Borosilicate Filter Funnel

Product Code : SCL-LG-11997

Borosilicate Filter Funnel (SKU SCL-LG-11997) is a heavy-walled, short-stem glass funnel with a 60° cone, made of Borosilicate 3.3 glass, for separating solids from liquids through filter paper and for pouring liquids into narrow-necked vessels. It suits filtration and transfer work in school, college and analytical laboratories. Science Lab Supplies, from its Ambala base in Haryana, India, can quote and pack the funnel sets for schools, testing laboratories, tender contractors and distributors.

Specifications

Cone angle, glass, stem and set contents for the filter funnel are each given a row below. In short, the 60° internal cone lets a standard folded filter paper sit flat against the glass, heavy walls and a reinforced rim add strength, and the short uniform stem is less likely to clog or snap.

Applications and Experiments for the Borosilicate Filter Funnel

A glass filter funnel handles gravity filtration, the simplest way to separate an insoluble solid from a liquid, and doubles as a pouring aid for flasks and burettes. Borosilicate glass copes with hot solutions and the acids, alkalis and solvents used in teaching and analytical work.

• Class 9 science: separating mixtures by filtration into a Borosilicate Conical Flask.
• Class 11–12 chemistry: filtering precipitates and preparing crystals from solution.
• B.Sc. analytical chemistry: gravity filtration of precipitates on filter paper.
• Filling volumetric flasks and burettes without spills.

Moisten the folded paper so it seals against the cone, pour down a Glass Stirring Rod, and keep the liquid below the paper's edge. For suction work, seat the funnel with Rubber Stoppers with Holes.

Standard Scope of Supply

Each set comprises four short-stem borosilicate filter funnels, one cleaning brush for the funnel stems and one filtration user guide. Filter paper, funnel stands and receiving flasks are not included; they can be listed in your enquiry for quoting with the funnels.

Packing, MOQ and Lead Time

Quotations cover a single set or enough sets for every bench in a laboratory. Each one details packing, delivery time and price for the quantity you request, and matching flasks, stands and other chemistry lab equipment in India can be priced with the funnels.

Science Lab Supplies holds an Importer-Exporter Code as a registered exporter and is able to ship to buyers in Saudi Arabia, Oman, the Philippines, Nepal, Bangladesh and Zambia. Say how many funnel sets each bench needs on the contact page, add filter paper and stands to the enquiry cart, or open the lab tender page if the purchase is tendered.

Frequently Asked Questions

What is a borosilicate filter funnel used for?
It holds folded filter paper for gravity filtration, separating a solid from a liquid, and helps pour liquids into narrow-necked flasks and burettes without spilling.

Why does the 60° cone angle matter?
Standard filter paper folded into quarters forms a 60° cone, so it lies flat against the glass. That improves the seal and keeps filtration steady without liquid bypassing the paper.

How many funnels come in a set?
A set contains four short-stem funnels, a stem-cleaning brush and a filtration user guide. Filter paper and stands are ordered separately and can share the quotation.

Who supplies the Borosilicate Filter Funnel?
The funnel sets are offered by Science Lab Supplies, an Ambala firm that quotes them for schools, colleges and analytical laboratories as well as for contractors buying glassware in bulk on their behalf.

Related Funnels, Stands and Filtration Items

Filtration needs a paper, a support for the funnel, a vessel underneath and, for faster or finer work, an alternative funnel or a vacuum flask. The items below from the glassware, funnel and chemistry ranges complete a filtration bench and can be quoted with the funnel sets.

• Filter Paper — 120 mm diameter paper for clarifying liquids and qualitative separations.
• Funnel Filtering, 60° angle with stem — offered in diameters from 25 mm to 125 mm.
• Long stem Funnel — 60° bowl with a stem of about 150 mm and 8 mm outer diameter.
• Funnel Holder — polypropylene holder for funnels of 3 to 6 inches on 1/2 or 3/8 inch rods.
• Funnel Stand — hardwood stand with slotted funnel holders and cork-lined clamps.
• Flask Filter — heavy-wall flask printed in white enamel without graduation, 100 to 5000 ml.
• Buchner Funnel Fritted Disc — coarse, medium or fine porosity, 2 ml to 3000 ml.
• Gooch Crucible — retains a precipitate for washing and weighing in one vessel.
