1 Introduction
The GS-900™ calibrated densitometer is a high-performance imaging instrument
that converts transparent and opaque electrophoretic samples into digital image
data. The GS-900 features calibration to an internal National Institutes of Standards
and Technology (NIST) -traceable reference standard for optimal accuracy and
reproducibility.
The Bio-Rad
®
Image Lab™ software allows control of the instrument and analysis of
resulting images. It also produces reports based on your specified output.
Main Features of the GS-900 Calibrated Densitometer
 Support of both transmissive and reflective scanning modes
 Calibration to internal reference standards (NIST-traceable for transmissive
scans)
 Wide dynamic range:
 Transmissive: 0.0–3.4 OD ( specular )
 Reflective: 0.0–2.7 OD ( specular )
 User-selectable scanning resolution from 36.3 to 127.2 μm
 Images are captured with 16-bit depth for optimal accuracy
 Scanning area of 29 x 33 cm allows imaging of large samples or of multiple
samples at once
