  • Image format: 16-bit TIFF

  • Resolution: 600 dpi

Scan Gel

The scanner must be unlocked before scanning. See Initial Setup for instructions.

  1. Start D‑DiGit Image Acquisition Software.

  2. Click Image Capture D-DiGit software image capture on the Main Control Panel to image the gel.

    Tip: The default exposure time is 4x. For higher sensitivity, drag the slider bar to the right to increase the exposure time. Drag the slider bar to the left to decrease the exposure time and lower sensitivity.

After a scan is completed, the scanned image will be saved to the folder defined under Settings D-DiGit software image settings . For information about changing the folder location, see Software for the D‑DiGit Gel Scanner.

Excising or Observing a Gel

    After the Light button has been clicked, a countdown timer will appear in the software and will start counting down from 3 minutes. After 3 minutes, the blue LED will turn off and the software will prompt you to wait for 2 minutes before using the light again.

  5. Once you are finished, click Light Off to turn off the light and exit the countdown timer.
