All Purifier Series Cell Logic Biosafety Cabinets operate using the following
principles:
• Filtration and retention of particulates by High Efficiency Particulate
Air (HEPA) filter(s)
• Laminar airflow
• Directional airflow
The major components in a Biosafety Cabinet are:
• The HEPA filter(s) or optional ULPA filters
• The motor/blower to force air through the Cabinet
• Cabinet air intakes (grilles), ductwork and air balance controls
The two major package options of a Cell Logic Biosafety Cabinet are:
• The Scope-Ready™ package option to allow a user-supplied
microscope to be integrated into the cabinet.
• The Temp-Zone™ package option that includes a temperature
controlled work area when connected to a user-supplied circulator.
HEPA Filters
HEPA filters are disposable, dry-type particulate filters. The filter material or
media is typically made of borosilicate microfibers formed into a thin sheet,
in a process similar to the production of paper. This sheet is folded, or pleated
to increase its surface area. The pleats are held in place by aluminum
diffusers or by beads of glue that add rigidity to the media pack. The pack is
then set into a frame, and sealed as shown in Figure 4-1.
