LF-01 AND LF-02 LANGENDORFF PERFUSION SYSTEMS
The basic configuration is comprised of two double-wall glass columns with built-in oxygenation and pressure control capability. The thermostated glass spiral features three 3-way taps for connection to the double-wall columns, an optional constant-flow module, and the perfusion canule. The heart suspending unit is equipped with connections for buffer flow, water jacket, sensors and drug administration. The loss of physiological saline is (re)introduced into the system by means of a roller pump. The level of constant pressure is set by positioning the height of a glass column within the double-wall, thermostated main column(s). Constant coronary flow is maintained by a precision roller pump.
