Finding the Right GFP Microscope
Green fluorescent protein (GFP) imaging needs a fluorescence microscope with a suitable excitation/emission filter set, a sensitive camera and enough contrast to see dim reporters against autofluorescence. This guide compares the best GFP-capable microscopes for UK labs in 2026.
GFP Filter Basics
For typical GFP you need excitation around 470 nm and emission around 510–525 nm. Many LED fluorescence microscopes include a standard GFP channel. Check that the light cube or filter set is labelled GFP/FITC or similar and that the camera is monochrome for best sensitivity.
Top GFP Microscopes Compared
| Microscope | GFP Channel | Camera | Best For | Price Band |
|---|---|---|---|---|
| EVOS M3000 | LED GFP cube | Integrated monochrome | Routine GFP checks | Under £5,000 |
| EVOS M5000 | 4-colour incl. GFP | High-sensitivity monochrome | Multi-channel imaging | £10,000–£20,000 |
| EVOS M7000 | 4-colour + live cell | High-sensitivity monochrome | Live-cell GFP time-lapse | £20,000+ |
| Nikon Eclipse Ts2-FL | Modular fluorescence | External camera | Upgradeable lab workhorse | £8,000+ |
Why We Recommend EVOS for GFP
- LED light cubes last years: No mercury lamp replacements or warm-up time
- Monochrome cameras: Better sensitivity for dim GFP signals than colour cameras
- Standalone workflow: Capture, measure and export without a separate PC
- Easy filter swaps: Add RFP, DAPI or custom cubes as needs grow
Budget Pick for GFP
For most UK labs doing routine GFP transfection checks, confluence reporting and simple documentation, the EVOS M3000 is the most cost-effective option. It gives you a dedicated GFP channel, cell counting and a touchscreen interface in one compact box.
Where to Buy in the UK
