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
Important Safety Notice
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 is a Glass Buchner Filter Funnel used for?
A Glass Buchner Filter Funnel is commonly used in laboratories in conjunction with an air pump and filter bottle. It leverages the air pump to reduce pressure inside the bottle, working with a filter plate to achieve efficient solid-liquid separation, also known as vacuum filtration.
Q2: What types of Buchner Filter Funnels do you offer?
We offer two main types:
1. Buchner Filter Funnel with Glass Perforated Plate.
2. Buchner Filter Funnel with Fritted Disc, available in various porosity grades ranging from G0 to G6.
Q3: How do the different fritted disc grades (G0 to G6) differ?
The fritted disk aperture size follows the order: G0 > G1 > G2 > G3 > G4 > G5 > G6. The larger the number, the smaller the pore size. G0-G2 discs have coarser pores and allow natural filtration under normal pressure, while G3 and higher are designed for fine sediment filtration and work best under vacuum or suction pressure.
Q4: What material is used for these filter funnels?
They are manufactured from high borosilicate glass, which features a low coefficient of thermal expansion, high resistance to thermal fracture, and excellent chemical stability.
Q5: What are the precautions for vacuum filtration operations?
It is crucial to increase the pressure slowly during operation. Avoid sudden or violent pressure increases, as rapid pressure changes can easily damage the glass apparatus or lead to experimental failure.
