Product description
Filter integrity testing accessories are used to connect membrane filters, filter housings and integrity testing instruments during validation procedures. These accessories ensure safe and reliable connections between the tester and the filtration system.
Technical overview
During membrane filter integrity testing, various connection components are required to link the testing instrument to the filter housing or test setup. These accessories allow different filter configurations to be tested while maintaining controlled pressure conditions.
Typical accessories include test adapters, tubing sets, filter holders and connection fittings compatible with standard integrity testing equipment.
Operating principle
Integrity testing instruments apply controlled gas pressure to a wetted filter element in order to measure flow behaviour or pressure changes through the membrane.
Accessories such as adapters and tubing sets provide the physical connection between the instrument and the filter housing, ensuring that pressure is applied correctly and that the test conditions remain stable.
Proper connection components are essential for accurate and repeatable integrity testing results.
Material options
Integrity testing accessories are manufactured from materials compatible with filtration processes and laboratory environments.
- Stainless steel adapters and fittings
- Chemically resistant tubing materials
- Industrial-grade connection components
- Pressure-rated fittings
Material selection depends on the filtration process and the integrity testing method used.
Available micron ratings
Accessories themselves do not define filtration performance. They are used together with membrane filters and filter cartridges being tested during integrity validation procedures.
Typical filters used during testing include:
- 0.1 µm sterilizing grade membranes
- 0.2 µm sterile filtration membranes
- 0.45 µm clarification membranes
- Other membrane filters used in industrial filtration processes
Design and construction
Integrity testing accessories are designed for compatibility with standard filtration housings and testing equipment.
Typical components include:
- Filter housing adapters
- Test tubing sets
- Membrane filter holders
- Connection fittings and couplings
These components allow flexible connection between the integrity tester and different filtration systems.
Typical applications
- Membrane filter integrity testing
