Pharmaceutical manufacturers must achieve sterility because it protects patient safety while following regulatory standards. Aseptic processing depends on sterile filtration as its main component which needs exact instrumentation for validating its operational performance. The filter integrity tester serves as an essential tool for this process.

MedIntegrity operates as a reliable provider which manufactures testing instruments in the United States for pharmaceutical applications. The Filter Integrity Tester V8.0 and Filter Integrity Tester V6.5 products from MedIntegrity solve the intricate testing requirements that GMP facilities need across different countries.

 

Role of Filter Integrity Testing in Sterile-Filtration Validation

Ensuring Compliance with Regulatory Standards

The FDA and EMA and WHO already have strict standards in place which you probably know about. The agencies need validated filter integrity testing to verify that sterile filters used in aseptic processing remain effective.

Verify that all required documents for the filter integrity tester include the user manual and technical specifications and installation drawings and calibration certificates. The documents verify that your testing device fulfills all required performance standards and regulatory requirements. MedIntegrity instruments follow FDA 21 CFR Part 11 and USP and EP and GMP regulations which provides you with assurance during inspection or audit activities.

Verifying Sterility Assurance Before and After Filtration

The process of filter integrity testing which occurs before and after filtration serves to protect sterility assurance levels (SAL). The filter needs to show complete integrity before application because any breach would allow bacteria to enter while post-processing tests verify that the filter remained functional during all processing steps.

Perform multiple tests of the filter integrity tester on one filter under identical conditions to verify its testing consistency. The filter must produce identical results during testing because this proves its ability to support sterility assertions. The V8.0 model enables you to store 1000 pre-programmed tests and shows real-time test curves which improves your ability to verify filter performance.

Supporting Risk-Based Validation Approaches

A contemporary filter integrity tester produces more than pass/fail results because it creates measurable data which helps you determine process validation risk assessment levels.

The filter integrity tester requires testing with various filter types which include filters made from different materials and filters with different pore sizes and configurations. The testing capability enables risk-based validation approaches to assess different membrane types based on their individual risk levels. MedIntegrity provides intelligent software and analytics modules which enable you to identify patterns and create reference points for making better choices.

Key Features That Define an Effective Filter Integrity Tester

Precision and Sensitivity of Measurement Systems

The fundamental operation of any filter integrity tester depends on its ability to deliver precise measurement results. The system detects all product safety-threatening defects through its exact measurement of bubble point and diffusion flow and pressure hold values.

Standard filters with established integrity properties should be used to evaluate the performance of the filter integrity tester. The validation process verifies that your instrument maintains its high sensitivity during multiple testing runs. The V8.0 model includes precise pressure sensors which enable users to perform bubble point tests and diffusion flow tests and pressure holding tests with tight tolerance settings.
