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 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 used for?
It is primarily used in laboratories for filtering acidic liquids and other solutions. The sintered glass (fritted disc) acts as a built-in filter, eliminating the need for filter paper, which is especially useful when dealing with corrosive chemicals.
How do I choose between G0 to G6 fritted disc specifications?
The grade (G0 to G6) determines the pore size. G0 has the largest pores (100-160 microns) for coarse filtration, while G6 has the smallest pores (1.2-2.0 microns) for filtering extremely fine particles like bacteria. Choose based on the size of the precipitate you need to filter.
Do I need a vacuum pump for filtration?
For coarser grades like G0 to G2, natural gravity filtration works under normal pressure. However, for finer grades like G3 to G6, the water flow is very slow or non-existent under normal pressure, making pressure or suction/vacuum filtration necessary.
What chemicals should not be filtered with this glass funnel?
You should avoid filtering hydrofluoric acid, hot concentrated phosphoric acid, and hot or cold concentrated alkaline solutions, as these chemicals can chemically attack and damage the high borosilicate glass and the fritted disc.
How should I clean and maintain the fritted disc after use?
After use, filter with an appropriate washing solution, then soak the funnel in the cleaning solution for 48 hours. Rinse thoroughly with distilled water, filter again, and dry completely before storage to prevent sediment blockage.
Can I sterilize the glass funnel with a fritted disc?
Yes, sterilization can be achieved via autoclaving (high-pressure sterilization) before use. When heating or cooling during drying, ensure the temperature changes slowly, and never open the oven until it has cooled to room temperature to prevent thermal shock and explosion.
