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.

CHANGING THE UV WAVELENGTH

A UV Crosslinker is purchased with shortwave, longwave or midrange tubes. However, if user
requirements and applications change, the Crosslinkers provide you with the unique ability to change
the ultraviolet wavelength and recalibrate the UV sensor and microprocessor to the new UV
wavelength. This is accomplished by purchasing FIVE tubes of the NEW UV wavelength and the proper
UVP calibration sensor.

TUBE P/N WAVELENGTH UVP CALIBRATION SENSOR P/N
34-0006-01 365 nm Longwave 97-0016-02 UVX-36 Longwave

34-0042-01 302 nm Midrange 97-0016-04 UVX-31 Midrange
34-0007-01 254 nm Shortwave 97-0016-01 UVX-25 Shortwave

UV Wavelength Calibratio n Pr oce dur e

1. After disconnecting the unit from the electrical supply, install the FIVE NEW WAVELENGTH
Tubes as directed. (Section - Changing tubes).

2. Plug the corresponding UV calibration sensor into the TOP HOLE just inside of the door at the
upper right.

3. Place the UV calibration sensor in the middle of the floor of the exposure chamber.

4. Close the Crosslinker door.

5. Invoke the calibration mode of the Crosslinker by pushing/holding down STOP on the tactile touch
pad and turning the power to the unit ON.

6. A sequence of tones will be heard from the Crosslinker and a 180-second count will display on
the LCD when the calibration procedure has started.

7. No calibration occurs during this 180-second period. This period allows a UV tube warm-up and
stabilization period.

8. Upon completion of the 180-second period, measurements are automatically made with the UV
calibration sensor and the Crosslinker sensor. These measurements are compared to limits of
acceptability and/or if sensor operation is within range.

9. If sensor readings are unacceptable, an error code (01, 02, 03 or 04) will flash on the LCD Press
any key to stop.

10. Check all connections and redo calibration. If the same error message appears, call UVP.

11. The previous calibrated operation of the Crosslinker will continue following any unsuccessful
recalibration. Replace the new UV wavelength tubes with the previously removed old wavelength
tubes.

12. Successful recalibration to the NEW UV wavelength changes the values in the microprocessor
and numeric setting value is displayed on the LCD. To return to original or another wavelength
the proper UV calibration sensor is needed.

CROSSLINKER CALIBRATION PROCEDURE

Equipment necessary:

• Chart recorder

• Two probes with banana plug adapters

• One radiometer with UVX-25 calibrated sensor

• Cable with banana plug and jack adaptor to connect radiometer to chart-recorder

• Power source (100V, 115V or 230V)

Procedure:

1. Connect the Crosslinker to the power source. Do not turn on the unit at this time.

2. Connect the testing probes to the chart recorder and to the Crosslinkers PCB as follows:

PEN 1 (red) to the right side of R7
PEN 2 (blue) to the right side of R6
Ground both pens at the lower part of R2
Note: While connecting these probes, the switches for both pens on the chart recorder should be

on ZERO position to avoid possible damage to the recorder.

3. Place the UVX-25 sensor inside the Crosslinker at the center and slide the sensor cable through
the upper hole of the inner chassis. Plug the sensor cable into the PCB's jack.

4. Select 5V scale for both pens. Turn the chart recorder on.

5. Select a speed of 15mm/min.

6. Switch both pens to MEASURE and DOWN positions so they can touch the chart paper.

7. Adjust the ZERO position for both pens.

8. Press the CHART DRIVE switch.

9. Run the Crosslinker in calibration mode by depressing the STOP/RESET button and turning the
power switch on at the same time. At this point, both pens should start recording information on
paper. Sometimes either pen will record zero information regardless of the lights in the
Crosslinker being on, if this is the case, check for bad connections.

10. During calibration, check the voltage levels on both pens. By adjusting the potentiometers R21
and R29 on the PCB, adjust the values of R6 and R7. Depending on the voltage used, from past
units it has been found that the optimum values for these levels are:

VOLTAGE RANGE FOR R6 RANGE FOR R7
115V 3.3-3.5V 2.1-2.3V
220V 3.5-3.7V 1.7-2.0V
100V 2.5-2.7V 2.6-2.9V

11. When the calibration cycle is finished, move both pens to UP and ZERO positions.

12. Unplug the UVX-25 sensor and disconnect the probe for PEN 2.

13. At this point, it is necessary to check the energy levels of the Crosslinker to see if the unit was
calibrated properly. Slide the UVX-25's cable through the lower hole of the inner chassis and plug
it into the radiometer.

9

UV CROSSLINKERS UVP

14. Set the radiometer scale to 20mW/cm

2

.

15. Connect the radiometer to PEN 2 of the chart recorder.

16. Select 1V scale for PEN 2 and a speed of 60mm/min.

17. Lower both pens, turn the CHART DRIVE switch on, change the pens' switches to MEASURE
position and adjust for zero level.

18. Select an energy level of 600 Joules on the Crosslinker and press the START button.

19. When the cycle is completed, repeat for 1,200 and 2,000 Joules levels.

20. Obtain the actual amount of energy in Joule/m

2

by calculating the area encompassed by the
recorded data curve and zero baseline times 100. Compare it with the energy selected. They
should be within a range of +/- 10%. If this is not the case, adjustments of potentiometers R21
and R29 should be made during a repeat calibration. Repeat all the above procedures until the
actual levels are within range.

21. When the three levels of energy are acceptable, disconnect the sensor and the chart recorder
from the Crosslinker. At this point, the unit is ready to be tested.
