UV CROSSLINKERS UVP
INTRODUCTION
UVP Crosslinkers offer researchers an instrument to quickly, safely and efficiently expose samples to a controlled amount of ultraviolet radiation. CL-1000 series features a lay-down type drawer w hile the CX­2000 has a pull out drawer. Exposure of samples to UV provides for the following:
Crosslinking of DNA or RNA to nitrocellulose, nylon or reinforced nitrocellulose.
PCR sample contamination control.
Photoniking of DNA
Testing RecA function
Rapid site mapping
UV sterilization and sanitization
UV curing
The Crosslinkers are designed to measure and control the ultraviolet (UV) radiation within the exposure chamber. A unique UV sensor continually measures the UV energy and automatically adjusts to variations in UV intensity that occurs as the UV tubes age. This same UV sensor feedback measurement system allows you to set UV sample exposure, which automatically deactivates the UV sources when the set UV energy dose has been achieved.

IMPORTANT SAFETY INFORMATION

Ultraviolet Crosslinkers are a powerful source of ultraviolet radiation. Even though they are not easily accessible, do not attempt to disengage or override the internal safety interlocks. Exposure to the UV radiation may result. If the UV sources remain on when the door is open, the unit is malfunctioning and use should be discontinued until the unit is serviced. Do not expose unprotected eyes or skin to UV radiation. Always disconnect the UV Crosslinker from its electrical supply before servicing.

OPERATION
Place the Crosslinker on a level work surface. Be sure there is enough room in front to open the door. Plug the female end of the power cord into the Crosslinker.
Plug the male end of the power cord into a properly grounded electrical outlet. The proper operating
voltage of the Crosslinker is found on the product information label. Note: For 230V models, or those requiring special power cord connectors, ensure that the proper configuration of the male connector or the plug has been has been properly connected to the power cord.
Turn the On/Off switch to the ON position. Note: WHEN TURNED ON, THE CROSSLINKER
DEFAULTS TO THE LAST USED UV EXPOSURE SETTING.
The last UV exposure setting will now be displayed on the LCD. The last function setting will be noted
by glowing red spot(s) on the display panel.
Two operational Crosslinker settings are available: Preset UV Energy Exposure and Preset UV Time
Exposure. Preset UV Energy Exposure will provide a measured dose of UV exposure to the sample, whereas Preset UV Time Exposure only measures exposure time without regard to exposure intensity; therefore, when the unit is used in the Preset UV Time Exposure mode, there is no sensor involvement and thus there is no stated intensity value being delivered to the sample.

UV CROSSLINKERS UVP
The UV Crosslinker can be operated on the following settings:
A. Preset UV Energy Exposure Setting:
Push the PRESET and then ENERGY on the tactile touch pad. The red light at each
position should now be lit and the preprogrammed UV exposure setting of 120,000 microjoules per cm² is displayed in the LCD as 1200. Note: THE LCD DISPLAYS 1200. THIS MUST BE MULTIPLIED BY 100 TO OBTAIN EXPOSURE.
Push START. After a slight delay to energize the UV tubes, the LCD wi ll begin to count
down. The unit automatically stops at the end of the exposure cycle and will beep FIVE times. Exposure is now complete.
Note: Though the PRESET UV EXPOSURE SETTING is factory set at 120,000
microjoules per c m², it i s pos sible to change this if necessary, as follows:
Push and hold the PRESET on the tactile touch pad until you hear an audible signal then
push ENERGY also on the touch pad. Set your new PRESET UV exposure by pushing the numbers on the touch pad. Note: THE LCD DISPLAY MUST BE MULTIPLIED BY 100 TO OBTAIN THE PROPER
EXPOSURE SETTING. The new setting will appear on the LCD display. Push ENTER on the touch pad. The new
setting is now installed.
B. Preset UV Time Exposure Setting:
NOTE: For best exposure performance, turn the system on and allow 1-2 minutes for the
UV tubes to warm up immediately prior to exposing the sample.
Note: UV tube output intensity decreases with use over time. This change is not accounted
for in UV Time exposure applications. Push PRESET and then TIME on the tactile touch pad. The red light at each position should
now be lit and the preprogrammed UV exposure time of 2 minutes should be displayed in
the LCD. Push START on the touch pad. After a slight delay to energiz e the UV tubes, the LCD will
begin to count down. Note: THE TIME EXPOSURE IS SET IN MINUTES AND TENTHS
OF A MINUTE. The unit will automatically stop at the end of the exposure cycle and will beep FIVE times.
Exposure is now complete
.
Note: Though the PRESET ULTRAVIOLET TIME EXPOSURE is factory set to 2
minutes, it is possible to change this if necessary, as follows: Push and hold the PRESET on the touch pad until you hear an audible signal, then push
TIME.
Set your new PRESET UV TIME EXPOSURE by pushing the numbers on the tactile touch
pad. The new setting will appear on the LCD display. Push ENTER and the new setting will
be installed.
