HD1600AI Intelligencecolony counter

HD1600 is the latest product from Xunshu Technology, a high-definition colony counter equipped with AI artificial intelligence. The research team carefully screened and summarized, and established a colony image dataset. After hundreds of neural network training and model parameter adjustments, they obtained high-precision and highly robust engineering software that can quickly and batch solve colony counting of various petri dishes.

The instrument adopts a delicate, sturdy, and well cooled all metal architecture design, with rich lighting paths: high contrast suspended dark field lighting, fog gradient diffuse lighting, oblique backlight lighting, and dual path dual wavelength dyeing lighting. Digital imaging consists of a high-resolution fixed focus lens and a high pixel CMOS sensor, resulting in sharp images and natural colors.

•AI artificial intelligence high-precision automatic colony counting

The broad representativeness and effectiveness of big data are important foundations for determining the accuracy of AI. The Xunshu AI colony analysis system, based on 20 years of promotion and accumulation of massive user colony images, has been trained with high computing power through neural networks to form a fast, stable, and high-precision large model. It can not only accurately count conventional petri dishes, but also achieve accurate counting of dishes with strong adhesion and high interference from impurity backgrounds.

Main functions and technical indicators

1lighting system

•Fully enclosed steel aluminum alloy chassis (32 × 34 × 46cm): precise and sturdy, ensuring a light tight seal

•Flat dish sample compartment: aluminum alloy frame, pull-down partition window, eliminates environmental stray light interference, blocks UV leakage, and prevents dust from entering

•High contrast floating dark field illumination

Circular layered LED broadband retroreflection highlights the contour and color of bacterial colonies in the dark field, keenly capturing micro colonies on the surface and deep layers of the culture medium

•Color transparent backlight illumination

•Adjustable LED light guide array, forming uniform and bright 5 color transmitted light, enhancing the contrast between bacterial colonies and culture medium

•Illumination uniformity greater than 90%, ensuring uniform illumination at the edges and center of the culture dish

•Fog gradient diffuse reflection illumination

•Circular LED forms a large area of fog diffuse illumination through the guidance and uniform light diffusion of nanomaterials

•Natural display of colony color, texture, and transparency, with no colonies presentShadows eliminate the light spots and halos formed by the refraction of glass plates

•Light staining illumination (dual path dual wavelength)

Two wavelengths of light are irradiated at different angles on the petri dish to achieve light staining of colonies and culture media (filter membranes), improving the accuracy of colony recognition and counting.

•UV disinfection: High power deep ultraviolet UVC-LED, instant sterilization, does not produce ozone, stable light efficiency, long lifespan

•Light source controller

4、 AIdata management

1. Multi user, multi project management

Ø A multi-user system can be created, where each user logs in with an independent username and password to ensure personal data isolation.

Ø The experimenter can create multiple engineering files for different projects during each experiment. Each project can achieve batch shooting of petri dishes, automatic batch colony counting, verify counting accuracy, and generate electronic data. Multiple project files can be switched, called, and managed at any time.

2. Data Information Management

Ø The electronic data generated by the analysis system is saved, backed up, restored, and retrieved in the form of engineering files.

Ø All engineering file data is deeply hidden to prevent illegal deletion, modification, or theft, ensuring the security of the files.

Ø The electronic data within a single engineering file consists of sample registration information, statistical result information, test reports, and a set of petri dish images of batch labeled colonies. Sample registration includes: sample name, number, report name, testing unit, sending unit, testing personnel, and testing date. The statistical results include: dish number, dish name, number of identifications, dilution factor, and total conversion. The test report can be output in PDF or Excel format.

Ø Data backup and recovery: The system can back up engineering files to external media or restore files from external media to the system. Backup and recovery cover all statistical data, images, and other information of the original engineering files.
