Bio-Rad GS-900 Calibrated Densitometer

**Pre-owned, good condition.

The GS-900 Calibrated Densitometer is designed to reproducibly image gels, blots, and film and quantitate proteins across a wide dynamic range. The GS-900 Densitometry System uses transmissive and reflective imaging to scan chromogenic samples at the optimal detection wavelength. The three-color red, green, and blue CCD imaging technology enables accurate, reproducible quantitation with a wide variety of common stains.

To meet cGMP environment needs, the GS-900 Densitometer offers a security edition software module for 21 CFR 11 complliance and an Installation and Operations Qualification (IQ/OQ) Kit.

Applications and Uses

• Imaging of diverse samples on 1-D and 2-D gels, colorimetric dot and slot blots, film-based chemiluminescent blots, and autoradiograms
• Protein quantitation for Coomassie Blue- and silver-stained gels over a wide dynamic range of 0–3.4 OD
• Scanning large gels — oversized 29 × 33 cm imaging area
• Rapid image acquisition and analysis with intuitive, user-friendly Image Lab Software

Features and Benefits of the GS-900 Calibrated Densitometer

• Automatic self-calibration before each run
  • The GS-900 Calibrated Densitometer uses built-in NIST-traceable step tablets for internal calibration to ensure the accuracy of each scan
  • Internal calibration can be validated with an external NIST-traceable target to confirm accuracy and reproducibility using the GS-900 Calibrated Densitometer Installation and Operations Qualification Kit (1707994)
  • One-touch operation button for further ease of image acquisition
• Image Lab Software greatly simplifies image analysis
  • Automated analysis saves time and ensures consistency between runs
  • Includes detailed tutorials; no previous imaging experience required to produce optimum gel and blot images
  • Flexible analysis — simply modify user settings to match SOPs and fine-tune band detection, background level, and other settings
  • Easy reporting with the ability to create customized reports
• Meets 21 CFR Part 11 regulatory requirements with an optional Image Lab Software Security Module (1709691)
• 16-bit precision and 36.3 μm resolution for the analysis of very close bands on a gel
• Sealed imaging area to accommodate wet samples of variable thickness
