​Dual-Channel Wire Myograph System – 420A

The Dual Wire Myograph System allows you to examine vascular reactivity and functional responses on small isolated arteries. Model 420A is ideal for testing two vessels with diameters of 30 μm simultaneously – 3 mm, independently. The vessels are mounted as ring preparations by threading them over two parallel wires and securing the wires to two supports or “jaws.” One support is attached to a precision micrometer, allowing manual control of vessel circumference and stretch. The other support is attached to a force transducer for the measurement of force/tension development.
