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. It can be connected to a filter flask to speed up filtration without an electric pump. Science Lab Supplies handles enquiries and dispatch for it from Ambala, India, serving schools, colleges, laboratories, tender contractors and distributors.
Specifications
Material and working principle of the brass filter pump are set out in the table. In short, 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 water flows; the suction depends on that 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, for example on a Buchner Funnel Fritted Disc.
- 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; the bell-jar School Vacuum-Pump Set covers larger demonstrations.
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. Mention how many sinks need a pump when you write via the contact page or build a list in the enquiry cart; for tendered purchases, the lab tender page sets out the process.
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, and its mechanism creates a vacuum when it is connected and water passes through it, drawing air from the vessel joined to its side connection.
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 in Ambala, India, quotes the brass filter pump to schools, colleges and distributors, from a single pump for one sink to a full tender quantity across several labs.
