Filter Integrity Testing
Filter Integrity Testing
The MEM-TEST filter integrity tester is a cutting-edge innovation, co-developed by FSP Technologies and our associates in Germany. Designed for precision and reliability, it ensures efficient and compliant filtration validation across
For sterilizing-grade filtration, integrity testing isn’t optional — it’s how you prove a filter will do its job and satisfy the regulator. FSP provides complete filter integrity testing and validation support, both as a manufacturing standard on our own products and as a service to help you qualify filtration in your process.
Integrity tests we support
- Bubble Point Test (BPT) — determines the pressure at which the first steady stream of bubbles passes through a wetted membrane, confirming the largest pore and membrane integrity.
- Diffusion / Forward Flow Test — measures gas diffusion across a wetted membrane at a set test pressure to detect oversized pores or damage.
- Water Intrusion Test (WIT) — the standard non-destructive test for hydrophobic vent and gas filters.
- Pressure-Hold / Pressure-Decay — verifies system and filter integrity in plac
We offer both on-site and off-site testing services for convenience and reliability
