Filter Funnel 50mm

The Filter Funnel 50mm is a laboratory funnel used for gravity filtration and controlled transfer of compatible liquids between laboratory vessels. Designed for chemistry, analytical and educational laboratories, it provides a simple way to support filter paper during solid-liquid separation and to guide liquids into containers with comparatively narrow openings.

Product Description

The STEMAids Filter Funnel 50mm is intended for routine laboratory filtration and liquid-transfer procedures. During gravity filtration, folded or conical filter paper is positioned inside the funnel so liquid can pass through while insoluble material is retained by the filter medium.

The supplied product designation specifies a 50 mm size. Whether 50 mm refers to the funnel bowl diameter or another dimensional parameter is . The exact material, stem length, stem diameter, funnel angle and glass grade are also . Explore complementary STEMAids laboratory glassware for complete laboratory setups.

How to Use the Filter Funnel 50mm

1. Inspect the funnel for cracks, chips, contamination or other visible damage before use.
2. Select filter paper appropriate for the funnel and intended filtration procedure.
3. Fold and position the filter paper correctly inside the funnel.
4. Support the funnel securely above a suitable receiving vessel.
5. Wet the filter paper with a compatible liquid when required by the procedure.
6. Pour the mixture gradually into the filter without exceeding the safe level of the filter paper.
7. Allow gravity to draw the filtrate into the receiving vessel and process the retained residue as required.

Safety note: Wear laboratory PPE appropriate to the substances handled. Do not use damaged laboratory ware, and confirm material and chemical compatibility before filtering corrosive, hot or reactive liquids.

Care & Maintenance

• Clean the funnel promptly after use with a method compatible with the substances handled.
• Remove residue from the stem carefully without using tools that could damage the funnel.
• Allow the funnel to dry fully before storage.
• Store it in a protected rack, tray or cabinet to reduce impact and breakage.

Frequently Asked Questions

What is a Filter Funnel 50mm used for?

A Filter Funnel 50mm is used for gravity filtration and controlled liquid transfer in laboratory work. With suitable filter paper, it can separate insoluble solids from a liquid.

What does the 50 mm size mean?

The product designation states 50 mm, but the exact dimensional reference is . It should not be described as a 50 mm bowl diameter until STEMAids verifies that specification.

What material is the filter funnel made from?

The exact construction material is . Glass or borosilicate glass should not be stated unless verified by the STEMAids product specification.

Can this funnel be used with filter paper?

Yes, filter funnels are designed to support suitable filter media during gravity filtration. The filter-paper diameter and grade should be selected according to the funnel dimensions and laboratory procedure.

Is the Filter Funnel 50mm suitable for school laboratories?

Yes. It is suitable for supervised practical work demonstrating filtration, residue, filtrate and liquid-transfer techniques.
