Why Semiconductor
Biosensor Technology?

Traditional cell counting relies on optical lenses — limiting FOV, increasing cost, and demanding precise alignment. SOL COUNT replaces optics with lens-free CMOS biosensors: a semiconductor revolution in life science tools.

Conventional Lens-Based Counter

  • Limited field of view (1 mm²)
  • Requires mechanical focus per sample
  • Proprietary disposable slides — high cost
  • Bulky benchtop footprint
  • Human error in manual counting
  • CV% 12–16% (hemocytometer)

SOL COUNT — Lens-Free Semiconductor

  • Full-chip FOV: 10.02 mm² — 10× larger
  • No focusing, no optical alignment needed
  • Cost-effective 4-channel disposable cartridge
  • Ultra-compact: 180×120×78 mm, 820 g
  • Automated counting — eliminates human error
  • CV% as low as 3.39% — statistically superior

SOL COUNT's semiconductor CMOS sensor images the entire chamber in a single capture — no tile stitching, no missed events, delivering statistically more robust counts across all concentration ranges.
Core Features

Designed for Effortless
Cell Counting.

Built around a single principle: scientists should spend time on biology, not calibrating instruments.

≤10 Seconds per Channel

From sample loading to cell count result — under 10 seconds per channel. Software automatically processes, counts, and displays results.

Dual-Sample Simultaneous Count

2 samples loaded in 1 shot → 2 results at the same time. The 4-channel cartridge enables multiple measurement conditions simultaneously.

Live / Dead Viability Analysis

Trypan blue staining identifies live and dead cells automatically. Validated on K562, Vero, CHO-K1, and Jurkat cell lines with results equivalent to hemocytometer.

SOLOUD Cloud Platform

Wireless sync to SOL's cloud server. Access results from laptop, phone, tablet, or desktop. Real-time monitoring, data comparison, and team co-working.

One-Click Reporting

Export results in PDF, JPG, or Excel/CSV — including total count, live/dead concentration, viability %, and original + result images. LIMS-ready format.

Automatic S/W Update

When connected via Wi-Fi or Ethernet, SOL COUNT automatically prompts and applies firmware updates, continuously improving AI models and counting accuracy.

How It Works

Results in 4 Easy Steps.

Prepare sample → Load → Get results. The simplest cell counting workflow in the lab.

1

Prepare & Load Sample

Mix cell suspension 1:1 with 0.4% trypan blue. Pipette 10 μL into each cartridge chamber at 45° angle.

2

Insert Cartridge

Push the SOL COUNT tray to open, place the loaded cartridge into the unit, then push the tray back in.

3

Capture & Count

Press "Cell Counter" on the touchscreen. Results appear in ≤10 seconds — total, live, dead counts + viability %.

4

Save & Transfer

Save to USB drive or sync to SOLOUD cloud server. Export PDF report or Excel file with one click.

Scientific Validation

Precision You Can
Publish.

SOL COUNT's performance was validated against the hemocytometer (manual gold standard) across multiple cell lines and concentration ranges. The data speaks for itself.

Linearity — SOL COUNT vs Hemocytometer

R² (Correlation) 0.9994
Regression slope 1.0262
Concentration range tested 1×10⁴ – 1×10⁷ cells/mL
Cell line K562 (mammalian)

R² ≥ 0.99 confirms near-perfect correlation with hemocytometer across the full measurement range. Slope of 1.0262 indicates minimal systematic bias.

CV% Comparison — Precision at All Concentrations

ConcentrationHemocytometer CV%SOL COUNT CV%
High (~9.4×10⁶)12.91%3.39%
Med-High (~4.9×10⁶)12.41%4.73%
Med-Low (~2.6×10⁶)15.63%5.53%
Low (~0.4×10⁶)15.81%6.55%

Lower CV% = higher precision. Acceptable CV% threshold is <10% for statistically significant results. SOL COUNT consistently outperforms hemocytometer and lens-based competitors (n=10 each concentration).

Viability Validation — 4 Cell Lines

SOL COUNT viability measurements were validated at high (90%), medium (60%), and low (20%) viability conditions using trypan blue staining. Results were equivalent to hemocytometer across all four tested cell lines: K562, Vero, CHO-K1, and Jurkat. The imaging results match microscopy images, confirming accurate live/dead discrimination.
