The Sentinel Gold microprocessor controller displays all safety information on one screen. It is centered and angled down for easy reach and viewing, and has a selectable Quickstart mode for fast operation.

The DC ECM motor provides 70% energy savings compared to AC motor; stable airflow, despite building voltage fluctuations & filter loading; and Night Setback mode to further reduce power consumption by 60%.

ULPA filters have 10x filtration efficiency of HEPA filters and creates an ISO Class 3 work zone instead of the industry-standard ISO Class 5. HEPA filters only offer 99.99% typical efficiency at 0.3 micron, while ULPA filters provide 99.999% typical efficiency for particle sizes of 0.1 to 0.3 micron.

The ISOCIDE powder coat is silver-ion impregnated which inhibits microbial growth to improve safety.

The design of the Esco Labculture biosafety cabinet was optimized to give large performance envelope, that provides operator and product protection at wide inflow and downflow variation from the nominal point.

Ambient air is pulled through the front grill to create inflow, without going into the work surface. Inflow is joined by half of the downflow, to create front air curtain that is fine-tuned to create a large performance envelope. The combined air stream travels through the back air column towards the blower.

Approximately ⅓ of the air in the common plenum is exhausted through the ULPA filter to the room. The remaining ⅔ of the air is passed through the downflow ULPA filter and into the work area as a vertical laminar flow air to create ISO Class 3 work surface and prevents cross contamination.

Near the work surface, the downflow splits. About half goes to the front grill, and half goes to the rear grill. A small portion enters the side capture zones to prevent dead air corners.

Our technicians test each bio safety cabinet to ensure that the controls and blower motor work properly. Unless otherwise specified all bio safety cabinets come with new HEPA filters installed by our technicians at our facility prior to shipment. Our testing procedure includes all the elements of a bio safety cabinet certification in order to ensure that the unit will pass certification once it is at your site.
