• Allows to visualize chemiluminscent reactions

How is this unit better than Alpha Imager 3400:

For low-light applications, such as chemiluminescence, a longer exposure time may be appropriate and it is best to go to the red ACQUIRE IMAGE button to directly acquire the image once the desired exposure time is set. Alternatively, if a good exposure time is unknown, try selecting Auto-Expose and using the super sensitivity selection. Auto-Expose will generate an image showing the signal intensity usually in less than 3 minutes. Afterwards, a different sensitivity (binning) mode can be selected to generate a better resolution image and the software will automatically calculate the new exposure time for you.
