KODAK Gel Logic 2200 Imaging System Features  
     
  Cooled CCD Camera

CCD Sensor
  • GL 2200 Camera Assembly contains the CCD camera and lensing system. This assembly is designed as a single serviceable unit
  • The Gel Logic 2200 Camera is cooled to -29 ºC to allow for the sensitive imaging of low light signals, such as chemiluminescence and faint fluorescence
  • A 6x zoom lens allows continuous adjustment of the field of view from 4.7 cm x 3.5 cm to 28 cm x 21 cm (28 microns/pixel at full zoom)
  Integrated UV and White Light Illumination

The GL Integrated Illumination Cabinet integrates both transillumination and epi-illumination for both UV and white light excitation allowing you to image a wide variety of fluorescent and colorimetric samples. The cabinet provides a light-tight environment for chemiluminescent imaging and is equipped with built-in white light epi-illumination for imaging opaque samples like plates and colorimetric blots.


  1. The Gel Logic 2200 Camera Assembly contains the cooled CCD camera and is mounted to the top of the cabinet. The pixel resolution is 1708 x 1280 pixels.
  2. The Filter Slider facilitates the use of filters. The Active Location Indicator Slot designates the position that is under the lens. Two additional slots are provided for convenient storage of filters not in use. Both a 590 nm and a 535 nm filter are included in the package. These filters are especially designed to eliminate light other than 590 nm or 535 nm wavelength produced by ethidium bromide or SYBR Green (or other similar emission wavelengths), respectively. Additional filters, including 440 nm, 570 nm, 670 nm and custom filters are also available.
  3. The Illumination Selector turns the illumination sources ON and OFF. An indicator light is displayed when the light is ON.
  4. The Imaging Cabinet Door permits access to the area under the camera, which accommodates the imaging of samples from 4.7 cm x 3.5 cm to 21 cm x 28 cm.
  5. The UV Transilluminator provides a uniform intense (306 nm peak emission) source of ultraviolet radiation. The sample work area is 35 cm x 47 cm, however the UV imaging area is limited to 21 cm x 28 cm.
  6. The UV Switch turns the UV Transilluminator ON only when the UV Safety Shield is in place and the Illumination dial is turned to the TRANS UV position.
  7. The Timer Dial activates the automatic UV light shutoff. When the UV timer switch is ON, the UV Transilluminator lamp within the GL Integrated Illumination Cabinet automatically turn OFF after 15 minutes.
  8. The Epi-illumination Light Module is easily mounted on the inside of cabinet door. The system includes a 370 nm module. Optional accessories include 254 nm and 306 nm wavelength modules.
  Acquiring Images

The GL 2200 supports a wide variety of image capture methods including single capture exposure, multiple capture exposure (accumulated into a single file or as separate files), time lapse exposures, and progressive exposures. Using these exposure modes, the minimum and maximum exposure times are 0.05 second and 100 minutes, respectively.



The GL 2200 Acquire window is accessed from within KODAK MI. Choose Select Digital Camera from the KODAK MI File menu and GL 2200 from the Digital Camera pop-up menu. After launching GL 2200, the GL 2200 Acquire window appears.

  1. The User section contains options to select a predefined setting, record your name, and add annotations on the image for printing.
  2. The Exposure section provides you with the various exposure methods and options associated with capturing images.
  3. The Illumination section designates the type of illumination used to capture your image and applies the appropriate illumination reference file, when necessary.
  4. The Set Camera section records the position of the camera lens f-stop and field of view. In addition, it provides a pop-up menu for recording the filter used during capture. These parameters are important for documentation and calibration of your image.
  5. The Buttons section contains the Preview, Expose, Preferences, and Done buttons used to navigate through an image capture.
