GS-800 Calibrated Densitometer, Bio-Rad (CAT#: STEM-CTEPO-0096-ZJF)

The manufacturer of the GS-800 Calibrated Densitometer, Bio-Rad is Bio-Rad.
Refurbished Bio Rad GS-800 Calibrated Densitometer. (available part numbers: U9901-H9D0, UTA-2100XL & powerlook 2100XL) Optional: PC with software. Variable scanning resolution, 12 bit data collection, dynamic range is 0 to 3.0 OD and 0 to 2.0 RD. Light range 400-750 nm. Transmittance or reflectance. The Bio-Rad GS-800 Densitometer may be used to scan wet or dry gels, x-ray films and images printed from imaging machines. The object to be scanned should be placed on the left end of the scanner with the top aligned with the left edge.
Flexible High-Resolution Imaging: The GS-800 calibrated densitometer provides quantitatively accurate, 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. Item Specifics: The GS-800 calibrated densitometer delivers automatic calibration for superior accuracy, resolution, and image quality.
