Product Code : SCL-F-10364
Quick answer: This is a vacuum filtration assembly combining a filter funnel, a receiving flask, and a rubber stopper connection between them, used where vacuum-assisted filtration is needed to separate solids from liquids faster than gravity filtration alone.

Why Use Vacuum Filtration Over Gravity
Vacuum filtration pulls liquid through the filter medium rather than relying on gravity alone, cutting filtration time significantly for slow-draining precipitates, fine powders or larger sample volumes. In this kit, the rubber stopper seals the join between the filter funnel and the receiving (vacuum) flask, which connects in turn to a vacuum source or aspirator. For a Buchner-style funnel with a fused sintered disc instead of loose filter paper, see the Buchner Funnel with Sintered Disc elsewhere in this range. Buyers should confirm exact kit capacity, flask size and stopper bore at enquiry stage to match existing vacuum apparatus.
Frequently Asked Questions
What does this kit include?
A filter funnel, a receiving (vacuum) flask, and a rubber stopper that connects the two, forming a complete vacuum filtration assembly.
Why choose vacuum filtration over gravity filtration?
Vacuum filtration pulls liquid through the filter medium rather than relying on gravity alone, filtering slow-draining precipitates, fine powders or larger volumes considerably faster.
What else do I need to run this kit?
A vacuum source or aspirator connected to the receiving flask's side arm, and filter paper or a sintered disc funnel depending on the filtration job.
