Innovative solution for colony counting accuracy - from continuous gradient dilution to intelligent automatic counting

CFU

CFU， I.e. colony forming unit, is an indicator that describes the number of colonies formed by the growth and reproduction of a single bacterial cell or bacterial cluster on a culture medium. It is widely used in fields such as food safety, water quality testing, and drug production to evaluate the total amount of microorganisms in a sample, achieved by counting the number of colonies on the culture medium.

局限性

CFU count has limitations in reflecting the true number of bacteria, mainly due to the following reasons:

·

Interference from operational errors: In the processes of sample processing, dilution, inoculation, and counting, human operation may cause errors, such as non-standard liquid transfer and counting processes, which may affectThe accuracy of CFU counting is affected.

·

·

Differences in subjective judgments:CFU counting relies on manual visual observation and counting, and the differences in judgment between different observers lead to increased subjectivity and variability in counting results, thereby reducing the accuracy of counting.

Continuous dilution/

To address the aforementioned issues,Inlabtec ConnectionContinued gradient sparsityRelease InstrumentAs a result, it has abandoned the traditional test tube dilution method and instead used a uniquely designed sterile dilution bag for operation. Through quantitative liquid extraction and eddy current flushing technology, it achieves rapid and effective mixing between sample and diluent. In addition, the design of an automatic bag opener and a positioning liquid addition hole avoids human operation errors and reduces pollution risks. It not only simplifies the process, but also improves the convenience, speed, and reliability of the operation and results.

colony counting/In the field of food inspection,colony countingAs a key link, traditional manual counting methods are not only time-consuming and labor-intensive, but also prone to result bias due to subjective judgments and other factors. Although there are many products in the automatic colony counter market, there are generally problems such as complex operation, inability to effectively distinguish impurities and bubbles, insufficient targeting, and difficulty in algorithm optimization.

In response to the above challenges,ICON automatic colony counterDemonstrating significant advantages,ICON not only simplifies the software operation interface, but also has a huge colony morphology library built-in, and continuously updates the library based on AI intelligent learning mechanism, making it easy to distinguish interferences such as bubbles and impurities. This innovative design not only improves the accuracy of counting, but also significantly shortens counting time.

In addition,ICON colony counter can also be customized according to user needs, further meeting specific requirements in different application scenarios！
