FAQs

A1: It is primarily used for vacuum filtration in laboratories. When connected to a vacuum pump and a receiving flask, the negative pressure pulls liquid rapidly through the fritted disc (or filter paper on the glass plate), efficiently separating solid crystals or impurities from the liquid solvent.

A2: These numbers represent the standard taper size of the ground glass joint at the bottom of the funnel. You must choose the size that perfectly matches the inner ground joint diameter of your receiving Erlenmeyer flask (e.g., a 24/40 flask requires a 24# funnel) to ensure an airtight seal.

A3: No, that is the main advantage of a fritted disc! The porous glass sand core acts as the filter itself, catching fine particles while letting liquid through. However, if you choose the “Perforated Glass Plate” model, you must place a properly sized circular filter paper flat against the plate before starting the vacuum.

A4: Yes. Because the entire funnel and the fritted disc are made of pure Borosilicate 3.3 glass, it is highly resistant to chemical corrosion. You can soak it safely in strong acids (like aqua regia or piranha solution) to dissolve trapped organic compounds and restore the flow rate of the pores.
