The Palltronic® AquaWIT IV Filter Integrity Test System and MUX Extension

With the Water Intrusion Test (WIT) fast becoming the in situ integrity test of choice for hydrophobic filters, the Palltronic AquaWIT IV system is the latest in the line of Pall’s state-of- the-art products developed specifically to perform crucial filter integrity testing - accurately, reproducibly and reliably. The system fills the housing of a hydrophobic filter with water, performs a Water Intrusion Test, then drains the housing. A new feature to this latest version of the Palltronic AquaWIT system is the option to wet hydrophilic liquid filters with water prior to integrity testing by the Forward Flow or Bubble Point test. A clear and well-defined wetting procedure that uses minimal water can be of real benefit for the pre-use testing of filters, for example in Allegro™ single-use systems.
