Glass Funnel Manufacturer,Supplier and Exporter in India

Glass Funnel (Product Code: SLE/GF/01) is a conical, short-stemmed funnel in borosilicate glass for filtering mixtures through filter paper and for transferring liquids into narrow-necked vessels without spills. Offered in 75 mm, 90 mm and 120 mm diameters, it is a basic item of borosilicate laboratory glassware used in chemistry experiments at every level from secondary school to university. It is manufactured by Jain Scientific Equipments Pvt Ltd (ScienceLab), Ambala.

Specifications

Typical Use

For gravity filtration, a circle of filter paper is folded into a cone, seated in the funnel and wetted so it clings to the glass; the mixture is then poured down a glass rod onto the paper, with the stem resting against the inside wall of the receiving beaker or flask so the filtrate runs down smoothly. Separating sand from salt solution, collecting a precipitate and clarifying a solution before crystallisation are routine examples in school chemistry lab equipment sessions.

The short stem is less likely to clog with solids and is preferred for hot filtration, where a long stem can cool the liquid enough for crystals to form inside it. Choose the 75 mm funnel for small test-tube and beaker work, 90 mm for general practicals and 120 mm for larger volumes. Because it is borosilicate, the funnel can take hot solutions and most laboratory solvents.

Frequently Asked Questions

Which diameters are available?
75 mm, 90 mm and 120 mm.

What size of filter paper should I use?
Choose a paper that, once folded, sits just below the rim of the funnel so liquid cannot run over the edge of the paper. Contact us if you would like us to suggest paper for your funnel size.

What is the benefit of the short stem?
It clogs less easily with solids and reduces cooling of hot solutions, so crystals are less likely to block the stem during hot filtration.

Should I choose glass or plastic?
Glass is the choice for hot liquids and organic solvents. A plastic funnel is lighter and does not break, which suits younger students and cold aqueous work.

How do I clean it?
Rinse immediately after use, wash with laboratory detergent and a soft brush, and give a final rinse with distilled water before drying upside down.

Can you supply funnels in bulk for schools or for export?
Yes. Send the diameters, quantities and delivery location in India or abroad, and we will prepare a quotation.
