Maintaining sterility during material transfer is one of the biggest challenges in pharmaceutical manufacturing—and a critical focus of the revised EU GMP Annex 1. With contamination risks highest when moving materials into cleanrooms and critical zones, it’s no surprise this remains a common area of non-compliance during inspections.

At AnalytiChem, we help you strengthen your contamination control strategy with validated solutions designed for aseptic workflows. Our Redipor® range of ready-to-use media, with a variety of packaging solutions, support sterility assurance from transfer to sampling, helping you meet Annex 1 expectations with confidence.

Material transfer remains one of the most vulnerable steps in sterile production. AnalytiChem offers innovative packaging solutions to help safeguard sterility during handling and transportation:

Redipor BetaBag - facilitates the safe transfer of ready-to-use gamma-irradiated prepared media, into your sterile manufacturing environment.

• Compatible with isolators and RABS using the Getinge La Calhène DPTE® Alpha Port
• Fully validated and guaranteed transfer process
• Significantly reduced risk of biological and particulate contamination
• Eliminating requirements for vaporised hydrogen peroxide (VHP) decontamination

• Validated sterility - irradiated for assurance against microbial contamination.

Redipor TwistLock Plates – Ready-to-use plated media with locking lids, to maintain sample integrity and prevent accidental exposure

Vapourised Hydrogen Peroxide (VHP) Resistant Packaging - Protects media from exposure to sterilants during decontamination cycles.

• Aperture for hanging: A hole at the top of the pack allows sleeves to be conveniently suspended for effective VHP distribution
• Validated performance: Tested at peak VHP concentrations with no ingress detected
• Easy access: Barrier film tears open effortlessly to maintain aseptic technique

Triple- and Double-Wrap Packaging Formats – Enable seamless transfer through cleanroom classifications.

Validated packaging supports effective disinfection and robust sterility, keeping you aligned with Annex 1’s focus on contamination control.

Beyond packaging, we also offer customised, ready-to-use media solutions tailored to your requirements:

• Plates, bottles, and bags in formats that fit your workflow
• Prepared under strict quality standards for reliable sterility
• Designed to reduce preparation time and minimise contamination risks

Whether you need standard formulations or bespoke solutions, our Redipor media ensures consistent microbial control across your processes.

Pair our media with environmental monitoring tools like SAS air samplers (available in Europe) for a holistic approach to Annex 1 compliance. Together, these elements form a strong foundation for sterility assurance in your facility.

Our experts can help you design a bespoke solution that meets your unique manufacturing and regulatory needs*.
