1. Purpose:

Used for fully automated colony counting analysis, and can also be used for automatic particle counting analysis in microscopic images

2、 Main performance parameter indicators:

1 ★Imaging host

1）Large depth of field for autofocus8 million pixel (3264x2448 pixel) color camera, equipped withHas macro shooting characteristics

2) Fully enclosed dark box to eliminate environmental stray light interference
3) Flexible shadowless upper light source（Adjustable 20 color LED surround structured light+8-level brightness adjustment）, to create a clear suspended dark field colony imaging effect
4) Uniform and shadowless illumination from a lower light source to highlight the morphology of bacterial colonies and achieve intelligent recognition and counting in a foolproof manner
5) Up light source, down light source, dual light source, UV light source, can be freely combined and switched to obtain the best colony imaging

6) Suitable culture dish: 50-150mm (pouring, coating, membrane filtration, spiral petri dish, 3M paper sheet)

2 Colony count analysis

1）★Automatic recognition and statistics: SmartdownTM colony intelligent recognition technology automatically recognizes large scale clustered and chain shaped adhered long rod-shaped bacteria (microscopic morphology of large adhered Escherichia coli, bacterial spores) and various types of colonies on petri dishes (including Staphylococcus aureus count (GB4789.10-2016), Escherichia coli group determination (GB4789.3-2016), etc.).Automatically generate batch processing wizard to achieve one click automatic counting

2) The automatic counting accuracy is ≥ 96.5%, with a maximum monitoring correction of 3.5%, achieving 100% accuracy. Analysis and statistics speed: 150-800 colonies/s, with a total imaging and counting time of ≤ 5 seconds for each dish when analyzing 2 dishes

3）★Colony adhesion segmentation: Automatically segment long, circular, and other colony targets that are adhered to each other, and users can choose to segment or not segment them. It is also possible to manually segment and merge colony target images

4）★Color and shape recognition:Equipped with fast level set extraction technologyIt can identify and count the number of colonies of specific colors and shapes according to 20 categories, and can be corrected by category conversion. 6 target areas can be selected simultaneously for automatic analysis, and the analysis target areas can be freely increased, decreased, or edited

5) Colony morphology analysis: Automatically obtain colony area, equivalent diameter, major axis, minor axis, aspect ratio, roundness, perimeter, shape factor, etc. You can filter and query based on morphological indicators.

6）★Mouse click correction,Untrace removal of grids and textAutomatically remove impurities, effectively support complex microbial statistics, and comply with the parameter automatic conversion characteristics of GB4789.2-2016.

3 Export Query and Upgrade:The analysis of images and data results can be saved and automatically generate Excel or PDF document reports. Has online upgrade feature.

4 Measurement functions:Fully automatic size calibration, also available for manual calibration. Accurate measurement of length, angle, radian, area, arc, and any curve can be achieved by dragging with the mouse.

5 ★ Data traceability and permission protectionSystem administrators can assign usage permissions to more than 10 operators, and operation records can be traced back,Compliant with GLP and GMP requirements.

6 configurations：

1) Wanshen HiCC series fully automatic colony counting analysis software, lock 1 set

2）One 3264x2448 pixel color camera with autofocus and large depth of field (switchable between floating dark field and backlight)

3) Brand computer (Core i5 CPU/8GB memory/500G hard drive/19.5 "color display/wireless network card, Windows operating system environment) 1 unit
