Product description

High-resolution CCD gel documentation systems for protein and nucleic acid imaging, supporting fluorescence and colorimetry.

The Bio-Rad Gel Doc XR and Gel Doc XR+ imaging systems are advanced CCD-based gel documentation platforms designed for precise visualization and quantitative analysis of protein and nucleic acid gels, blots, and macroarrays. These systems are widely adopted in molecular biology, biotechnology, and clinical diagnostics, essential for workflows involving PCR product analysis, electrophoresis, genetic fingerprinting, RFLP, and protein characterization.

Key technical specifications include:

  • High-resolution imaging with a 4-megapixel CCD detector and 4.65 µm pixel size for detailed band visualization.
  • Support for fluorescence imaging using an optional XcitaBlue conversion screen, enabling detection of blue-light excitable stains such as SYBR Safe while protecting DNA from UV damage.
  • Multiple illumination modes: epi-white light and trans-UV (302 nm) sources suited for diverse gel types and staining protocols.
  • Capacity to image samples up to 28 x 36 cm with a maximum image area of 19.4 x 26 cm.
  • Software-driven automation with motorized zoom, focus, and iris controls (XR+ model) enhancing repeatability and reproducibility for bioprocessing and molecular diagnostics applications.
  • Flat field correction and dynamic artifact compensation improve quantitative accuracy across repeated experiments and custom protocols.
  • Environmental tolerance suitable for typical laboratory conditions (10–28°C, <70% RH non-condensing).

The Gel Doc XR series supports crucial biotechnology applications such as molecular cloning workflows, gene editing validation, protein purification assays, and biopharmaceutical production monitoring. The integration of software tools for image capture, analysis, and reporting makes it a robust solution for researchers in synthetic biology, neurobiology, and cell biology requiring reliable gel documentation and fluorescence analysis.

Both XR and XR+ models include a darkroom hood, filter slider with standard and optional emission filters, and comprehensive software environments (Quantity One for XR, Image Lab for XR+) engineered for workflow automation and data reproducibility critical in molecular diagnostics and biomanufacturing research pipelines. The XR+ enhances user efficiency with its software-controlled motorized lens adjustments and compatibility with fluorescence protection screens, thereby optimizing DNA visualization protocols for sensitive sample preservation.

In summary, the Bio-Rad Gel Doc XR and XR+ systems provide precise, reproducible imaging solutions that are widely used by molecular biology researchers and biotechnologists conducting live-cell imaging analysis, fluorescence gel documentation, and quantitative protein assays in both academic and industrial laboratory settings.

Why Questpair exists

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.

Frequently asked questions

How long does laboratory equipment typically last?

With a service contract, ten to fifteen years is normal for most benchtop instruments. Detectors and pumps are the parts that wear first.

Can I get service for older equipment?

Often, yes. Verified suppliers frequently work with service partners converting the instrument. If applicable, we can list servicing options alongside the offer.

Where can I buy parts?

Ask a scientist through the request button. Parts are often available even when the instrument itself is discontinued.

What is the typical lead time for refurbished equipment?

Two to six weeks, depending on refurbishment scope and whether calibration is included.

Does laboratory equipment ship internationally?

We ship to 38 countries. Crating and customs handling are quoted with the instrument.
