Sartorius Stedim 884719-080310 Heat Exchanger for 1-5 L Bioreactor 1in Headplate Port

The Sartorius Stedim 884719-080310 is a specialized immersion heat exchanger, often referred to as a "cold finger" or cooling loop, designed for precise temperature regulation within benchtop bioreactors ranging from 1 to 5 liters. This component is engineered to be inserted directly into the culture vessel through a standard 1-inch (approx. 25 mm) port on the headplate, extending 21.5 cm into the media to ensure effective heat transfer.

Constructed from high-grade 316L stainless steel, this heat exchanger is crucial for processes where metabolic activity generates significant heat that must be removed to maintain optimal cell growth or fermentation conditions. It operates by circulating a cooling fluid (such as chilled water) through its internal loop, absorbing excess thermal energy from the culture fluid. Additionally, its vertical presence within the vessel often serves a secondary function as a baffle, helping to disrupt the vortex created by the impeller and improving overall mixing and oxygen transfer within the reactor.
