Classic Alpha Port

With ABC Transfer, opening an Alpha Port from inside a machine has never been so easy. Regardless of its position on the isolator, the ABC Transfer® Alpha Port can be opened and closed with no effort.

Your health and safety managers are happier and your quality managers have one less problem to worry about during inspection.

  • A unique opening and closing system
  • Lighter than conventional RTP, the gloveless Alpha Port is a dream come true.


Gloveless Alpha Port… a dream come true

Although the idea of opening an Alpha Port from the outside of an isolator is not new, the innovative and simple approach adopted by ABC Transfer is. This is possible because we have gone back to the drawing board to design our Alpha Port.

  • Reduced risks of particulate or biological contamination aligned with GMP
  • Simplified validation process
  • More ergonomic process
  • Possibility to upgrade a Classic Alpha Port to a Gloveless Alpha Port

Double-wall isolator assembly

The introduction of double-wall isolators, particularly glass wall isolator, has provided customers with many operational and regulatory benefits. Conventional RTPs were designed before this isolator technology existed.

ABC Transfer has designed its rapid transfer port range to be integrated into double-wall as well as on single-wall isolators.
