Description from manufacturer:
The GS- 800 Calibrated Imaging Densitometer is a high performance, calibrated  imaging densitometer that converts transparent and opaque electrophoretic samples into digital data. Great for analysis of gels, film, and blots.

Features include:
- Transmissive and reflective imaging using red, green, and blue CCD technology  to scan chromogenic samples at the optimal detection wavelength
- Imaging of a wide variety of samples such as 1-D and 2-D gels, colorimetric  dot and slot blots, film-based chemiluminescent blots, autoradiograms, slides,  and photographs
- IQ/OQ for verification of the reflectance and transmittance calibration  functions
- High resolution and analysis of closest bands on a gel due to 12-bit precision  and 36.3 μm resolution
- Scanning of larger gels for enhanced separation of proteins on oversized 29 x  40 cm sample platen
- Accurate quantitation of samples, such as Coomassie Blue– and silver-stained  gels, over a large dynamic range (0–3.0 OD)
- Sealed imaging platen to accommodate wet samples of variable thickness
- Purity analysis and lane background tools for manufacturing QC
