The Distek BiOne 1250 is a laboratory instrument that controls bioprocess reactions in both mammalian and microbial models used in research and development for things like vaccine and pharmaceutical development. The actual reaction takes place in the accompanying vessel where variables such as temperature, pH, air composition and agitation rate are varied to achieve the desired outcome. The BiOne incorporates a series of OEM rotometers or optional gas flow modules to meter gasses as well as one or two banks of OEM peristaltic pumps to meter base or acid solutions into the reaction. All processes are programmed and adjusted via a touch screen interface.
