Introduction

This single chamber unit is designed for the variable-temperature inc ubation and humidification
envelopment of microbiology organisms, biology assays and any protocol requiring heat incubation
in the range of ambient +10°C to 68°C.

The Incubator is constructed with built-in overhead shortwave 254nm UV tubes for decontamination
of the chamber between experiments.

Safety Information

The UV Incubator is designed with function, reliability and safety in mind. It is the user’s
responsibility to install the unit in conformance with local electrical codes.

Indoor Use

Installing the Incubator

1. Remove the incubator from its packaging.

2. Place the unit on a level working surface and provide adequate room in front of the system to allow
the door to be opened easily.

3. Plug the female end of the power cord into the back of the unit.

4. Plug the male end of power cord into a surge-protected electrical outlet.

5. Press the I/0 toggle switch located in front of unit to turn the incub ator on. The touch pad should
illuminate.

6. Select the desired temperature by pressing the touchpad up and down arrows. The internal
temperature will be displayed on the touchpad.

Operating the Incubator

Setting the Temperature

When the power is turned on, the LED display flashes the software version number for several
seconds. The display will then show the internal ambient temperature for several seconds and
adjust to the set temperature (displayed in degrees Celsius). This setting is adjustable from the
ambient temperature to 68

The current setpoint value can be altered by pressing the “UP” and “DOWN” buttons on the
touchpad while the value is being displayed on the LED display. To change the setpoint:

1. Momentarily press then release either the “UP” or the “DOWN” button. The LED intensity will

flash to indicate that the displayed value is the current setpoint.

2. Increase or decrease the setpoint value by pressing the “UP” or “DOWN” buttons respectively.

If either button is held down for more than several seconds, setpoint value will increase or
decrease continuously.

3. When the desired setpoint is reached, wait approximately five seconds without pressing either

button. The display will revert to normal mode showing the actual temperature.

The new setpoint becomes effective and is stored in the non-volatile memory when the display
reverts to the normal mode.

Calibrating the Temperature Reading

The incubator is calibrated at the UVP factory at 37 oC. UVP recommends that temperature
recalibration be performed at the UVP factory as recalibration by the user may void the warranty.
Obtain an RGA (Returned Goods Authorization) number from UVP prior to returning a unit to the
factory. Call UVP’s customer service department for information.

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

UV key in the OFF 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 -Asperg ill us nig er

-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.

Care and Cleaning

The units are built to provide trouble-free oper atio n.

NOTE: The door is made of a polycarbonate plastic material and is subject to scuffing and
scratches if improperly cleaned.

sponge.

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

• Use a mild detergent on the interior surfaces.

• Warning: Unplug the UV incubator before cleaning around the UV bulb contacts.

• Clean the door with a mild detergent; never use organic based compounds or cleansers

containing alcohol or ammonia.

• Do not use abrasive pads or cleansers.

• A plastic cleaner solution is recommended to clean the door. Such cleaner is available

from local plastic supply distributors.
