  • Description

MyoHEART Langendorff system - 900MH

With build-in pressure transducers, pressure is easily monitored during experiments on constant flow mode. Under constant pressure, coronary flow may easily be measured with an add-on flowmeter.

Depending on configuration the MyoHEART monitors aortic flow, pH level (perfusion buffer), pO2 level (perfusion buffer), and heart surface temperature. Controllable parameters are perfusion pressure, flow, temperature, reservoir temperature, BPM (pacer) and iso-volumetric left ventricular pressure.

Record and display of up to 18 traces are easily done using LabChart by ADInstruments. Using the DMT Device Enabler the MyoHEART system streams data directly into LabChart.
