As an end-to-end Solutions Provider, and a Partner in Research, Allentown will always go above and beyond to provide the industry with exactly what it needs. It's for this reason that we've once again extended the value of our NexGen family of products with the development of the NexGen MOUSE 900 IVC and Cage System! The NexGen Mouse 900 cage has the same, larger, 900 cm² floor space as its rat counterpart, but with a shorter height to provide your mice with the access they require to water and feed.


Smooth and easy sliding in, and the same sliding out...less stress and vibration for your animals and less repetitive motion strain on your staff... those are the benefits of NexGen's innovative plastic runner system. So innovative that the NexGen is changing the way animal care staff perform their wellness checks...they just slide their occupied cages out of their stalls 3/4 of the way and assess their animals. No need to fully remove cages from the rack...making animal observation simpler, easier and faster than ever before!


There's so little you'll hear when using a NexGen that it's easier to describe what you won't: no loud hum, no swirling fan, no air noise as it gets sucked into the blower intake...just quiet. Energy efficient ECM motors along with design expertise applied by Allentown airflow experts ensures you'll barely even notice that the blowers are on!


Lighter, smaller, easier to move and manipulate...that's the NexGen!
Reengineered to be stronger yet lighter, the NexGen uses less stainless steel and a combination of high-quality plastic materials to make the rack
easier to work with. Coupled with easy to assemble cage systems, working with the NexGen is a breeze!
