The Pass-Through Cabinet is constructed within accordance for this type of equipment as defined in the U.S. Centers for Disease Control/National Institutes of Health publication Biosafety in Microbiological and Biomedical Laboratories, 5th edition (BMBL).
The pass-through atmosphere is maintained at a negative operating static pressure typically between -0.5” WG - 1.5” WG with an inlet air velocity into the open port of 125 +/- 25 linear ft/min with 10 atmosphere changes per hour that is a once-through airflow system.
The air supply system for the pass through is a ducted inlet with HEPA filter (active supply).
The pass-through may be mounted on a stand or a working surface with the working viewing angle of 10%.
- Constructed of 316L stainless steel material with a #4 finish.
- Rounded corners with a minimum 15.875 mm (5/8”) inside radius to allow easy cleaning and decontamination.
- The inside of the cabinet bottom is flat.
- Air monitoring ports.
- Decontamination ports.
- HEPA filter aerosol challenge ports.
- Filter system will be mounted on top of the cabinet.
- Both return and inlet is filtered. Filters are of a CERTEK design and supplied by CERTEK. Inlet and outlet will have dampening valves.
- Neoprene gaskets in the 35 to 45-durometer hardness range.
- Internal opening door on each side and one in the rear with cam lock closures only accessible from the inside.
- Front viewing window in the external front door with a 10% angle. The window will be constructed of 9.525 mm (3/8”) thick polycarbonate with a chemical resistance coating.
- One (1) 815 mm (32”) glove port with the glove constructed of Butyl or Hypalon material with a stainless steel entry port is optional (for an additional charge).
- No electrical port (receptacle outlet) will be provided.
- Externally mounted LED electrical lighting will be mounted at the top of the glass along the length of the front viewing area of the door for ease of maintenance.
