Utilizing proven technology to safely transfer materials in sterile and hazardous environments.

50 years ago, CRL introduced the Double Door Transfer System to the Nuclear industry. Striving to be a continued leader in industry technology, CRL continues to build upon this proven technology to develop innovative products used for rapid and repeatable transfer of materials. At present, CRL transfer products have found use in both Nuclear and Life Science applications for safe and reliable material transfer needs.

The CRL Transfer System consists of two main components, the Alpha flange and the Beta assembly. The Alpha flange is typically mounted in an isolator or glovebox wall, and the Beta assembly is mobile and used to transfer the materials. When the two assemblies are mated, materials can be rapidly transferred into and out of an environment without breaking containment.

CRL manufactures Transfer Systems used in various Nuclear and Life Science applications to accomplish:

  • Transfer of hazardous or sterile material from one sealed enclosure to another sealed enclosure
  • Safely perform transfer without contaminating the sealed enclosures or the environment surrounding the sealed enclosures

Alpha Flange

CRL Alpha flanges are available in various configurations, from 105mm to 460mm sizes. Ports are typically constructed of stainless steel and have optional door materials available to provide flexibility for various application needs.

Interlock System

The CRL Rapid Transfer Port (RTP) features mechanical interlocks that prevent the improper operation of the transfer port which can compromise the containment and sterility of the barrier/isolator.

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

RTP Flexible Mounts

For use where connection alignment is difficult CRL Rapid Transfer Ports can be used with flexible membrane mounts and rotating alpha or beta flanges to enable the connection of large containers or process.
