These microprocessor-controlled PCR workstations from AirClean Systems reduce risk of sample contamination during DNA/RNA amplification and manipulation. These PCR workstations are available in 24’’, 32’’, and 48’’ widths and include additional features like built-in 254 nm ultraviolet lights for irradiation and HEPA filtration for a clean work area. A UVTect Microprocessor Controller comes standard on 32" and 48" models and helps maintain airflow to provide a clean Class 100 work area during PCR preparation. The controller provides audible and visible alarms to alert the end user of insufficient airflow, UV bulb changes, and HEPA filter changes and also allows the operator to change blower speed and digitally set irradiation timer and lab event timer to current application requirements. Each workstation features an interlocking sash with a safety switch that automatically turns off the ultraviolet light and activates blower and fluorescent light when the sash is raised.
