The Teflon Insulated Silver Wire (7.5 m) can be used for recording potentials in isolated tissue including the isolated heart or other electrophysiological applications. The silver wire has a 99.99% purity and a nominal American Wire Gauge (AWG) of 32 for the bare silver wire and 30 including the insulation. The "bare diameter" is 200 µm and the "coated diameter" is 280 µm.
- For the bare wires = ± 1.27µm
- For insulation thickness from 25.4 µm to 31.75 µm = ±12.7 µm
- For insulation thickness from 38.1 µm to 50.8 µm = ± 25.4 µm
- For insulation thickness from 50.8 µm to 63.5 µm = ± 50.8 µm
Therefore total insulated diameter tolerances = bare wire tolerance + 2x insulation thickness tolerance
