres.
What units does the pressure gauge show?
The gauge reads in both centimetres and inches of mercury, so students can compare the two scales and convert between them.
Can the vacuum be released without taking the pump off?
Yes. A built-in valve lets air back in without disconnecting the pump, so an experiment can be repeated straight away.
Who supplies the Hand Vacuum Pump with Pressure Gauge?
Science Lab Supplies supplies it from Ambala, India, to schools, colleges and distributors, quoting for single pumps and class or tender quantities.

A hand pump is the starting point for several pressure experiments. These four items extend it: a microscale vacuum set, Magdeburg hemispheres for the classic air-pressure demonstration, a general-purpose vacuum pump rated at about 50 litres per minute and a U-tube manometer for comparing pressure readings.
