30.5 m (100 ft) Spools:
Tetrode Wire PtIr 18 um & NiCr 25 um will no longer be available once stock is depleted.
Neuralynx will not continue to stock tetrode wire spools due to quality issues. We recommend ordering direct from California Fine Wire or other supplier with diameter range of 10-25 microns.
If using our Tetrode Assembly Station, make sure your spool is 85.5 mm max in length with a hole diameter of 16-23 mm, and an overall diameter of 57-63 mm. This will allow for a proper fit with respect to the wire spools and the Tetrode Assembly Station.
