If the user wishes to change the Spectrolinker to a different wavelength (i.e., 312nm or 365nm), the unit should be sent back to Spectronics Corporation for recalibration. The Spectrolinker chamber door is made of a special, transparent UV- blocking material so that the user can safely observe the operation.
SPECIFICATIONS Select XLE-1000 XL-1000 XL-1500 UV Tubes (5) 8-watt 254nm (5) 8-watt 254nm (6) 15-watt 254nm OverallHousing Dimensions— 19 x 10.25 x 9 in 19.5 x 10.5 x 9 in 24 x 10.5 x 14 in W x H x D (48.3 x 26 x 22.9 cm) (49.5 x 26.7 x 22.9 cm) (61.0 x 26.7 x 35.6 cm)
USEFUL CONVERSIONS Energy per unit area ( J/cm ) = Intensity ( W/cm ) x Time (seconds) μ μ 1mJ (millijoule) = 1000 J (microjoules) μ OPERATING MODES The user can operate the Spectrolinker in any of the four modes mentioned in this section.

The desired dosage should be entered on the number pad after pressing the ‘‘ENERGY’’ pad. Press ‘‘START’’ to begin operation. After the dosage is delivered, the Spectrolinker beeps four times and the display flashes ‘‘END.’’ Open the door at this point, and the display will oscillate between ‘‘DOOR’’...

4. Time Mode — When this mode is selected, the SECONDS LED lights to indicate that the value displayed or to be entered represents seconds. Enter the exposure time desired to a maximum of 9,999 seconds (2 hours, 46 minutes and 39 seconds). The minimum value that can be entered is one second.
TESTING AND SCREENING RecA The Spectrolinker can be used for testing and screening RecA mutation which can prevent repair of UV-induced damage on cells, thereby retarding their growth [6]. UV STERILIZATION When the Spectrolinker is equipped with short wave (254nm) tubes, various sterilization processes can be undertaken for laboratory purposes [7,8,9].
However, should problems eventually develop with regard to intensity measurements (as may occur with all light meters), the unit should be returned to Spectronics Corporation for recalibration. Be sure to contact the Customer Service Department at Spectronics for shipping instructions.
Corporation. In the U.S. and Canada, call toll-free 1-800-274-8888. Give full details of the difficulty and include the model and serial numbers of the unit and the date of purchase. Spectronics will make available, on request, circuit diagrams and component parts lists for any model unit.
If return of the Spectrolinker to the factory is deemed necessary, shipping instructions will be provided. If an estimate of charges for nonwarranty work or other service work is required, a quote will be furnished upon evaluation of the unit. Out-of-warranty service work will not be performed without customer approval.
