PCRSafe™ Ductless Class II Recirculating Enclosure

PCRSafe™ Ductless Class II Recirculating Enclosure

Protection from hazardous samples



Developed for working with potentially hazardous samples during DNA amplification, the PCRSafe recirculating enclosure provides protection to both sample and operator. Airborne contaminants are captured in HEPA filtration before entering the active workspace. The exhaust air is HEPA filtered so harmful particulate is not released into the room.

PCRSafe is constructed of white polypropylene which does not allow for bacterial build-up and can easily be cleaned with any disinfectant product. To further reduce the threat of cross-contamination, the built-in timed UV light can be used to irradiate work surfaces and tools between samples or cases.

Full-closure sash and safety switch prevent operator exposure to UV energy. UVTect microprocessor controller constantly monitors filter conditions and alerts the user if filter replacement is needed.



  • UVTect™ microprocessor controller
  • Polypropylene construction for chemical resistance. The result: NO RUST
  • UV and fluorescent lights
  • Positive pressure HEPA filtered clean air
  • No ductwork required
  • No installation required - plugs directly into a standard 110V or 220V electrical outlet
  • Digital UV light timer :01-59 minutes
  • Lab event timer
  • Filter safety lockout to ensure correct filter replacement
  • Polycarbonate and polypropylene design reflects UV energy
  • Exhaust air is HEPA filtered, keeping any potential particulate from returning to the room
  • Filter and electronics are located above the workspace, eliminating the chance of a chemical spill entering these sensitive areas
  • Real time monitoring of installed filtration bed



PCRSafe™ Ductless Class II Recirculating Enclosure  Airflow Diagram

PCRSafe™ Ductless Class II Recirculating Enclosure Airflow

  1. A
    Room air enters and is pulled into the lower baffle along with a portion of the chamber air. Air travels through the lower baffle and up the rear baffle.
  2. B
    Chamber air is mixed with room air.
  3. C
    Contaminated air is directed through the filtration bed.
  4. D
    The majority of air moves through the HEPA filter which provides ISO 5 clean air to the chamber.
  5. E
    Remaining air is HEPA filtered and exits the enclosure.



  • ULPA filter
