Bioreactor Vessels Compatible with Sartorius Biostat B Bioreactor Control Units

The United States Department of Agriculture (USDA), Agricultural Research Service (ARS), is conducting market research for bioreactor vessels compatible with Sartorius Biostat-B Bioreactor control units. The required vessels must have specific features, including compatibility with current Biostat-B Twin MO bioreactor control units, stirring mechanism, and water-based temperature control. The vessels should also have connections for double wall UniVessel Glass, a stainless steel head plate with various ports, and a stainless steel stirrer shaft with direct coupling to the Biostat-B Twin MO bioreactor control unit motor. * The vessels must be 2-liter autoclavable glass vessels. * The vessels must be compatible with Sartorius Biostat-B Bioreactor control units. * The vessels must have a stainless steel head plate with ports for temperature probe, oxygen sensor, pH sensor, acid/base/anti-foam and feed additions, anti-foam sensor, water chilled condenser, and aeration sparge. * The vessels must have a stainless steel stirrer shaft with direct coupling to the Biostat-B Twin MO bioreactor control unit motor. * The inner dimensions of the vessels must be Diameter = 130mm, Height = 240mm.
