Specifications and Introduction 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)
What is a Glass Buchner Filter Funnel used for?
It is primarily used in vacuum or suction filtration setups combined with an air pump and filter flask to separate solids from liquids efficiently.
What is the difference between the perforated plate and fritted disc types?
The perforated plate type features built-in holes and typically requires filter paper. The fritted disc type utilizes a porous glass disc (G0 to G6) that allows direct filtration without necessarily requiring filter paper, depending on the pore size.
How do I choose the correct Fritted Disc pore size (G0 to G6)?
The larger the G-number, the smaller the aperture. G2 and G3 are standard for fine sediments and work best under suction filtration. G0 to G2 have coarser pores and can filter liquids under normal gravity pressure.
Why is borosilicate glass used for these Buchner funnels?
High borosilicate glass offers a low coefficient of thermal expansion, outstanding thermal shock resistance, and high chemical stability, making it highly durable for laboratory operations.
Can I apply high pressure immediately during filtration?
No, the pressure must be increased gradually. Sudden changes in pressure can lead to structural damage of the glass funnel or failure of the filtration process.
