Description
The Thermo Scientific Model 1335 is a 4-foot Class II, Type A2 biological safety cabinet designed to deliver exceptional contamination control, operator protection, and energy efficiency. Powered by advanced brushless DC motors, it reduces operational power consumption and HVAC loads by up to 75% compared to legacy AC-motor hoods. Featuring a seamless, single-piece stainless steel interior and a 10-degree sloped front window, the 1335 optimizes workspace ergonomics while simplifying decontamination routines for cell culture, clinical diagnostics, and microbiological research.
Features:
-
SmartFlow Airflow Design: Automatically balances and adjusts internal inflow and downflow velocities in real-time, maintaining an absolute containment barrier even as the HEPA filters load over time.
-
Digital Airflow Verification (DAVe): Onboard safety monitor provides clear real-time readouts and utilizes visual and audible alarms to alert users instantly if airflow drop thresholds are crossed.
-
Night Set-Back Mode: When the front glass sash is fully closed, the intelligent controller drops blower speeds to 30%, keeping the workspace sterile while minimizing energy consumption during off-hours.
-
SmartClean Window System: The front sash window easily lowers beyond standard working bounds to allow effortless, comprehensive wiping of the inner glass surfaces without disrupting containment safety.
-
SmartPort Passage: Two integrated 3-inch side wall routing ports provide clean, negative-pressure passage for vacuum lines, tubing, and power cables without cluttering the main sash opening.
-
Ergonomic Front Slope: A 10-degree inclined front viewing glass reduces arm, neck, and eye fatigue during long operational shifts.
