Sintered Funnel 4″

A 4″ sintered funnel is a laboratory essential designed for efficient filtration of liquids and solids. It features a funnel body constructed from chemically resistant borosilicate glass, ensuring durability and resistance to a wide range of chemicals. The key component of this funnel is the sintered glass disc integrated at the base. This disc is produced by fusing glass particles to create a porous structure with a specific pore size. The pore size determines the size of particles the funnel can retain while allowing liquids to pass through.

Sintered funnels are commonly used in conjunction with a vacuum filtration setup. The funnel is placed on a receiving flask, and a vacuum is applied. The liquid sample is poured into the funnel, and the vacuum draws the liquid through the sintered glass disc, trapping solids on the disc’s surface. This process allows for the quick and efficient separation of liquids and solids.

4″ sintered funnels are particularly advantageous for:

• Filtering larger volume samples due to their increased diameter.
• Applications requiring the separation of fine particles due to the availability of sintered discs with various porosities.
• Safe handling of hazardous or corrosive chemicals due to the chemical resistance of borosilicate glass.

Here are some additional points to consider when choosing a 4″ sintered funnel:

• Porosity grade: Select a disc porosity that is appropriate for the size of particles you intend to retain.
• Capacity: Consider the volume of liquid you typically need to filter.
• Compatibility: Ensure the funnel material is compatible with the chemicals you will be using.
