  • Esco - Frontier Series

The Esco Frontier™ PVC Acid Digestion Fume Hood is designed for ensuring operator safety when performing acid digestion applications. This specialized fume hood is built with unplasticised polyvinylchloride (u-PVC) internal surfaces, including the work surface. The superior chemical resistance of the u-PVC interior liner enables it to withstand the use of very concentrated acids used in acid digestion applications*.  It is available also in Polypropylene (PP). The sash window is polycarbonate, not glass, since glass is easily etched by hydrofluoric acid, a common acid used. Esco includes many features in the design of cabinets such as this to provide optimal safety and user comfort.
 

Key Benefits:
 

  • High energy efficiency for substantial long-term savings
  • Full u-PVC (unplasticised polyvinylchloride) or Polypropylene for durability under harsh conditions
  • Excellent user protection against acids; superior containment at 0.3m/s
  • Designed for optimal user ergonomics including 5-degree sloped front
  • UL classified
     

* This fume hood is not meant for perchloric acid applications.

Disclaimer: Esco FrontierTM is UL classified.  Due to the custom nature of the range, some options do not qualify for the UL label.

 

Features
OPERATOR SAFETY
  • Tri-wall construction for maximum robustness.
  • U-PVC or PP internal chamber and exhaust collar ensures superior chemical resistance.
  • Shaping vanes increase airflow "sweep" at the critical sidewall area to improve containment.
  • When the sash is raised above 18 inches, it will automatically and gently fall back to the appropriate level, ensuring operator safety. This is due to Esco’s unique “Creep-down Mechanism”.
  • The sash can be locked by the laboratory manager or safety officer to restrict operations at sash openings above 457mm (18.0") or in the closed position in the event of an emergency or to restrict access.
  • Aerodynamic foil entry provides maximum airflow to "sweep" the critical boundary layer near the work surface level to reduce turbulence and eliminate backflow.
OPERATOR BENEFITS
  • Sash is made from polycarbonate to prevent hydrofluoric acid fume etching enhancing visibility.
  • U-PVC or PP internal work zone allows for easy cleaning of all surfaces and removable baffle system allows for thorough cleaning inside the hood.
  • System is designed for easy access plumbing, lighting and electrical components for ease of maintenance
  • Sloped front for user ergonomics and safety
