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 Precautions:
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)
Q1
What material is the Glass Funnel with Fritted Disc made of?
It is made of high-quality high borosilicate glass, which provides a low thermal expansion coefficient, high transparency, and strong fracture stability.
Q2
What is the purpose of the sand core filter plate (fritted disc)?
The fritted disc is made of sintered glass material designed to filter acid liquids and handle acid treatments. It is also known as an acid-resistant funnel or glass vertical melting funnel.
Q3
How do I choose between different fritted disc specifications (G0 to G6)?
The aperture size decreases as the grade number increases (G0 > G1 > G2 > G3 > G4 > G5 > G6). G0-G2 have coarser pores for natural filtration under normal pressure, while G3-G6 have finer pores for filtering out fine sediment or bacteria, which are more effective with pressure or suction filtration.
Q4
How should the glass funnel be prepared before its first use?
Newly purchased filtering instruments should be filtered with an acid solution, washed clean with distilled water, and thoroughly dried before use. For sterilization filters, high-pressure sterilization is required before use.
Q5
What is the cleaning and maintenance procedure after use?
After use, filter the funnel with a washing solution, then soak it in the washing solution for 48 hours. Afterward, rinse with distilled water, filter, dry, and store to avoid sediment blockage and maintain filtration efficiency.
Q6
What chemicals and conditions should be avoided when using this funnel?
You should avoid rapid heating or cooling. It is not advisable to filter hydrofluoric acid, hot concentrated phosphoric acid, or hot/cold concentrated alkaline solutions, as these can damage the fritted disc structure.
