Buchner Funnel with Sintered Disc
Product Code : LSK-LF-10397
Buchner Funnel with Sintered Disc (SKU LSK-LF-10397) is a filter funnel with a porous sintered disc in place of filter paper, used with suction to collect and wash precipitates and crystals. It suits B.Sc. and M.Sc. chemistry practicals, pharmacy labs and research or quality-control work. A full porosity set or a single size can be priced by Science Lab Supplies, Ambala, India, for universities, schools, laboratories, tender contractors and resellers.
Specifications
The table records every specification of this sintered-disc Buchner funnel. In short, it has a fire-polished rim and stem, comes in six disc porosity grades from 0 to 5, and is made in five capacities from 35 ml to 1000 ml, so one design serves small recrystallisations and larger suction filtrations.

Applications and Experiments for the Sintered Buchner Funnel
Fitted to a filter flask under vacuum, the sintered funnel pulls liquid quickly through the disc and leaves the solid on top, where it can be washed and dried. Because no paper is used, fibres cannot contaminate the product and the disc suits reagents that attack filter paper.
- B.Sc. organic chemistry: collecting recrystallised products on a heavy-wall Flask Filter and washing them with solvent from a Wash Bottle Lab.
- M.Sc. and research labs: filtering reaction mixtures and catalysts under suction.
- Analytical chemistry: gravimetric determinations where the precipitate is dried in the funnel.
- Pharmacy and QC labs: clarifying solutions and recovering solids.
Where no vacuum pump is available, a brass water-jet Vacuum Pump Filter can provide the suction. Grade 0 is the coarsest disc and grade 5 the finest; pick a coarse grade for bulky crystals and a fine grade for fine precipitates.
Standard Scope of Supply
Each funnel is supplied as a single unit with its sintered disc in the porosity grade and capacity you specify. A filter flask, rubber adapter and vacuum source can be quoted with the funnel if you are setting up a complete suction-filtration station for a teaching or research lab.
Packing, MOQ and Lead Time
Quotations are available for one funnel or for several capacities and grades for a whole teaching or research laboratory. Each states the packing, delivery time and price for the quantities listed, and other laboratory glassware from our range can be added.
Science Lab Supplies holds an Importer-Exporter Code as a registered exporter and can ship to buyers in Rwanda, South Africa, Qatar, Sri Lanka, Vietnam and Malaysia. A porosity grade, a capacity and a quantity are all a quote needs: send them through the contact page or the enquiry cart, and consult the lab tender page for formal tenders.
Frequently Asked Questions
Which porosity grade should I choose?
Use a coarse grade (0–1) for large crystals and fast flow, a middle grade (2–3) for general precipitates, and a fine grade (4–5) for very fine solids.
What capacities are offered?
The funnel is made in 35 ml, 80 ml, 200 ml, 500 ml and 1000 ml capacities, each across the porosity grades, so a lab can match the funnel to the batch size of each preparation.
How should the sintered disc be cleaned?
Rinse it in reverse with a suitable solvent straight after use so solids do not lodge in the pores, and avoid sudden temperature changes on the disc.
Who supplies the Buchner Funnel with Sintered Disc?
Science Lab Supplies handles the quotation and dispatch from Ambala, India, and can cover one funnel or a complete set of porosity grades for laboratories, universities and contractors.
