Esco Frontier PVC Acid Digestion Fume Hood is designed to be used when performing acid digestion applications. This fume hood is not meant for perchloric acid applications.

This specialized fume hood is built with unplasticised polyvinylchloride (u-PVC) internal surfaces (including the work surface) and a polycarbonate sash window. Acid digestion applications use very concentrated acids. Therefore u-PVC interior liner is utilized due to its superior chemical resistance. Polycarbonate sash is used as glass is easily etched by hydrofluoric acid, a common acid used in such applications.

Features

Superstructure
•Tri-wall construction for maximum robustness.
•U-PVC internal chamber constructed of unplasticised polyvinylchloride.
•Chain and Sprocket Sash support system.
•Hood lighting is pre-wired. Lighting is electronically ballasted, energy efficient, instant start. Typical light intensity on work surface is >1076 lux in zero ambient conditions.
•U-PVC exhaust collar ensures superior chemical resistance. Safety Features

•Shaping vanes increase airflow "sweep" at the critical area at the sidewall to improve containment, especially when laboratory personnel walk fast in front of the hood.
•Sash is made from polycarbonate to prevent hydrofluoric acid fume etching.
•Sash stop limits sash movement beyond 457mm (18.0"), 'encouraging' user to work at safe positions.
•When sash is raised above 457mm (18.0"), it will automatically and gently fall back to the safe level (Esco’s creep-down mechanism) unless held in place. This allows the sash to be raised temporarily to the full open position for set up of equipment and apparatus in hood, while enforcing regular operation of the hood with lowered sash.
•The sash creep-down mechanism can only be disabled with a key. This permits the laboratory manager or safety officer to restrict operations at sash openings above 457 mm (18.0").
•Sash key lock allows laboratory manager to restrict access to the fume hood.
•The sash can also be locked down in the fully closed position with the key , in the event of a fume hood fault, facility shutdown, or, simply to restrict access to equipment set up in the hood.
•Hot zone baffle system rapidly draws contaminants out of the fume hood work zone in a single pass displacement of air. With this feature, Thermal Heat Relief is quickly achieved.
•Aerodynamic foil entry provides maximum airflow to "sweep" the critical boundary layer near the work surface level to reduce turbulence and eliminate backflow.
•Ergonomic sash handle gently directs air into the hood without sacrificing visibility. Serviceability

•U-PVC internal work zone allows for easy cleaning of all surfaces.
•Removable baffle system allows for thorough cleaning inside the hood.
•Chain and sprocket system requires minimal service.
•Internal access panels on side walls facilitate access to plumbing connections for service especially when hoods are installed next to each other.
•Removable front panel facilitates easy access to lighting and other electrical components mounted above the hood chamber. Safety Certified and Tested
All Esco fume hoods are manufactured for the most demanding laboratory applications.

•Each Frontier Acid Digestion Fume Hood is tested to comply with ASHRAE 110:1995 and EN14175-3 standards.
•Sash is clearly labeled with all operating instructions and illustrations.
