Calibrated CCD densitometer for quantitative gel, blot, protein, and nucleic acid analysis.
The Bio-Rad GS-900 Calibrated Densitometer is a CCD-based laboratory imaging system for quantitative analysis of proteins, nucleic acids, and other biomolecules on gels and membranes. It is designed for gel documentation, blot quantification, molecular biology, biochemistry, proteomics, and clinical research workflows.
The calibrated optical system provides reproducible, linear densitometry data for quantitative gel and blot analysis, including workflows in molecular diagnostics, biotechnology, and protein research. The system is described as tested, fully operational, and in excellent condition.
Lab equipment markets are fragmented. Buyers spend weeks calling distributors, comparing quotes, and verifying supplier reliability. Sellers struggle to reach global research labs.
We built Questpair to fix this. Every supplier on the platform is verified before listing. Every quote you receive comes from a real, vetted seller. AI prepares your case in minutes, then a real specialist takes over.
We're an independent team based in The Netherlands, working with research labs and procurement teams across Europe and worldwide.
With a service contract, ten to fifteen years is normal for most benchtop instruments. Detectors and pumps are the parts that wear first.
Often, yes. Verified suppliers frequently work with service partners converting the instrument. If applicable, we can list servicing options alongside the offer.
Ask a scientist through the request button. Parts are often available even when the instrument itself is discontinued.
Two to six weeks, depending on refurbishment scope and whether calibration is included.
We ship to 38 countries. Crating and customs handling are quoted with the instrument.
Tell us what you need and a scientist finds it for you, usually within the hour.
