Based on over thirty years of personal experience in the field, we have tried to analyze what is necessary for efficient, modern bioreactors and select the best technical solutions, which would lead to best performance. We have invested a major effort to make our bioreactors more efficient and to provide them with the best parameters. This required new ideas and many innovations. The result is much simple and better laboratory fermentor/bioreactor system. The results obtained show that we have many reasons to believe in innovations!
