Imager- Molecular : Chemidoc Hood, On/Off , UV Shield
STLCC_CPLS;Morrison 9/28/2012 Page 2
Power lines for the Camera
and Imager controls have
been routed to the Power
strip located right in front
of the unit.
Flip the Power Strip to “ON”
to Turn on both of these
units
How to install UV Shield when necessary
Pull out drawer, insert in slot at top .
1. Membrane buttons and
LEDs for hood.
2. Normally these are NOT
USED as the ImageLab
software will control all
functions for setup, image
capture, and analysis
Filter Choice Lever:
None, Filter 1, Filter 2
USB line to PC MUST
be connected to the
port as labeled on the
PC case.
Imager- Molecular : XcitaBlue and White Light Conversion

Conversion screen for viewing SYBR Green, SYBR Safe,
and other fluorescent gel stains, includes viewing
goggles, SYBR Safe filter; for use with Molecular
Imager® ChemiDoc™ XRS+ and Gel Doc™ XR+
systems
Note: Be sure to run calibration at Edit-Setup with these options once to correct focus and flat field lens operations

Imager- Molecular : ChemiDoc XRS Features
STLCC_CPLS;Morrison 9/28/2012 Page 4
The Molecular Imager® ChemiDoc™ XRS+ system is based on CCD high-resolution, high-sensitivity detection technology and
modular options to accommodate a wide range of samples and support multiple detection methods including fluorescence,
colorimetry, densitometry, chemiluminescence, and chemifluorescence. The system is controlled by Image Lab™ software to
optimize imager performance for fast, integrated, and automated image capture and analysis of various samples.
The system accommodates a wide array of samples, from large handcast polyacrylamide gels to small ReadyAgarose™ gels and
various blots. The system is an ideal accompaniment to PCR, purification, and electrophoresis systems, enabling image analysis and
documentation of restriction digests, amplified nucleic acids, genetic fingerprinting, RFLPs, and protein purification and
characterization.
Key benefits include:
• Gel and blot imaging and analysis are quick and accurate
• Automated, hands-off routines; no training is required
• Save and recall all the steps in the workflow for repeatable and reproducible results
• Optimize the system at setup for image data that is always accurate, reproducible, and free of imaging artifacts
• Range of applications with special accessories to preserve sample integrity for downstream research while ensuring user safety
Comprehensive, automated quantitative analysis of protein and DNA samples in seconds
Customize and organize data in reports
Obtain publication-quality results quickly
