E Rapid Transfer Port (ERTP) for Processing

June 1, 2023
Central Research Laboratories' (CRL) newest rapid transfer port offers easier maintenance, more space, one-handed-use, and better containment.

A new model in the Rapid Transfer Port product family, the E Rapid Transfer Port (ERTP) uses the exact Double-Door Transfer System as the other transfer port models but offers an access door that allows one-handed use, a 45-deg. handle-turn radius, easier maintenance, and compatibility with common beta-flange systems.


The design includes a new handle that uses minimal rotation to break the seal on the beta container, reducing operator effort for safer handling. It also features a streamlined interlock system with interchangeable beta mounts that can be replaced without breaking containment. The design has also been improved to eliminate exposed fasteners and incorporates a smoother surface for easier cleaning.


The interlocks are incorporated into the Alpha flange and interface with the alpha port door handle to prevent:

  • The Alpha port door from being opened when a Beta flange has not been docked
  • The Beta flange from being removed from the Alpha flange when the Alpha port door is open
  • The Alpha port door handle from being rotated when the door is open

Available sizes: 4, 7, 11, and 14 in. (105, 190, 270, and 350 mm)

  • Easily operated with one hand
  • Minimal moving parts for fewer maintenance concerns
  • 45-deg. handle turn radius frees up space inside isolator
  • Standard sizes available for retrofits
  • DPTE Getinge-style beta compatible
