What Is the CellInsight CX7?
The Thermo Fisher CellInsight CX7 is a benchtop high-content analyser (HCA) built for automated multi-well fluorescence imaging. It is used across UK pharma, biotech and academic labs for Cell Painting, compound profiling, toxicity screening and phenotypic drug discovery.
Two main configurations are sold in the UK:
- CellInsight CX7 Pro — laser excitation, more fluorescence channels, higher-end configurations for complex multi-parametric assays.
- CellInsight CX7 LED Pro — LED excitation, fewer but sufficient channels for standard Cell Painting and high-content assays at a lower price point.
This review explains how the CX7 fits into a Cell Painting workflow, what it costs in the UK, and how it compares to alternatives such as the Yokogawa CV8000, Molecular Devices ImageXpress and Revvity Opera/Operetta. As always, Plankton & Zoom does not sell microscopes; we compare them so you can request the right demonstration and quote from an authorised distributor.

Why the CX7 Is Popular for Cell Painting
Cell Painting measures the morphological response of cells to genetic or chemical perturbation by staining six cellular compartments with fluorescent dyes. The resulting multi-channel images are then analysed with tools such as CellProfiler or HCS Studio to extract thousands of features per cell.
The CellInsight CX7 is well suited to this because it can:
- Acquire five to seven fluorescence channels plus transmitted light in a single pass.
- Image entire multi-well plates unattended, making overnight Cell Painting runs practical.
- Maintain live cells with optional environmental control for time-course assays.
- Export images and metadata in formats compatible with CellProfiler, pycytominer and downstream machine learning pipelines.
- Scale from exploratory biology to screening, which suits both academic labs and pharma target-validation teams.

What We Like About the CellInsight CX7
- Mature software ecosystem: HCS Studio is a long-standing platform with established protocols, segmentation tools and reporting templates.
- Flexible illumination: Choose LED Pro for cost and simplicity or Pro for laser stability and extra channels.
- Good Cell Painting integration: The JUMP Cell Painting Consortium and Broad Institute workflows have been run on Thermo Fisher high-content systems.
- Environmental options: Live-cell time-lapse and long kinetic assays are possible with the right configuration.
- UK support network: Thermo Fisher Scientific UK has field service engineers and applications scientists for installation and training.
Limitations to Consider
- Widefield, not confocal: Thick samples or organoids may suffer from out-of-focus light; thin monolayers are ideal.
- Price step from entry HCA: A CellInsight CX7 is a major capital purchase. Labs with modest throughput may first use a benchtop inverted fluorescence microscope such as the EVOS M7000.
- Consumable and software costs: Multi-well plates, reagents, analysis modules and annual support contracts add to total cost of ownership.
- Data volume: Cell Painting generates large image sets; labs need storage, backup and analysis infrastructure.
CellInsight CX7 vs Alternatives
| System | Best for | Key differentiator |
|---|
| CellInsight CX7 LED Pro | Standard Cell Painting, phenotypic assays | Cost-effective LED widefield HCA |
| CellInsight CX7 Pro | Complex multi-channel screening | Laser excitation, more channels |
| Yokogawa CV8000 | Confocal high-throughput screening | Spinning-disc confocality and speed |
| Molecular Devices ImageXpress | Large screening campaigns | Integrated analysis and screening workflow |
| Revvity Opera Phenix / Operetta | Confocal phenotypic screening | Confocal optics, water-immersion options |
| EVOS M7000 | Benchtop fluorescence / small-scale Cell Painting | Lower cost, manual plate handling |
For labs beginning Cell Painting, an EVOS M7000 or CellInsight CX7 LED Pro can be a sensible first step before moving to a confocal screening platform.
UK Demo, Quote and Purchase Guidance
The CellInsight CX7 is sold in the UK by Thermo Fisher Scientific and authorised distributors. A purchase decision should include a sample run on your own cells, a total-cost-of-ownership review covering installation, training, service contract and software modules, and confirmation that the quoted configuration can run your planned assay menu.
Typical UK lead times range from 8 to 16 weeks for a new system, depending on configuration and stock. Ask whether the quote includes VAT, delivery, installation, training and a first-year service plan.
Frequently Asked Questions
How much does the CellInsight CX7 cost in the UK?
Expect £85,000 to £180,000 ex-VAT depending on Pro vs LED Pro, laser channels, objectives, environmental control and software modules.
What is the difference between CellInsight CX7 Pro and LED Pro?
LED Pro uses LED excitation and is ideal for standard Cell Painting and assays. Pro uses laser excitation, supports more channels and is aimed at demanding multi-parametric screening.
Can the CellInsight CX7 do Cell Painting?
Yes. Its multi-channel widefield imaging, automated stage and software export make it a common choice for the six-dye Cell Painting protocol.
How does CellInsight CX7 compare to the Yokogawa CV8000?
The CV8000 is a confocal spinning-disc system for very high-throughput confocal screening. The CX7 is a widefield HCA that is generally more cost-effective for standard Cell Painting and phenotypic assays.
