I. Product Introduction

II. Performance Indicators

1. Imaging Unit

• Fully enclosed dark box to eliminate interference from ambient stray light

• Three-color LED visible light source

• Built-in 254 nm UV lamp for cavity sterilization, disinfection and mutagenesis

• Built-in 366 nm UV lamp to excite colony fluorescence, suitable for Escherichia coli counting, green fluorescent protein observation, etc.

• ★ Brightness and on/off status of upper and lower light sources freely adjustable via software

• ★ Light intensity freely adjustable; lighting schemes can be saved for easy recall

• 20-megapixel ultra-clear color camera

• 12-megapixel 12 mm high-definition lens

• ★ Minimum detectable colony: 0.04 mm

• ★ Counting accuracy: ≥ 98%

• ★ Counting speed: 1200 CFU/S

• Suitable petri dish diameter: standard 90–100 mm (smaller dishes centered in the aperture)

2. Software Functions

1) One-click counting with 7 classification modes

• One-click counting for discrete colonies

• One-click counting for confluent colonies

• One-click counting for micro-colonies

• One-click counting for large colonies

• One-click counting for black grid (Compact Dry™)

• One-click counting for grid filter membrane (RIDA™)

• One-click counting for low-contrast colonies (similar to background)

2) Auxiliary Statistical Tools

• Manual correction: add or delete missed colonies by double-click or drag selection

• Intelligent correction: AI-assisted correction based on one-click counting results

• Measurement tools: angle, distance, area, curve

• Impurity removal: eliminate contaminants by color, diameter and roundness

• Single colony analysis: displays roundness, diameter, perimeter, area of individual colonies

• Overall colony statistics: summarizes morphology of all colonies on the plate

• Colony size classification: 25-level display by colony size

• Total colony conversion: automatic calculation based on actual dish diameter and sample dilution factor

3. Data Security and Management

• Multi-user login system with independent, long-term stored data for each account

• Results exportable in PDF format; raw data unalterable

• Audit trail function: automatically records all operations for full data traceability

4. Light Source Management

• Independent control: upper and lower lights can be switched on/off separately

• ★ Brightness adjustment: free fine adjustment (1% precision) via software to meet different contrast requirements

• Mode switching: selectable among upper light only, lower light only, dual light on, etc.

• ★ Scheme save/recall: custom light settings (on/off status and brightness) can be saved and recalled for consistent reuse, greatly improving efficiency and result stability
