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. Science Lab Supplies supplies the set from Ambala, India for chemistry practicals in schools, colleges and training institutes, and for distributors and tender contractors.
Specifications
The set combines a conical flask with a side arm, porcelain Buchner funnels, a water pump that creates the vacuum, and a three-neck Woulfe bottle placed between flask and pump as a trap. Rubber tubes, plastic tubes and rubber stoppers connect and seal the parts.

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 standard 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 and washing recrystallised products.
- B.Sc. inorganic and analytical work: separating precipitates from mother liquor.
- Pharmacy and diploma labs: routine suction filtration.
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 eye protection.
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 part of the listing.
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, we can also quote spare flasks, funnels and tubing on the same sheet.

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 pulls liquid through 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.
Who supplies the Equipment for Vacuum Filtration?
The set is supplied by Science Lab Supplies from Ambala, India to schools and colleges, with quantity quotations for distributors and tender contractors.
Is filter paper included?
No. Filter paper is a consumable and is not in the listing. Cut or buy circles to fit your Buchner funnel.
