1. GLS80 250/500/1000mL bottles and 0.4L Tall Form beaker as standard vessels 2. US Pat. 8,162,295 ambient gas exchange means (aGEM) standard in all vessels 3. aGEM patent provides very low vvm (0.01-0.2) aeration without connecting to line air 4. hence O2 and CO2 partial pressures in jar mimic those in a large volume production fermentor 5. high vortex pumping/mixing of low to medium shear mimic axial pumping (zone2) in a large fermentor
