Pilot Scale Bioreactors

We offer stainless steel bioreactors from 20 to 15000 liters, as well as bioreactor lines, including other technological vessels. An autonomous bioreactor consists of 3 main parts:
Bioreactor vessel;
Technological stand;
Control cabinet, including PLC.
The connections between the bioreactor vessel and the technological stand are implemented with the help of flexible parallel wrapped stainless steel tubes.
To ensure fully automated in-situ sterilization process, it is necessary to install pneumatically controlled membrane valves in the bottom, the inlet of a sparger and the lid of the vessel.
The bioreactor vessel
The fully equipped stainless steel bioreactor vessel (sterilizable in place) with upper or lower magnetic drive for agitation with 2 – 3 standard rushton turbines (pitched blade or marine mixer optionally). For all vessels H:D is in the range of 1:1.5 to 1:3. It can be specified in certain limiting sizes. For all vessels the maximal design pressure inside the vessels – 3.0 bar, in jacket – 3.5 bar. Maximal temperature – 1400C. Inner vessel wall: surface roughness lower than 0.4µm.
Outer vessel wall: surface roughness – 0.63 µm (pickled & passivated).
The material of the parts, contacting with product is stainless steel 316L. For parts, not contacting with product (for example, jacket), – stainless steel 304. All bioreactors have insulation over the jacket. The outside surface of insulation is covered by stainless steel 304.
