•               Ensure easy visibility of the animals
•               Provide for safe handling and provide for ergonomic considerations
•               Provide adequate filtration to ensure biosecurity requirements are met and to decrease staff’s exposure to animal allergens
•               Must  be  compatible  with  existing  infrastructure  (cage  wash  robotics  system,  logistics distribution equipment)
                                                                                           
FUNCTIONALITY:
The equipment must conform to the following specifications:
Single Side Rack:

• Minimum floor space specifications;
• Cage body must have no need for latches to achieve high level of sealing.
• Must include quantity of 28 cages.
• Acceptable  plastics  for  cage  bottom  and  top:  Clear  Polysulfone,  Polysulfone,  and  Polyphenylsulfone. Materials must be resistant to detergents used repeatedly for cleaning and sanitization.Materials must also be autoclavable (shape and transparency of plastic must be maintained).
• Water  bottles  must  be  manufactured  with  thermoplastic  materials  (ex:  polysulfone)  or  equivalent. Materials must be resistant to detergents used repeatedly for cleaning and sanitization.Materials must also be autoclavable (shape and transparency of plastic must be maintained).
• Bottles must be compatible with current water bottle processing equipment, including sizing for basket placement and water filling. To be compatible, bottle dimensions must be harmonized to fit the lid.

• Water bottles must include reliable silicone seals with the bottle cap, preventing any leakage resulting in wet cages and must be compatible with the bottle automation system from IWT.
• Water bottles must be able to hold a minimum 340 ml of water.
• Must have half wire bar lid for easy access to the animal. The lid must be made of high quality stainless steel, in order to avoid rust and oxidization that can affect the animal health, without any dangerous point (sharp edges, v‐shaped points).
• Cage top must feature an external self‐centering depression for water bottle: in this way the operator does not need to center the hole with the bottle cap, but the bottle slides in by itself. No need to pull out the cages from the rack to perform the bottle change.
• All  cages  must  be  fitted  with  a  microbiological  filter  in  order  (0.2um)  to  provide  safety  for  both operators and animals.
• The inlet and outlet air nozzle must be configured to avoid cross‐contamination. Air valves must be self‐closing and well‐sealed in order to have high level of sealing when the cage is undocked from the rack.
• Inlet and outlet air nozzle at the rear top of the cage preventing the animals from being exposed to air drafts and consequently from potential anxious behavior and stress.
• Cages must be made to provide micro‐isolation conditions in either positive or negative pressure.  Cages must also be able to maintain a secure environment in the event of a power failure.

• The cage shape and the absence of a wire-bar lid allows perfect visibility into the cage for animal examination on both floors. The hatch, which is optional, also allows the handler to reach into the cage without removal from the rack. When the cage is used under negative pressure the hatch allows the animals to detect familiar handlers and reduces startling of the animals.

The plastic runners are snapped on to the tubular rack frame with no screws needed, thus reducing the total weight of the rack and keeping it neat and clean with no parts protruding. Heavy duty, fully autoclavable fiber glass reinforced nylon castors - maintenance-free, two with brakes and two without for optimal guidance.
• The rack runners have built-in stoppers that fit the stopping lugs precisely, so each cage stops and locks silently into place automatically. A visual indicator flags any cage that is not fully docked without needed of further operation from the operators.
