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
Important Instructions:
The newly purchased filtering instrument needs to be filtered with acid solution before use, washed clean with distilled water, and dried before use. For sterilization filters, high-pressure sterilization is required before use. After use, a washing solution should be used for filtration, and then soaked in the washing solution for 48 hours before being taken out and rinsed with distilled water, filtered, dried, and stored. During the drying process, do not open the oven halfway. Wait until the oven has cooled to room temperature before opening and removing it to prevent explosion. After use, it is necessary to wash it to avoid affecting the filtration efficiency due to sediment blockage. Attention should be paid to slow heating or cooling, and it is not advisable to filter hydrofluoric acid, hot concentrated phosphoric acid, hot or cold concentrated alkaline solution during use.
Frequently Asked Questions (FAQ)
What is a glass funnel with a fritted disc?
It is a laboratory filtering instrument featuring a sand core filter plate made of sintered glass. It is commonly used to filter acid liquids and is also known as an acid-resistant funnel or glass vertical melting funnel.
What do the G0 to G6 specifications mean?
These specify the aperture size of the fritted disc. The larger the number, the smaller the aperture. For example, G0 has the largest pore size (100-160 microns) for coarse filtration, while G6 has the smallest (1.2-2.0 microns) for filtering bacteria.
When should I use suction or pressure filtration?
For finer specifications like G3, the water output under normal pressure is very slow or may not flow at all. It is highly recommended to combine the process with pressure or suction filtration for effective results. Coarser discs like G0 to G2 can be naturally filtered under normal pressure.
What materials are filtered funnels with fritted discs made of?
They are made of high-quality high borosilicate glass, which ensures a low thermal expansion coefficient, high transparency, and exceptional fracture stability.
How should I prepare a new fritted funnel before its first use?
Before the first use, you should filter the instrument with an acid solution, wash it clean with distilled water, and dry it. If it is being used as a sterilization filter, high-pressure sterilization is required prior to use.
What chemicals should not be filtered using this funnel?
During use, you should avoid filtering hydrofluoric acid, hot concentrated phosphoric acid, and both hot or cold concentrated alkaline solutions, as these can damage the glass and the fritted disc.
