Fully Automated Colony Counter
I. Product Introduction:
This product is an automated colony counting instrument integrating image acquisition, data processing, and statistical analysis. It is widely used in colony counting in the food, pharmaceutical, cosmetic, environmental monitoring, medical and health, and scientific research fields. The instrument employs advanced digital image processing technology and features fluorescent bacteria identification and sterilization functions. It can achieve rapid, accurate, and fully automated counting of colonies in petri dishes, significantly improving experimental efficiency and reducing human error.
II. Performance Indicators
1. Imaging Device
Fully enclosed dark chamber, eliminating stray light interference from the external environment.
360° ring-shaped four-color LED visible light, providing shadowless soft illumination.
Built-in 254nm UV lamp for sterilization and mutagenesis of the chamber.
Built-in 366nm UV lamp to excite colony fluorescence, meeting the needs of Escherichia coli counting and green fluorescent protein observation.
★Upper and lower light source brightness and on/off control can be directly adjusted via software, eliminating the need for mechanical switches.
★Light source schemes can be saved and historical schemes can be directly recalled without repeated settings.
20MP ultra-high-definition color camera;
12MP 12mm high-definition lens
★Smallest detectable colony size: 0.05mm
★Counting accuracy: ≥98%
★Counting time: 1200 CFU/s
Suitable petri dish diameter: Standard 90-110mm (smaller petri dishes should be placed in the center of the aperture).
2. Software Functions
1) One-click counting with 7 classification modes:
One-click count for dispersed bacteria
One-click count for adherent bacteria
One-click count for tiny bacteria
One-click count for large colonies
One-click count for black grid (Compact Dry™)
One-click count for grid filter membrane (RIDA™)
One-click count for bacteria with similar background
2) Auxiliary statistical tools
Manual correction: Double-click to add or delete missed colonies; select to add or delete missed colonies.
Intelligent correction: Intelligent correction can be performed based on one-click statistics.
Measurement tools: Angle, line segment, area, curve
Contaminant (impurity) removal: Remove impurities based on color, diameter, and roundness.
Single colony morphology analysis: Click on a single colony to obtain information such as roundness, diameter, perimeter, and area.
All colony morphologies: After statistics are completed, information such as roundness, diameter, perimeter, and area of all colonies on the plate can be obtained.
Colony size classification: After statistics are completed, based on... Each colony outline size is displayed in 25 categorized levels.
Sample colony total conversion: Automatic conversion based on actual petri dish diameter and sample dilution.
3. Data Security and Management
Multi-user login system; each account generates independent data, which is permanently stored.
Statistical results are output in PDF format; original data cannot be altered.
Audit trail function is provided; the software automatically records every step of the operator's operation for subsequent data traceability.
Built-in bilingual display (Chinese and English) with one-click switching.
The instrument has cloud platform support, allowing analysis data to be saved to the cloud for viewing anytime, anywhere.
4. Light Source Management
This series of fully automatic colony counters is equipped with a flexible upper and lower dual light source system. Users can freely adjust the light source using software to obtain the best imaging effect according to different petri dish types, colony characteristics, and background conditions.
Specific functions include:
Independent control: The upper and lower light sources can be turned on or off independently.
★Brightness adjustment: No mechanical switch control is required; the brightness of each light source can be freely adjusted directly in the software, with fine-tuning (accurate to 1%) to adapt to different contrast requirements.
Mode Switching: Users can freely switch between various lighting modes such as "upper light only," "lower light only," and "both upper and lower lights on simultaneously."
★Scheme Saving: Users can save their customized light source combinations (including on/off status and brightness) as custom schemes. When encountering the same type of sample again, this scheme can be directly recalled without repeated settings, greatly improving work efficiency and result consistency.
5. Calibration Function
To ensure the accuracy of measurement results, this series of fully automatic colony counters provides a reliable size calibration function, converting pixel units on the image into actual physical dimensions (such as millimeters), thereby ensuring the accuracy of measurement data such as colony diameter and area. This function has two modes: automatic calibration and manual calibration, to meet the needs of different users and scenarios.
