DetailsOEMCS is a small scale system for cultivating bacteria under normal conditions. It is a replacement of shaker flasks to grow seed cultures or to prepare biomass for small scale DNA extractions. The device is designed to maximize the gas exchange between the air and the culture to ensure the bacterial cells in the culture sufficient supply of oxygen. Bacterial cells breath happily in the culture and grow fast. Using OEMCS is simple and the unit is easy to be cleaned.
