This is EASYCAGE™

The EasyCage is a disposable, recyclable (PET,) retrofittable caging option that works in conjunction with Allentown’s NexGen Mouse IVCs. Because it’s disposable, the EasyCage eliminates cage processes such as washing and autoclaving, streamlining vivarium operations while at the same time improving performance, bio-security, ergonomics, and energy consumption.
