In many corrosive or sensitive process media straining applications,
plastic is the preferred material of construction for a basket strainer. Moulded
basket strainers are resistant to a wide variety of corrosive acids and other
aggressive materials. They will work in applications that may require a much
more expensive exotic alloy if one were easily available. Their plastic
constructions ensure that they will not contaminate sensitive process media
such as photographic chemicals and de-ionized water.
