The E7500 is the Accuris QuadCount Automatic Cell Counter — a benchtop automated cell-counting instrument that replaces the manual hemocytometer workflow with image-based automated cell enumeration on dedicated QuadCount slides. The instrument ships with the QuadCount main device + USB memory stick (containing Quick manual + Instruction manual PDFs) + main power cable as the base package; optional add-on accessories (QuadCount Slides 50/box, Keypad, Barcode scanner, Thermal printer, Backup Slides, Stain reagent) are sold separately. Sized for cell-culture labs, stem-cell research, immunology, and any workflow that requires routine cell counting plus viability assessment.
Voltage options: This unit can be ordered with European voltage requirements (230V/50Hz). Contact us to order.

What This Instrument Does
The QuadCount automates the manual hemocytometer cell-counting workflow:
- Sample prep — mix the cell suspension with trypan blue or compatible viability stain (live cells exclude the dye; dead cells uptake the dye and stain blue)
- Slide loading — pipette the stained suspension into the QuadCount slide chamber
- Slide insertion — insert the QuadCount slide into the instrument
- Automated counting — the instrument acquires images of the slide chamber and applies image-recognition algorithms to count cells, distinguishing live (unstained) from dead (blue-stained) cells
- Result readout — total cell count, live/dead ratio, cell concentration, and percent viability displayed on the instrument screen and exportable via USB
The QuadCount delivers substantially faster counting (typical workflow: <30 seconds per slide) vs manual hemocytometer counting (typical 5-10 minutes per slide for trained operator); it also delivers counting consistency that manual methods don't match (operator-to-operator variation eliminated; image-recognition algorithm applies the same counting criteria to every slide).
Compatibility & Configuration
Cell-culture lab workflows — routine cell counting before splitting, seeding, transfection, or freezing; viability assessment during cell-culture passage decisions.
Stem-cell research — viability and density assessment during stem-cell expansion and differentiation workflows.
Immunology and flow cytometry prep — cell counting and viability QC before flow cytometry sample prep where cell concentration and viability are critical for accurate downstream analysis.
Pharmacology and drug-screening workflows — cell counting and viability assessment for cytotoxicity studies and drug-treatment dose-response workflows.
Educational and training cell-biology programs — cell-biology curricula teaching cell-counting methodology benefit from the automated workflow.
Multi-user core facilities — shared cell-counting instruments where the automated workflow's operator-independence reduces inter-user variability.
Configuration & Accessory Stack
QuadCount Slides (E7500-S1, 50/box) — the dedicated slide format for the instrument. Operator-supplied per workflow throughput; typical lab orders 1-2 boxes (50-100 slides) per quarter at routine cell-counting throughput.
Keypad (optional) — external keypad for sample-ID entry during high-throughput counting workflows.
Barcode scanner (optional) — barcode-based sample tracking for clinical-research and biobank workflows.
Thermal printer (optional) — on-instrument printed result tickets for workflows that don't use USB / digital data export.
Stain reagent (E7500-STS1) — Accuris-branded stain reagent (typically trypan blue or compatible viability stain) for workflows that don't supply their own staining reagent.
Backup Slides (E7500-BS) — backup / spare slide inventory for facilities running heavy-duty counting workflows where slide-quality issues can disrupt workflow.
Frequently Asked Questions
What comes in the base package of the E7500 QuadCount? The base package includes the QuadCount main device, a USB memory stick (with the Quick manual and Instruction manual PDFs), and the main power cable. Slides, stain reagent, keypad, barcode scanner, and thermal printer are optional accessories sold separately.
How much faster is the QuadCount than a manual hemocytometer? A typical QuadCount count takes under 30 seconds per slide, versus roughly 5–10 minutes per slide for a trained operator using a manual hemocytometer — and it removes operator-to-operator counting variation.
What slides does the E7500 use? It uses dedicated QuadCount slides (E7500-S1, 50/box). A typical lab orders 1–2 boxes per quarter at routine counting throughput.
How does the QuadCount tell live cells from dead cells? The cell suspension is mixed with trypan blue or a compatible viability stain — live cells exclude the dye while dead cells take it up and stain blue. The instrument's image-recognition algorithm counts each population and reports viability.
Can the E7500 run on European voltage? Yes. A 230 V / 50 Hz variant is available by special order for international outlets.
Ordering & Configuration
Power configuration. 115 V (this SKU) for North American outlets; a 230 V variant is available by special order for UK / Europe / Australia outlets.
Slide procurement planning. Confirm at order: expected counting workflow throughput (drives slide-purchase quantity sized to reorder cycle); whether the lab supplies its own stain reagent or needs the E7500-STS1 stain accessory.
Workflow integration. Confirm at order: data-export workflow (USB-based digital export; optional thermal printer for printed tickets), barcode workflow integration (optional E7500 barcode scanner), and any institutional sample-tracking integration requirements.
Confirm at quote: voltage configuration (115 V standard; 230 V variant by special order for international outlets), accessory pairing (slides, stain reagent, optional keypad / scanner / printer), workflow throughput, training requirements, and lead time.
Warranty: Per Accuris standard warranty terms — confirm at quote.
