Integrity Tester

A Planova BioEX integrity test is performed to guarantee the filter’s integrity during the filtration process. The subsequent attributes enable the execution of a straightforward user integrity test at the user’s end: The membrane utilized in Planova BioEX filters is composed of hydrophilic modified polyvinylidene fluoride (PVDF), which enhances material strength and stability. Additionally, Planova BioEX filters undergo a variety of quality control tests during the production process to guarantee that each hollow fiber membrane is free of defects, particularly those resulting from gross defects such as broken fibers or pinholes or improper pore size distribution, which could potentially impact the filters’ virus removability.input:
output:The integrity test for Planova BioEX must be conducted twice by users: once prior to filtration to identify any potential gross defects that may arise during shipment, and again after filtration to identify any potential defects that may manifest during the filtration process.input:
output:The integrity test for Planova BioEX is a straightforward process that involves an air-diffusion-based test. This test can be conducted manually by visualizing pressurized air bubbling through the hollow fibers using the Visual Leakage Test method, or automatically by measuring the airflow through the hollow fibers using the Planova Leak Tester (for filters with an effective surface area size of 0.1 m2 or larger).
