Calibrated Densitometer

  Calibrated Densitometer

The GS-800 calibrated densitometer delivers automatic calibration for superior accuracy, resolution, and image quality. With a 30 x 40 cm (11 x 16») imaging platen, 12-bit data ‎collection, and resolution down to 36.3 µm, the GS-800 is the perfect densitometer for all your protein and nucleic acid applications. Features of the system include:

  • Automated self-calibration for accurate quantitation
  • Variable scanning resolution for optimum image acquisition
  • 12-bit (4,096 gray levels) data col collection for greater linearity and sensitivity
  • Dynamic range from 0 to 3.0 OD
  • Scanning white light (400–750) nm illumination for high sensitivity
  • Transmittance and reflectance collection for imaging a wide variety of samples
  • Powerful, user-friendly Quantity One software for image acquisition and data analysis
  • Sealed platen for imaging of wet samples
  • Modified transparent lid for safely imaging samples of variable thickness

Flexible High-Resolution Imaging

The GS-800 calibrated densitometer provides quantitatively accrate, high-quality imaging to detect and resolve even the faintest bands. With user-selectable scan resolution down to ‎‎36.3 µm, you can preview and scan your samples in seconds. Variable resolution also ‎allows you to control both the scanning time and image file size.

High Sensitivity

The GS-800 calibrated densitometer offers high sensitivity. The color CCD camera can scan in red, green, or blue, and scans virtually any sample (1-D and 2-D gels, colorimetric dot and slot blots, film-based chemiluminescent blots, autoradiograms, slides, and photographs) at the ideal wavelength for greatest sensitivity and accuracy.

Transmittance and Reflectance

Unlike laser densitometer systems, the GS-800 calibrated densitometer has both transmittance and true reflectance capabilities that allow accurate scans of both transparent and opaque samples. The advantage of true reflectance scanning is the accurate detection and analysis of molecules on the surface of membranes, rather than molecules distributed throughout the membrane matrix. True reflectance provides the most accurate detection and analysis of dot blots, slot blots, and other electrophoretic blots without quantitation errors.
