Application

Liquid transfers for pharmaceutical processes

  • For pharmaceutical filling

    Designed for liquid transfer in environments with the highest sterility requirements, including transfers between ISO 8 and ISO 5 classified areas.

  • For biotech and ATMP manufacturing

    The transfer of advanced products such as ATMPs, including cell and gene therapies, can also be reliably handled using the AT-Port system.

  • For integration into isolators

    The AT-Port system can be integrated into isolators and Restricted Access Barrier Systems (RABS). It is compatible with all SKAN isolators.

  • For high-containment applications

    Enables safe liquid transfer when handling hazardous or highly potent substances, protecting both operators and the product.

Aseptic liquid transfer with AT-Port System

  • 1

    Connect to bulk container

    Connector single-use system is attached to the bulk container and locked into the external wall port between containment zones.

  • 2

    Secure connector cover

    From the higher-grade area (e.g., ISO 5), the connector cover is secured inside the internal port. Rotation opens the beta part under controlled conditions.

  • 3

    Uncover connecting tube

    The connecting tube is safely exposed only inside the higher-grade chamber, preserving aseptic integrity.

  • 4

    Aseptic connection and transfer

    Sterile connection is established, and liquid transfer begins immediately. The entire sequence is fast and precisely controlled, minimizing contamination risk.

    Built-in safety

    Interlock mechanisms prevent accidental exposure or improper operation, ensuring protection even in high-containment use. The beta part cannot be opened without the connector single-use system (SUS) in place, and the SUS cannot be removed unless the beta part is closed.

    Broad versatility

    Applicable in sterile pharmaceutical operations and when handling highly potent or hazardous substances.

FAQs

  • The AT-Port enables aseptic or high-containment liquid transfer across containment zones (e.g., ISO 8 to ISO 5), preventing sterility and toxicity breaches.

  • The alpha-beta design maintains Grade A conditions. Safety interlocks prevent accidental disconnection or exposure. Each connector single-use system is leak-tested for integrity.

  • Yes, each connector single-use system allows up to five validated connections with the AT-Port. The system supports both conventional and single-use setups and is compatible with AT-Connect and AT-Connector.

  • Yes. SKAN offers full life-cycle support, including requalification, spare parts, troubleshooting hotline, and engineering services such as simulations and customized solutions.
