More Information

The CellStatz Electronic Microbial Growth Analyzer is an intelligent research instrument that integrates constant temperature culture and real-time display of microbial growth processes. By non-invasively and continuously monitoring the capacitively coupled non-contact conductivity value of the system during microbial growth, the instrument can not only automatically generate growth curves with a time resolution of up to seconds but also automatically report the microbial growth rate and acceleration curve as well as the dynamic parameters on the curve. It is an ideal tool for efficient and accurate analysis of growth process information for bacteria, fungi, viruses, microalgae, cells, and other organisms.

Whether these microbial growth processes occur in simple matrices (such as culture media) or complex matrices (such as blood or sludge), the entire analysis process is fully automated, without the need for microbial separation and purification, as well as any physical, chemical, and biological aids and consumables. It has the characteristics of easy operation, good versatility, low application cost, and high accuracy, which can significantly improve the efficiency and input-output ratio of microbial growth-related research.
