Animal caging and biological storage systems
First Claim
1. An isolation container comprising:
- a base which supports a plurality of sides;
a top affixed to the sides forming a microisolation container suitable to house a heat load;
one of said sides having an intake port with a filter membrane;
a second of said sides having an exhaust port with a filter membrane;
said exhaust port being located higher relative to the base than the intake port on an opposite side, thereby facilitating a convection based air flow from the intake port, across the container, and out the exhaust port.

Abstract
A novel microisolation container for laboratory animals or other species includes a rectangular, transparent base containing an intake port at the lower front end and a detachable top sealingly attached to the base which contains an exhaust port in the end opposite the intake port. The intake and exhaust ports are preferably covered with a filter membrane which excludes airborne contaminants. The interior of the top is contoured to provide a domed sloping ceiling for the container, the lower portion being adjacent the intake or front end of the container and the upper portion being adjacent the exhaust or rear end. Preferred embodiments include a feeder assembly which is supported by perforated supports which serve as shelter for the animals. The front and rear ports, the contoured ceiling and the feeder design aid in the laminar flow of air through the cage. A perforated floor, absorbent insert and disposable waste bag can be included in the base of the cage.
