Patent ID: 8807084

Claim:
An animal handling system for use in an MRD comprising a first input port and a second input port, said animal handling system comprising: a first elongated enclosure having a proximal end, an open distal end and a first geometry having a first cross-sectional area; and a second elongated enclosure having a proximal end, a distal open end and a second geometry having a second cross-sectional area smaller than said first cross-sectional area, wherein said first elongated enclosure is insertable into said first input port and said second elongated enclosure is insertable into said second input port and said second elongated enclosure is slideably insertable into said first elongated enclosure through said open distal end of said first elongated enclosure, and wherein said proximal end of said first elongated enclosure is sealed against a circumferential edge of said first input port and said proximal end of said second elongated enclosure is sealed against a circumferential edge of said second input port, thereby sealing the first and second elongated enclosures from the outside environment.
