Equipment for Vacuum Filtration
Product Code : SCL-CL-11457
Equipment for Vacuum Filtration (SKU SCL-CL-11457) is a suction filtration set in which a water-jet pump draws air out of a side-arm conical flask, pulling liquid quickly through filter paper in a porcelain Buchner funnel. It separates crystals and precipitates much faster than gravity filtration. Chemistry practical labs in schools, colleges and training institutes, along with distributors and tender contractors, obtain the set from Science Lab Supplies, which dispatches it from Ambala, India.
Specifications
This suction filtration set is broken down part by part in the table. In short, it combines a conical flask with a side arm, porcelain Buchner funnels, a water pump that creates the vacuum and a three-neck Woulfe bottle used as a trap, with rubber tubes, plastic tubes and rubber stoppers to connect and seal everything.

Applications and Experiments for the Vacuum Filtration Equipment
The equipment is used to collect and wash solid products quickly and to leave them fairly dry, which matters when crystals are weighed or tested for melting point. It is a standard technique in preparation experiments from senior school to undergraduate level.
- Class 12 chemistry practicals: collecting crystals of prepared inorganic double salts and organic compounds.
- B.Sc. organic chemistry: filtering recrystallised products and washing them with cold solvent from a 500 ml Plastic Washing Bottle (Pisetta).
- B.Sc. inorganic and analytical work: separating precipitates from mother liquor.
- Pharmacy and diploma labs: suction filtration practice.
Glassware under vacuum can implode if it is cracked or chipped. Inspect the flask before each use, never apply vacuum to thin-walled vessels, and wear Protective Glass eyewear.
Standard Scope of Supply
Supplied parts are a conical flask with side arm, porcelain Buchner funnels, a water pump for vacuum, a three-neck Woulfe bottle, and rubber tubes, plastic tubes and rubber stoppers. Filter paper and a tap connection for the water pump are not included; extra Rubber Stoppers of Various Diameters with Holes can be quoted.
Packing, MOQ and Lead Time
Ask for a quotation for one set or for enough sets to equip a practical class. It will show the packing, delivery time and price for that quantity. As a laboratory glassware supplier in India, Science Lab Supplies can also quote spare flasks, funnels and tubing on the same sheet.
Science Lab Supplies is a registered exporter with an Importer-Exporter Code, able to ship to buyers in Vietnam, Malaysia, Peru, Egypt, Iraq and Nigeria. Let us know how many filtration stations you are fitting out via the contact page or the enquiry cart; where a tender governs the purchase, the lab tender page sets out the steps.
Frequently Asked Questions
How does the water pump create a vacuum?
Water running through the pump from a tap drags air with it, lowering the pressure in the connected flask. The pressure difference then pulls liquid through the filter paper in the Buchner funnel.
What is the Woulfe bottle for?
It acts as a trap between the flask and the pump, so that water cannot suck back into the filtrate if the tap pressure changes during filtration.
Who supplies the Equipment for Vacuum Filtration?
You can buy the set from Science Lab Supplies, which sources and ships it from Ambala, India. Single sets go directly to schools and colleges; distributors and tender contractors get quantity quotations.
Is filter paper included?
No. Filter paper is a consumable and is not included with the set. Cut or buy circles to fit your Buchner funnel, and add them to the same quotation if you wish.
