Product description

The CTL ImmunoSpot S6 Universal M2 Cell Counter Analyzer is a desktop laboratory instrument designed for precise cell counting and advanced imaging applications, including ELISPOT and FluoroSpot assays. Equipped with a scientific-grade camera, it supports both brightfield and fluorescence imaging with motorized zoom optics, enabling high-resolution analysis critical in biotechnology fields such as molecular diagnostics, immunology, and bioprocessing.

Key features include:

  • Compatibility with a range of plate formats: 6, 12, 24, 48, 96, and 384 wells, accommodating varied throughput needs.
  • Illumination system comprising dual white light sources and a multi-wavelength fluorescence light source.
  • Excitation bands at 405, 480, 570, and 630 nm paired with a 9-position motorized emission filter changer supporting fluorophores including DAPI, Alexa Fluor variants, FITC, PE, Cy5, and APC conjugates.
  • Fluorescence filters accommodate complex multi-color imaging essential for single-cell and subcellular analysis.
  • Integrated software suite (ImmunoSpot) includes applications for single and double-color ELISPOT, live/dead/apoptotic PBMC counting, and single-cell fluorescence detection.
  • Motorized zoom/lens and high-precision XY stage ensure reproducible plate well alignment and imaging.

This instrument is widely adopted in biotechnology research, molecular immunology, and clinical diagnostics workflows, being critical for applications such as immune monitoring, biopharmaceutical production pipelines, and synthetic biology assays. It provides robust, reproducible data essential for molecular cloning workflows and fluorescence-based cell quantification.

The system ships complete with a desktop PC running the ImmunoSpot software suite, including monitor, keyboard, mouse, and necessary cables. It is backed by warranty and technical support, with pre-shipment verification ensuring functionality of all illumination, scanning, autofocus, and fluorescence channels.

This cell counter analyzer is essential for laboratories engaged in ELISPOT assay quantification, fluorescence analysis of PBMCs, and multi-color cellular imaging tasks within preparative and analytical bioprocess environments.

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.
