INTRODUCTION
This amplifier system and the sensors associated with it are designed to detect and
amplify perfusate pressures, temperature and ECG signals or surface potentials from
isolated perfused heart (Langendorff) and working heart (Neely) preparations. The
system can also be used to measure perfusion pressure and temperature from other
isolated organs, like kidney, liver and mesentery. In-vivo measurements of blood
pressures, temperature and ECG from animals can also be performed using this
system.
The modules in this amplifier system do not have selectable gain and filter controls,
because they are designed to work with data acquisition systems that have circuitry
and software for amplifying and filtering recorded data. If you require more
information about this amplifier and data recording systems that are capable of
working with this amplifier, contact WPI at sales@wpiinc.com or 941.371.1003.
