Product description

Scientific-grade ImmunoSpot S6 Universal M2 analyzer with brightfield, fluorescence imaging, and ELISPOT analysis capabilities.

The CTL ImmunoSpot S6 Universal M2 Analyzer is a specialized laboratory instrument designed for precise cell counting, brightfield and fluorescence imaging, and ELISPOT/FluoroSpot analysis crucial in biotechnology and molecular diagnostics workflows. Equipped with a scientific-grade camera, this unit supports multiple plate formats including 6-, 12-, 24-, 48-, 96-, and 384-well plates, enabling flexible throughput for diverse bioprocessing and cell biology research applications.

Key technical specifications include:

  • Illumination system: Dual white light sources and a fluorescence light source optimized for multiplex fluorescent assays.
  • Excitation wavelengths: 405, 480, 570, and 630 nm to cover a broad spectrum of common fluorophores used in synthetic biology and gene editing studies.
  • Emission filter changer: 9-position motorized, supporting various emission bands (440, 520, 600, 670, 690, 800 nm), compatible with dyes such as DAPI, FITC, PE, Cy5, and APC, enabling multi-color fluorescence analysis.
  • Optical interface: Motorized zoom and lens system allowing precise focus and image acquisition for reproducible results essential in single-cell analysis and molecular cloning workflows.
  • Designed for live/dead/apoptotic PBMC counting, the analyzer offers reliable fluorescence and brightfield imaging necessary for cell quantification in biomanufacturing and clinical diagnostics.

This analyzer comes complete with a desktop PC running the proprietary ImmunoSpot software suite facilitating automated image acquisition and data analysis. It is widely adopted in biomedical engineering and immunological research fields where high throughput and accuracy in cell-based assays are critical.

Overall, the ImmunoSpot S6 Universal M2 Cell Counter Analyzer integrates multiple excitation and emission options, motorized optics, and versatile plate compatibility, making it an essential instrument for labs conducting live-cell imaging, fluorescence analysis, and advanced ELISPOT-based molecular diagnostic assays. Its robustness and flexibility make it ideal for research environments focusing on biopharmaceutical production pipelines and innovative biotechnological developments.

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.
