ZR-1101 Automatic Colony Counter

Short Description:

ZR-1101 Automatic Colony Counter, built in 12 megapixel CMOS camera. Ensure the clarity and speed of the colony image. Truly reduce the working load of staff and realize efficient and fast counting of microorganisms. Automatic Colony Counter is used in the food, environmental, pharmaceutical, cosmetics, veterinary and public institutes research.

  • Camera: 12 megapixel. Resolution Ratio: 4024*3036
  • Minimum size of detected colony: 0.05 mm
  • Petri dish specification: Counting on various 90mm,100mm petri dishes
  • Image processing:  Counting on pour, surface, Spiral, circle mode plated Petri dishes
  • Product Detail


    The automatic colony counter ZR-1101 is a high-tech product developed for microbial colony analysis and micro-particle size detection. The powerful image processing software and scientific arithmetic enable it to analyze microbial colonies and detect micro-particle size, the counting is quick and accurate.



    • Hospitals, scientific research institutions, health and anti-epidemic stations, and disease control centers.

    • Inspection and quarantine, quality and technical supervision, and environmental testing institutions.

    • Pharmaceutical, food and beverage, medical and health supplies industries.


    • 21 CFR Part 11 included

    > The software complies with FDA recommendations, particularly on audit trail and security of results.

    The user account management, integrated in the software, allows the creation of up to 4 levels of rights. Password management secures user accounts.


    • Fully enclosed multiple lighting

    The cabin is completely closed to avoid external light interference, providing necessary light and shadow conditions for accurate colony counting.

    Bulit-in 254nm and 365nm Ultraviolet lamp, can sterilize dishes and cabins, UV mutagenesis and fluorescence excitation experiments can also be realized.

    Capture high-definition colonies quickly.

    The operator does not tire his eyes.

    • Accuracy and Repeatability

    > ZR-1101 can count up to 1000 colonies in 1 second in a constant and repeatable mode. Counting accuracy reach up to 99%. The minimum colony size is 0.12 mm.

    > Realize polychromatic plate dyeing to identify colonies.

    • Accurate segmentation and identification of adhesive colonies

    • Scan code and print to standardize data record
