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. Teachers, students and technicians in school, college and analytical laboratories use it daily. Science Lab Supplies ships it from Ambala, India to schools, colleges, testing laboratories, tender contractors and distributors.

Specifications

The 60° internal cone lets a standard folded filter paper sit flat against the glass for steady flow. Heavy walls and a reinforced rim add strength, the short uniform stem is less likely to clog or snap, and the clear glass shows the liquid level and any blockage at a glance.

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 most acids, alkalis and solvents used in teaching and analytical work.

• Class 9 science: separating mixtures by filtration.
• 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 rod, and keep the liquid below the paper's edge.

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

We quote for a single set or for enough sets to cover every bench in a laboratory. Each quotation 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 them.

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. Start with the contact page or the enquiry cart; if a tender is involved, the lab tender page sets out how we quote.

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.

Who supplies the Borosilicate Filter Funnel?
Science Lab Supplies supplies it from Ambala, Haryana, India to schools, colleges and analytical laboratories, and to contractors who buy glassware in bulk for them.

Related Filtration Glassware

Filtration needs a vessel underneath, a rod to guide the pour and, for quantitative or fine work, an alternative filter. These four items complete a filtration bench and are frequently ordered alongside the funnels for teaching and analytical laboratories.

• Borosilicate Conical Flask — collects the filtrate beneath the funnel.
• Glass Stirring Rod — guides the liquid onto the filter paper.
• Gooch Crucible — collects precipitates for gravimetric weighing.
• Millipore Filter Apparatus — vacuum filtration through membranes.
