A spool of 7.62m (25 ft) PFA-coated silver wire, which can be used for microelectrode fabrication for a variety of electrophysiological applications, including recording potentials in isolated tissue and organs, such as the isolated heart. The wire is 99.99% pure silver and has a nominal American Wire Gauge (AWG) of 32 for the bare silver wire, and 30 with the coating. The bare diameter is 203.2 µm (0.008”) and the coated diameter is 279.4 µm (0.11”).
- For the bare wire outer diameter = ± 2.54 µm (0.0001")
- For coating thickness from 25.4 µm to 31.75 µm = ± 12.7 µm (0.0005")
- For coating thickness from 38.1 µm to 50.8 µm = ± 25.4 µm (0.001")
- For coating thickness from 50.8 µm to 63.5 µm = ± 50.8 µm (0.002")
Therefore total wire tolerances = bare wire outer diameter tolerance + 2x coating thickness tolerance.
