Vacuum Pump Filter
Product Code : LSK-CL-10081
Vacuum Pump Filter (SKU LSK-CL-10081), also known as a water-jet filter pump or water aspirator, is an extruded brass device that fits on a laboratory water tap and creates a vacuum as the water flows through it. Chemistry laboratories connect it to a filter flask to speed up filtration without an electric pump. From Ambala, India, Science Lab Supplies offers it to schools, colleges, laboratories, tender contractors and distributors.
Specifications
The body is made of extruded brass. Water running through the pump drags air out of the side connection, so any vessel joined to it by tubing is drawn under vacuum for as long as the tap stays open. There are no motors or electrical parts; the suction depends on the water flow.

Applications and Experiments for the Vacuum Pump Filter
The filter pump is mainly used for suction filtration: a Buchner funnel sits on a side-arm flask, the pump pulls air from the flask, and the liquid is drawn quickly through the filter paper. It suits crystallisation and preparation practicals in Class 11–12, B.Sc. and B.Pharm. chemistry, and routine laboratory work.
- Class 12 and B.Sc. organic preparations: collecting and washing crystals after recrystallisation.
- Inorganic preparations: separating precipitates such as double salts from their mother liquor.
- Pharmacy practicals: filtering and drying solid products.
- Demonstrating reduced pressure, for example lowering the boiling point of warm water.
Fit a trap or safety bottle between the pump and the filter flask, and release the vacuum before closing the tap, so tap water cannot be sucked back into the filtrate.
Standard Scope of Supply
The Vacuum Pump Filter is supplied as a single unit as described above. The filter flask, Buchner funnel, filter paper and connecting rubber tubing are separate items that can be added to the quotation, so the whole suction filtration set arrives together.
Packing, MOQ and Lead Time
Quotations are prepared for one pump or for one per sink across several laboratories. Science Lab Supplies states the packing, delivery time and price for the number requested, and as a laboratory glassware supplier in India it can list the matching flasks and funnels alongside.
Science Lab Supplies is a registered exporter with an Importer-Exporter Code and can ship to buyers in Uganda, the UAE, Saudi Arabia, Oman, the Philippines and Nepal. Get in touch through the contact page, save the pump to the enquiry cart, or read the lab tender page for tender supply.
Frequently Asked Questions
How does a water filter pump create a vacuum?
Water flowing fast through the narrow brass jet carries air with it out of the side arm, lowering the pressure in whatever is connected there, such as a filter flask.
What is the Vacuum Pump Filter made of?
It is made of extruded brass, a metal that suits continuous contact with tap water in the laboratory.
Does it need electricity?
No. It works only from the water supply, so it is a simple option for labs without an electric vacuum pump. The vacuum achieved depends on your water flow.
Who supplies the Vacuum Pump Filter?
Science Lab Supplies supplies it from Ambala, India, to schools, colleges and distributors, and quotes single pumps as well as quantities for tenders.
