Tungsten Wire (30 um diameter / 1m length)
This wire can be used in wire myographs, where a thin wire is passed through the lumen of a microvessel ring preparation on each side. The wire serves to restrain the vessel ring segment to the jaws of a wire myograph apparatus.
Choose a wire diameter based on the inner diameter of the vessels you work with, keeping in mind that you need to pass two wires through the lumen of the microvessel. Select the smallest diameter wire that you can comfortably work with to minimize risk of damaging the vessel lumen/endothelium.
