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 its pressure 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. It serves air-pressure demonstrations and small vacuum experiments. Buyers can obtain it through Science Lab Supplies, whose Ambala, India office quotes schools, colleges, tender contractors and distributors.
Specifications
Stroke volume, displacement, gauge scales and the release valve of the hand pump each have a row below. In short, each stroke draws 15 ml of air and the pump displaces up to 725 ml in total; the gauge is marked in centimetres and inches of mercury, and the 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 of small samples through a 120 ml porcelain Vacuum Filtration Funnel (Buhner Funnel); for larger runs, the tap-driven Vacuum Pump Filter is an alternative.
Standard Scope of Supply
The Hand Vacuum Pump is supplied with its pressure gauge and the vacuum release valve, 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, so one order covers the whole experiment.
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. Say whether you need one demonstration pump or a set for group work in a message through the contact page, or queue it in the enquiry cart; formal tenders run through the lab tender page.
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 in total, so the number of strokes needed for a given vessel can be worked out in class.
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. The pump is fitted with a valve that releases the vacuum without disconnecting it, so air can be let back into the vessel and the experiment repeated straight away while the gauge still reads in cmHg and inHg.
Who supplies the Hand Vacuum Pump with Pressure Gauge?
It comes from Science Lab Supplies, based in Ambala, India, which prices it for schools, colleges and distributors in any quantity from one pump to a class or tender lot.
