The Pressure Myograph System - 114PN has less optional features while still allowing experiments on pressurized small arteries, veins, and other vessels. This specific model is for researchers who want to design their pressure and flow studies without measuring the longitudinal force. A small, intact segment of an artery or vein is mounted onto two small glass cannulas and pressurized to a suitable transmural pressure. The near-physiological conditions permit the investigation of myogenic responses and flow-mediated dilation in response to pharmacological agents and other vasoactive compounds.

The force transducer and third positioning micrometer have been removed from the 114PN, making this system more economical. All other features and benefits from the 114P Pressure Myograph System have been included. A built-in heating system maintains the chamber temperature, eliminating the need for continuous and often costly superfusion. The chamber cover includes ports for superfusion, rapid draining and filling, cumulative addition of drugs, and oxygenation. To facilitate cleaning, the chamber is made of acid-resistant stainless steel. 

The state-of-the-art Pressure Myograph software MyoVIEW will collect data such as vessel wall thickness, changes in vessel and lumen diameter, intravascular pressure, and a host of other calculated parameters, such as shear stress and vascular resistance, setting pressure or perfusion myography apart from standard organ bath techniques. 

As an option, the FlowMeter - 162FM can be added to the system to measure flow between 15-4000μl/min.
