Manual haemocytometers are slow, operator-dependent and hard to standardise across a team. An automated cell counting microscope captures digital images of your suspension and returns total count, viability and size distribution in seconds. For UK tissue-culture labs, this means faster QC, better reproducibility and more time for actual research.
Systems fall into two groups: imaging microscopes with counting software (EVOS, LUNA-FL) and dedicated benchtop counters (Countess 3, LUNA-II, EVE Plus, CellDrop). Imaging systems cost more but add fluorescence, confluence and publication images. Dedicated counters are cheaper and faster for pure counting. The right choice depends on throughput, cell types and whether you need downstream imaging.
Quick takeaway: the EVOS M3000 is the best-value imaging-based automated cell counter for most UK labs, while the LUNA-II is the standout low-cost dedicated counter. Choose based on whether you need fluorescence imaging or pure counting speed.
Compare Automated Cell Counters by Workflow
Not every UK lab needs the same kind of cell counter. Picking the right instrument is easier when you match your workflow to the product category rather than comparing spec sheets line by line.
1. Pure Brightfield Counting
Best for: routine mammalian cell lines, GLP/GMP traceability, high sample throughput where imaging is not required.
These benchtop counters use trypan blue to distinguish live and dead cells in under 20 seconds. They are the cheapest to buy and run, take up little bench space and are simple enough for multi-user suites.
- LUNA-II — best-value brightfield counter; optional built-in printer for paper records.
- Countess 3 — fast, touchscreen-driven counter with optional fluorescence upgrade (Countess 3 FL).
Budget signal: £2,500–£4,000 for LUNA-II; £8,000–£15,000 for Countess 3 (exc. VAT).
2. Imaging + Counting
Best for: tissue-culture labs that want cell images for lab books, confluence checks, GFP/RFP reporter assays and publication figures alongside automated counts.
These systems combine a digital microscope with on-board analysis. They cost more than dedicated counters but replace a separate microscope and camera, so the total bench footprint and training time often fall.
- EVOS M3000 — standalone inverted microscope with counting, confluence and two-channel fluorescence.
- LUNA-FL — compact brightfield + dual fluorescence counter for viability dyes and GFP.
Budget signal: £4,500–£6,500 for LUNA-FL; £8,995–£10,500 for EVOS M3000 (exc. VAT).
3. Live-Cell, Multi-Well and High-Content Screening
Best for: long-term kinetic assays, drug-discovery screening, plate-based experiments and labs that need quantification across many conditions automatically.
These platforms still count cells, but their real advantage is unattended imaging across multi-well plates, time-lapse acquisition and advanced analysis. They sit at the top of the price range and normally require a dedicated PC and on-stage incubation.
- EVOS M5000 — four-colour fluorescence, Z-stacking and time-lapse for demanding research.
- EVOS M7000 — plate scanning, on-stage incubation and automated analysis.
- CellInsight CX7 — high-content screening platform for large assay panels.
Budget signal: £12,000–£18,000 for M5000; £22,000–£35,000 for M7000; £50,000+ for CellInsight CX7 (exc. VAT).
How to use this guide: start by deciding which workflow bucket matches your lab, then read the detailed product cards below for UK price bands, seller links and feature comparisons. If you only need fast counts, stay in bucket 1. If you need images too, jump to bucket 2. For plate-based or long-term assays, see bucket 3.

Frequently Asked Questions
What is an automated cell counting microscope?
An automated cell counting microscope captures digital images of a cell suspension and uses software to count cells, measure viability and estimate size distribution — replacing manual haemocytometer counts.
How much does an automated cell counter cost in the UK?
UK indicative prices exclude VAT and delivery. A brightfield-only dedicated counter such as the LUNA-II typically starts around £2,500–£4,000. An imaging-based counter such as the EVOS M3000 usually ranges from £8,995 to £10,500. A dedicated benchtop counter such as the Countess 3 usually falls between £8,000 and £15,000. Multi-channel research systems sit around £12,000–£18,000, live-cell platforms around £22,000–£35,000, and high-content screening systems such as the CellInsight CX7 start around £50,000.
Is the LUNA-II or EVOS M3000 better for cell counting?
Choose the LUNA-II if you only need fast, accurate brightfield counts at low cost. Choose the EVOS M3000 if you also want fluorescence imaging, confluence analysis and publication-quality cell images.
Do I need fluorescence for automated cell counting?
Brightfield counting is sufficient for many routine cultures. Add fluorescence if you need viability dyes, GFP/RFP reporter quantification or nuclear segmentation.
