fritted disk

A fritted disk, also known as a porous frit, is a piece of glassware that is commonly used in laboratory settings for filtration and gas dispersion. It is made of a piece of glass that is packed with tiny, porous glass particles or beads.

The pores in the fritted disk act as small filters, allowing liquid or gas to pass through while trapping larger particles or contaminants. This makes it useful for separating solid particles from liquids or gases, as well as for purifying gases.

Fritted disks come in a variety of sizes and porosities, depending on the application they are being used for. They are commonly used in chemistry, biology, and other sciences where filtration and gas dispersion are necessary.
