✓ Engineered for Absolute Process Integrity
At R+F FilterElements GmbH, we understand that sterile filtration is a critical safety barrier in your production. Our sterile filter elements are specifically engineered for high-stakes pharmaceutical applications and rigorous sterilization tasks.
To ensure maximum safety, all our elements are manufactured in strict accordance with HIMA (Hygienic Industry Manufacturers Association) regulations. We don't just meet industry norms; we aim to exceed them, ensuring that every element achieves its intended specifications for particle retention and microbial safety.
🔬 Validated Quality – Tested to Perfection
Product quality is the cornerstone of our manufacturing process. Every R+F sterile filter element undergoes a multi-stage quality control protocol:
- Material Validation: Comprehensive test reports are generated for all raw materials before production begins.
- In-Process Control: Continuous monitoring during the manufacturing phase ensures structural integrity.
- 100% Integrity Testing: Before packaging, every single sterile filter undergoes a rigorous inspection in accordance with EN 1822. This guarantees that only flawless, fully functional elements leave our facility.
📋 Full Traceability for Your Peace of Mind
In regulated industries, documentation is as important as the product itself. R+F FilterElements provides a seamless paper trail for every component:
- Unique Identification: Each filter element is laser-marked with a unique Batch ID, allowing for 100% traceability from the raw material to the point of use.
- Global Standards: Our testing methods adhere to the most stringent international standards, including EP, HIMA, FDA, ISO, and ASTM D 2986-91.
- Certification Included: Every packaging unit includes a "Works Inspection Certificate" (DIN EN 10204). This custom report details the individual integrity test results, providing you with the necessary documentation for your quality management system.
- Operational Support: Each unit is delivered with a comprehensive operational manual to ensure correct handling and maximum filter life.
