Abstract: An automatic cage lock for securing various cages in a ventilated cage and rack system. The automatic cage lock facilitates the securing of a cage within the cage and rack system when a user slides the cage into the cage and rack system until the cage fully passes the locking finger component of the automatic cage lock. The cage may be easily unlocked by applying a small amount of pressure to the locking finger while simultaneously grasping the cage for removal. A color-coded indicator block may be disposed on the end of the lock assembly; the indicator block may be hidden by an indicator shield when the cage is securely docked in the rack. Conversely, the indicator block may be visually exposed when a cage is present in the rack but not fully docked within the rack. The indicator block provides a clear indication to a user as to the docking status of the cage.

Abstract: An animal isolation and caging system which maximizes cage density within a ventilated rack is provided. The rack includes at least one air exhaust plenum, and at least one canopy disposed within the rack for ventilation of the cages housed in a rack system. The rack is capable of supporting a first cage within the rack below a first canopy, and also positioning a second cage below a second canopy. The filter top of the first cage provided by the invention also provides a filter retainer having a filter top retainer wall designed to be in contact with a first canopy unit forming an enclosed space so configured as to create an enclosed space from which the animal isolation and caging system of the invention creates a zone of negative pressure so as to permit air to be drawn into an air exhaust plenum or duct from the interior of the first cage through the top of the first cage.

Abstract: A rodent cage including a cage bottom having a plurality of integral side walls, a floor and an open top end. A peripheral lip extends continuously around the top end. A pair of recesses are disposed on the peripheral lip. A feeder assembly has a frame and at least one section descending therefrom. The frame has pair of flanges extending therefrom so that when the feeder assembly is disposed in the cage bottom the pair of flanges are mated with the pair of recesses, respectively. A bonnet is dimensioned in size for sealing the top end of the cage bottom. A lock is disposed on the bonnet for preventing rodents housed in the cage from displacing the bonnet from the cage bottom.

Abstract: A work station having an environmental controller for maintaining air flow in and through the work station at a user-selected level. The work station includes a pressure cabinet and a perforated work surface forming the top of the pressure cabinet. A pressure inducing assembly is located within the cabinet below the work surface to draw air into the cabinet and create a negative pressure in a work space defined above the work surface. A support coupled to two sides of the pressure cabinet provides a channel for air flow from the pressure cabinet to an air chamber located above the work surface. Air is drawn from the air chamber generally downward toward the work surface by the negative pressure created in the work space to provide an air curtain substantially surrounding the work surface.

Abstract: A sound reducing system comprises a housing, acoustic baffle, and acoustic netting. The acoustic baffle is covered with a waterproof protective casing which protects the acoustic baffle from dirt and moisture without interfering with its acoustic properties, and allows it to be cleaned with fluids. The housing comprises an inner pan and an outer pan which are pivotally coupled. The acoustic baffle and the acoustic netting are disposed within the housing, but can be removed for cleaning when the housing is opened. When the acoustic baffle and acoustic netting members are placed back within the housing, they are protected from damage.

Abstract: A sipper tube cap assembly is provided having a cap with a flat surface and a curved wall. A circumferential flange is formed by the flat surface and further defines an opening in the cap. A stopper, having a hole formed therein, is positioned in said cap by said circumferential flange to retain the stopper within the cap. Finally, a sipper tube is provided which is positioned within the hole in the stopper, to extend through the opening.

Abstract: A rodent cage including a cage bottom having a plurality of integral side walls, a floor and an open top end. A peripheral lip extends continuously around the top end. A pair of recesses are disposed on the peripheral lip. A feeder assembly has a frame and at least one section descending therefrom. The frame has pair of flanges extending therefrom so that when the feeder assembly is disposed in the cage bottom the pair of flanges are mated with the pair of recesses, respectively. A bonnet is dimensioned in size for sealing the top end of the cage bottom. A lock is disposed on the bonnet for preventing rodents housed in the cage from displacing the bonnet from the cage bottom.
