OVERVIEW The AC600 Series LFUVC Model Workstation, with UVTect™ microprocessor-driven control, allows the operator to maintain a Class 100 clean work area during PCR preparation (nucleic acid preparation) and amplification. Airborne contaminants are eliminated through pre-filter and HEPA filtration. Class 100, vertical laminar airflow bathes the work surface and provides positive pressure at the face of the unit. The positive pressure eliminates potential airborne contaminants that may enter the workstation during amplification. UVTect™ provides variable speed blower control allowing the operator to increase or decrease airflow relevant to the application requirements. UVTect™ also provides constant monitoring of the filter, with audible/visual alarms to alert the user of a blocked filter. The LFUVC model also provides 254 nm short-wave UV light to effectively destroy contaminating DNA and RNA within minutes. Short-wave UV bulbs (254 nm) have a definable useful life of 1000 hours in the AirClean® Systems PCR workstation. The UVTect™ Controller tracks UV bulb hours and alerts the user when to replace the UV bulb. The AirClean™ Systems PCR Combination Workstation with UVTect™ controller ensures unmatched process protection and prevents operator exposure to short-wave UV energy.

WARNING: THIS WORKSTATION IS NOT DESIGNED FOR USE WITH BIOLOGICAL SAMPLES. AIRFLOW PATTERN 1) Room air enters at “A”. 2) Air is forced through pre-filter and HEPA filter creating laminar flow. 3) Clean laminar flow air enters work area at “B” and exits at “C”.
