Automated integrity test system for sterile gas and vent filters
The palltronic AquaWIT XC integrity test system offers major benefits for integrity testing of hydrophobic gas filters.All stages of the water intrusion test (WIT) can now be performed fully automatically on gas filters, and online.The operator simply connects the palltronic AquaWIT XC system to the filter system, inputs test parameters on the easy to use touchscreen and starts the test sequence.The filling, testing, draining and drying is performed without further operator involvement and a detailed test result is saved and printed.With 颇尔's direct flow measurement technology and a hydraulic bridge link to the test filter, accurate and reproducible results are ensured even during changes in environmental temperature.
Accuracy and Reliability
In validation studies, flow was measured at different environmental temperatures using a small filter with a typical water intrusion flow rate of 0.04 mL/min to represent worst case conditions.Even under conditions where the environmental temperature of the filter as 20 °C (36 °F) higher than water temperature, an accurate test result was obtained.Validation work has also shown that accurate measurements can be performed using filter installations at a distance of at least 10 m (33 ft) and a height of 2.5 m (8 ft) or more.颇尔 can assist in qualifying the palltronic AquaWIT XC integrity test system for individual purposes.
Hydraulic Bridge
The hydraulic bridge removes all air from the upstream filter system and tubing.Flow measurement is then performed in a more controlled environment within the palltronic AquaWIT XC integrity test system.Stable results can be obtained even when environmental temperatures are changing by 10 °C (18 °F) or more.Direct flow and real time measurement further adds to the accuracy, speed and reliability of the test result.
多功能
The palltronic AquaWIT XC integrity test system has been designed to test vent filters in positions with difficult access where environmental temperatures may be fluctuating.The hydraulic bridge permits the water intrusion test to be performed on:-
Filters in elevated positions, for example, product storage and WFI tanks
-
Filters which are inside equipment, for example lyophilizers or sterilizers which are difficult to access
-
Several different filter installations testing from a fixed point
