The Radnoti Langendorff Constant Flow Non-recirculating apparatus permits the researcher to create a constant flow non re-circulating Langendorff preparation for Rat as well as Guinea Pig or Small Rabbit.  With additional equipment left ventricular pressure, apical force using the built-in pulley system and coronary resistance can be measured.

The system uses a water-jacketed 2-liter reservoir to maintain and gas the perfusion solution or buffer. A peristaltic pump draws from the reservoir and drives the solution up to a water-jacketed bubble trap via a water jacketed flex tube assembly, where bubbles are removed from the flow, and then down to the aortic cannula into the heart chamber via another water jacketed flex tube assembly. Effluent from the heart is directed to waste or collected.
