Filtech Grade 222 has medium flow rate and good particle retention and is the most commonly used acid-washed filter.
This grade covers a wide range of general ashless filtration applications. It is used for graviimetric analysis of numerous components (e.g.: cements, copper clay, bismuth, silicon, iron) found in heavy industries such as construction, mining or steel.
It is also used as a high purity filter for speedy filtering of trace elements such as silver chromate, lead sulphate, zinc and ammonium hydroxides. It is also found in general soil analysis for separating solid from aqueous extracts.
