Buchner Funnel Fritted Disc
Product Code : LSK-LF-10388
Buchner Funnel Fritted Disc (SKU LSK-LF-10388) is a filter funnel with a built-in fritted (sintered) disc, used for suction filtration without filter paper. It is offered in coarse, medium and fine porosity and in nine capacities from 2 mL to 3000 mL. It suits college chemistry labs, research groups and pharmacy departments that collect crystals and precipitates. Each quotation for it is issued by Science Lab Supplies in Ambala, India, to colleges, schools, institutes, tender contractors or distributors.
Specifications
Porosity grades, all nine capacities and the construction details of the fritted funnel are given in the table. In short, it has a thick wall, a beaded rim and white colour enamel printing, and its coarse, medium or fine disc lets you match pore size to the solid, across capacities from 2 mL to 3000 mL.

Applications and Experiments for the Buchner Funnel Fritted Disc
The fritted Buchner funnel is fitted to a filter flask and connected to vacuum, so liquid is drawn through the disc while the solid stays on top for washing and drying. It suits organic and inorganic preparations, gravimetric work and pharmaceutical chemistry practicals in college and research laboratories.
- B.Sc. organic chemistry: collecting and washing products such as acetanilide after recrystallisation from a Round Bottom Flask, Wide Neck.
- B.Sc. and M.Sc. inorganic chemistry: isolating prepared complexes and salts, then drying them on a Watch Glass.
- B.Pharm pharmaceutical chemistry: filtering synthesised compounds.
- Analytical and research labs: filtering solutions where filter paper fibres must be avoided.
Use a thick-walled filter flask rated for vacuum, release suction slowly, and clean the disc promptly so its pores do not clog.
Standard Scope of Supply
The Buchner Funnel Fritted Disc is supplied as a single funnel in the capacity and porosity you specify. A filter flask, an adapter or rubber cone and a vacuum source can be added to the same quotation, so the complete suction filtration set can arrive together.
Packing, MOQ and Lead Time
Quotations can be issued for one funnel or for a set across several capacities and porosities. Each one states the packing, delivery time and price for the quantities requested, and filter flasks or other laboratory glassware can join the same quotation.
Being a registered exporter with an Importer-Exporter Code, Science Lab Supplies can ship to buyers in Tanzania, Uganda, the UAE, Saudi Arabia, Oman and the Philippines.

State the capacity and porosity on the contact page or in the enquiry cart to receive a price, and see the lab tender page if a tender governs the purchase.
Frequently Asked Questions
Which porosity should I choose?
Coarse suits large crystals and fast flow, medium is a general choice for most precipitates, and fine retains small particles but filters more slowly. State the porosity with the capacity when you order.
What capacities are offered?
Nine capacities are offered: 2, 15, 30, 60, 150, 350, 600, 2000 and 3000 mL, covering micro-scale work through to large preparations. Name the porosity alongside each capacity when you enquire.
Who supplies the Buchner Funnel Fritted Disc?
Quotations for this funnel are prepared by Science Lab Supplies at Ambala, India, line by line for each capacity and porosity, for colleges, research labs, contractors and distributors.
Does it need filter paper?
No. The fritted disc itself is the filter medium, so the funnel is used without paper. Clean the disc after each use so its pores stay open.
