Product Introduction:
Filter funnel is often used in conjunction with an air pump and filter bottle, it uses the air pump to reduce the pressure in the filter bottle, combined with the filter plate, to achieve solid-liquid separation. Also known as vacuum filtration or vacuum filtration.

Specifications and Lntroduction of Fritted Disc
As shown in the figure: the fritted disk aperture G0>G1>G2>G3>G4>G5>G6. The larger the number, the smaller the aperture. The commonly used ones are G2/G3 fritted disk, G3 is used to filter out fine sediment. Under normal pressure, the water output is slow or non-existent, and it is more effective when combined with pressure or suction filtration. G0-G2 fritted disk, due to its coarse pore size, can be naturally filtered under normal pressure.

Precautions
The pressure needs to be slowly increased, please do not suddenly increase the pressure violently, as increasing the pressure too quickly can easily cause product damage or experimental failure.
Frequently Asked Questions (FAQ)
Q1: What materials are used to make the Glass Buchner Filter Funnel?
A: The funnels are manufactured from high borosilicate glass, which provides a low coefficient of thermal expansion, high resistance to thermal fracture, and excellent chemical durability.
Q2: What is the main difference between the two types of Buchner funnels?
A: The Buchner Filter Funnel with Glass Perforated Plate uses a flat, perforated glass plate requiring filter paper. The Buchner Filter Funnel with Fritted Disc integrates a porous glass filter plate (available in grades G0 to G6) that can filter particles directly without paper.
Q3: How do I choose the correct fritted disc grade (G0 to G6)?
A: The grades are classified by pore size where G0 is the largest and G6 is the smallest. Coarse pore sizes (G0-G2) allow natural gravity filtration, while finer grades (like G3 to G6) are designed to filter fine sediments and require vacuum or suction filtration.
Q4: What capacity sizes are available for these funnels?
A: The product specifications range from 30ml up to 2000ml for the fritted disc type, and 30ml to 1000ml for the perforated plate type, meeting various lab scale requirements.
Q5: Can I increase the filtration pressure quickly to speed up the process?
A: No. The pressure must be increased slowly. Sudden or violent pressure changes can cause damage to the glass assembly or lead to experimental failure.
