The STH Pump Controller is a constant flow or constant pressure controller for a peristaltic pump and is used to control the flow of biological liquids in
Langendorff or other
isolated perfused organ experiments. The STH Pump is included as part of the ADInstruments
Langendorff System.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 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 flow conditions. The flow rate and pressure signals are monitored, displayed and recorded with a PowerLab system and LabChart software.
Hardware: The STH pump will only function with PowerLab data acquisition units and therefore is not suitable for use with other data acquisition systems.
