Setting the Decontamination Cycle
The SI-950 UV Incubator provides an automated process for eliminating contamination by utilizing
the germicidal properties of ultraviolet light. The UV light is typically operated when no samples are
inside the chamber. The entire chamber is decontaminated, eliminating viable fungi, bacteria and
yeast. Visible light decontamination makes the SI-950 ideal for cGMP sterility testing and BL3
laboratories.
To operate the decontamination function, turn the master power on. Then, turn the UV key lock to
the horizontal position to operate the germicidal lamp housed within the chamber.
Note: Do not attempt to incubate cultures with the germicidal lamp on. The germicidal lamp is used
to decontaminate the internal chamber of the incubator between experiments.
Insert the UV key to operate the
shortwave UV. Remove the key
after using the UV to avoid
accidental exposure of samples
during incubation.
UV key in the OFF position. UV key in the ON position.
Warning: Exposure to UV light is dangerous. Keep the door closed.
The incubator door is UV blocking and will not allow UV radiation to pass through. The germicidal
lamp will shut off if the door is opened.
A Word of Caution: The UV Incubator contains a powerful source of UV radiation that will cause
damage to unprotected eyes and skin. Before operating the unit, be sure all personnel in the area
are properly protected. It is preferable that the unit be installed and operated in an area where
access and exposure are limited while the unit is in operation. Even though the unit shuts the UV
off when the door is open, UV Blocking Eyewear should be worn. UVP carries a complete line of
UV Blocking Eyewear, including Spectacles, Goggles and Faceshield. See “Replacement Parts” for
more information.
Extended periods of time can be used to decontaminate the interior of the incubator chamber by
the destruction of organisms such as:
-Bacillus anthracis -Proteus vulgaris
-Bacillus subtilus -Salmonella
-Corynebacterium -Streptococcus hemolyticus
-Escherichlia Coli -Aspergillus niger
-Micrococcus candidus -Saccharoyces ellipoideus
-Mycobacterium tuberculosis -Influenza
-Chlorella vulgaris -And others
Recommendations for UV Decontamination
Typically, the germicidal lamp is used during periods of non-use (overnight and during weekend
periods of non-cultivation) to ensure a clean, non-infectious incubatory surface exists prior to
sample testing.
