Why waste time and wait 5 days to assess the microbiological quality of Purified Water when you can respond within an hour? Enhance safety and mitigate risks by avoiding inaccurate measurements and increasing testing frequency.
Recognize the risk of pathogen growth earlier. Start sanitization in line with requirements. Prove their efficiency instantly afterwards.
It is now the time for more accurate and faster processes to determine bacteria levels in water. BWT recommends flow cytometry.
Reliable and accurate counting of all cells, not just colonies
It is simple, intuitive, and user-friendly
Simple data transfer for system integration into SPS
Integration in the ultra-pure media system or manual sampling
Results and reaction if required in < 1 hour
About CFU as the ultimate benchmark
CFU remains the key variable in assessing microbiological quality. However, even the pharmacopeia criticize the validity of this method.
The USP considers the CFU value to be more of an estimate than an exact figure as, for example, only 0.1–1% of all germs are counted as CFU in potable water. As a result, it is posited that CFU should not be considered the only measure for assessing microbiological quality.
According to Ph. Eur., the applicable threshold values were established without quantitative measurement. As an example, the—randomly—determined acceptable value of 10 CFU / 100 mL for WFI has become the norm.
It can be seen: even the pharmacopeia clearly see the weaknesses and limits of conventional methods of measuring CFU. For this reason, it is now time to use cutting-edge technologies that can offer game-changing advantages to quality managers and microbiologists.
