    Background:

    • Accurate monitoring of bacterial growth is crucial for various scientific and industrial applications.
    • Existing methods for measuring bacterial concentration can be time-consuming and lack the capacity for high-throughput analysis.

    Purpose of the Study:

    • To introduce a new biophotometer designed for precise and reproducible bacterial concentration measurements.
    • To enable simultaneous monitoring of multiple bacterial cultures at rapid intervals.

    Main Methods:

    • Development of a novel biophotometer instrument.
    • Implementation of high-speed data acquisition systems.
    • Utilization of computer-processing techniques for handling large datasets.

    Main Results:

    • The biophotometer achieves highly precise and reproducible measurements of bacterial concentration.
    • Measurements can be taken at 3-second intervals for each culture.
    • The system supports the simultaneous analysis of 32 bacterial cultures.

    Conclusions:

    • The new biophotometer offers a significant advancement in bacterial monitoring technology.
    • Its high throughput and precision make it suitable for research and industrial applications requiring rapid bacterial quantification.
