    In the production process of cell therapy preparations, there exists a critical and fatal problem: the content of residual chlorine in sterile water. Don't underestimate this tiny amount of residual chlorine. If the residual chlorine in sterile water exceeds 0.01mg/L, it can lead to cell death. It's like planting a time - bomb in the cells' living environment. Now, let the chlorine sensor Manufacturer, Meideshi, give you a detailed explanation!

    Traditional detection methods involve conducting tests once a week. This is like using a thermometer to detect viruses, unable to discover potential hidden dangers in a timely manner. Cell growth is a continuous process, and the content of residual chlorine may change at any time. Testing only once a week means that the residual chlorine may have already exceeded the standard within that week, while the enterprise remains unaware.

    There was once a pharmaceutical company that failed to detect the excessive residual chlorine in sterile water in time, resulting in the mass death of cells and the halt of the entire production process. Statistics show that due to the problem of excessive residual chlorine, some pharmaceutical companies suffer losses of up to hundreds of thousands of dollars in cell culture every year. This not only wastes a large amount of resources but also seriously affects the R & D progress of preparations.

    Peer Comparison: A Turnaround Brought by Successful Cases

    A CAR - T enterprise successfully solved this problem. They introduced an online residual chlorine detector, which is like a “residual chlorine microscope” capable of monitoring the concentration of residual chlorine in sterile water in real - time.

    Once the residual chlorine concentration exceeds 0.005mg/L, the instrument immediately issues an alarm and automatically switches to the standby water source. Since using this detector, the cell survival rate of the enterprise has been significantly improved, soaring from the original 70% to 95%. This huge change has amazed their peers, who have begun to pay attention to the application of online residual chlorine detectors.

    The Value of Online Water Quality Automatic Detectors: 24 - Hour Protection for Cells

    The core function of a Digital residual chlorine sensor is crucial. It can monitor the concentration of residual chlorine in sterile water 24 hours a day, like an indefatigable guardian, constantly protecting the safety of cells.

    By presetting precise early - warning thresholds, it can issue an alarm before the residual chlorine content reaches a dangerous level, avoiding the lag caused by “periodic detection”. It's like sounding an alarm before danger arrives, giving the enterprise enough time to take measures. With this detector, a solid “safety shield” is built for the cells, completely eliminating the risks caused by residual chlorine toxicity.

    Corporate Action Points: Moving Towards Active and Precise Control of Residual Chlorine

    For pharmaceutical companies, introducing an online residual chlorine detector is of great practical significance. It enables enterprises to shift from the helpless mode of “passively testing and changing culture media” to the active mode of “actively and precisely controlling residual chlorine”.

    By actively and precisely controlling the residual chlorine content, enterprises can ensure the stability of cell survival and reduce losses during the production process. They no longer need to frequently change culture media due to cell death, saving a large amount of time and cost. This helps with the R & D and clinical advancement of preparations, making enterprises more competitive in the field of cell therapy preparations.

    If your enterprise is also troubled by the residual chlorine problem in the production of cell therapy preparations, feel free to consult Meideshi, a chlorine sensor Manufacturer. Let the cells grow in a safe environment and lay a solid foundation for your enterprise's development.
