Used to control the flow of biological liquids in Langendorff or other isolated perfused organ experiments, by controlling the speed of the peristaltic pump. It can be used to provide average constant perfusion flow or pressure.
The STH Pump Controller connects to a Bridge Amp and Pressure Transducer and uses a negative feed-back control circuit to alter a flow rate signal sent to a Peristaltic Pump. Therefore a constant perfusion pressure can be maintained in the perfusate line, typically within ±1 mmHg. It can also be set to a fixed flow signal manually, when working under constant perfusion flow conditions. The flow rate and pressure signals are monitored, displayed and recorded with a PowerLab system and LabChart software.
The STH Pump Controller is supplied with:
The STH Pump is included as part of this Langendorff System.
