AT-Port

Aseptic liquid transfer across critical environments

Aseptic liquid transfer is a critical yet complex step in pharmaceutical and biotech manufacturing, especially when moving products between areas with different containment levels.

The AT-Port System is an alpha-beta aseptic connection solution designed to ensure safe, sterile, and efficient liquid transfer across barriers such as isolators or RABS. By maintaining Grade A conditions throughout the transfer, it eliminates contamination risks, reduces validation complexity, and minimizes product loss—addressing key industry challenges in sterility, process reliability, and high-value product handling.

AT-Port System

The AT-Port System is an alpha-beta aseptic liquid connection system, enabling safe liquid transfer between different containment classification areas, across a wall, while maintaining sterility.
It consists of the :

  • Connector Port
  • Disposable Connector Devices, AT-Connector and AT-Connect

Transfer larger volumes: AT-Connector

  • For large volumes liquid transfer between two different classification environments
  • Same connector can be used up to 5 opening-closing operations
  • Hose barb connections
  • Supplied sterilized or non-sterilized for RTU assembly
  • Distributed worldwide by Sartorius Stedim under brand name Gammasart Aseptic Transfer Device (ATD™)

When every drop matters: AT-Connect

  • Aseptic liquid connector device used with AT-Port System
  • For optimal high-value bulk product introduction to the aseptic filling line, installed on isolator or RABS.
  • Efficient low volume transfer
  • Product contact with silicone and thermoplastic elastomer (C-Flex®) tubing only: tube passes through the disposable connector device
  • Enables placement of the dosing system outside of the containment

Advantages

  • Ergonomic design
  • 100% leak-test of the system
  • Small footprint
  • Connection is made in seconds
  • Ensuring grade A continuity
  • Error-proofing with security features
