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
Q: What is the main application of a Glass Buchner Filter Funnel?
A Buchner filter funnel is commonly used in laboratory settings in conjunction with an air pump and a filter bottle. It leverages vacuum pressure (suction filtration) to achieve rapid and efficient solid-liquid separation.
Q: What types of Buchner Filter Funnels do you offer?
We offer two primary types: 1. Buchner Filter Funnel with a Glass Perforated Plate, and 2. Buchner Filter Funnel with a Fritted Disc (available in grades G0, G1, G2, G3, G4, G5, and G6).
Q: How do the different fritted disc grades (G0 to G6) compare?
The pore size of the fritted disk follows the sequence G0 > G1 > G2 > G3 > G4 > G5 > G6. The larger the number, the smaller the aperture. Coarser grades like G0-G2 can filter under normal pressure, while finer grades like G3 are optimal for fine sediments and work best with vacuum suction.
Q: What material is used to manufacture these funnels?
Our Buchner filter funnels are constructed from high borosilicate glass, which provides a low coefficient of thermal expansion, high resistance to thermal shock, and excellent structural stability.
Q: What precautions should be taken during vacuum filtration?
The pressure must be increased gradually. Do not apply sudden, violent pressure changes during the experiment, as rapid pressure fluctuations can damage the glass instrument or cause filtration failure.
