Turn the key to the off position after UV irradiation to prevent exposure of samples to the UV. Ensure
the key is completely inserted into the lock.
[Note] A safety switch sensor is built into the bottom of the door. When the door is opened, the
ultraviolet lights will automatically shut off.
[Note] Do not attempt to perform PCR procedures with the germicidal lamp on. The germicidal lamp is
used to decontaminate the internal chamber of the between experiments.
[Warning] Exposure to UV light is harmful.
The Makrolon
® door is UV blocking and will not allow UV radiation to pass through the door. The
germicidal tubes will shut off if the panel door is opened. The PCR Workstation contains a powerful
source of UV radiation that will cause damage to unprotected eyes and skin. Before operating any unit,
be sure all personnel in the area are properly protected. Even though the unit shuts the UV off when the
door is open, UV Blocking Eyewear should be worn as well. UVP has a complete line of UV Blocking
Eyewear: Spectacles, Goggles and Faceshield designed for this purpose.
Extended periods of time UV exposure can be used to disinfect the interior chamber by the destruction
of organisms. Refer to the Maintenance section for information on measuring the intensity of the UV
tubes with a UV meter.
Overhead White Light
The overhead white lights can remain lit at any time throughout experiment procedures or the
decontamination process. The fluorescent white light provides a bright light within the PCR Workstation.
To use the white light, press the ON button located on the top panel.
Care and Cleaning
The units are built to provide trouble-free operation.
NOTE: The door and side panels are made of Makrolon ® and are subject to scuffing and scratches if
improperly cleaned. If crazing of the Makrolon
®
panel occurs, the panel can be replaced. Refer to
Replacement Parts for part numbers.
The stainless steel and aluminum surfaces are manufactured with an antimicrobial coating to reduce

sponge.
•
Use mild soap and a damp soft cloth or damp sponge to clean the exterior of the unit.
