View Full Version : Needed: 40AWG insulated copped wire for Fine Wire electrodes

05-19-2011, 01:43 PM

I am looking for a small gauge wire (40AWG) to make fine wire electrodes for a study I am currently working on. I would prefer an insulated copper wire, with silver being a second choice (something with minimal resistance). If anyone has this product lying around and willing to sell or has a contact for where you can order it from, it'd be greatly appreciated.

Thanks :)

Hi Steph,

Try New England Wire Technologies. http://www.newenglandwire.com/index.asp

They fabricate all kinds of wire and cable, including very fine diameter insulated copper wire.

In the USA fine wire can be purchased from:

California Fine Wire (http://www.calfinewire.com)
P.O. Box 446, Grover Beach, CA 93483-0446
Tel: (805) 489-5144 - Email: custservice@calfinewire.com

However, there are some potential issues with both copper and silver wire in this usage - I assume you're doing animal research and not inserting the wire into humans?

We sell ready made, sterilized, fine wire electrodes (30mm and 50mm lengths) for use with human subjects - the web page http://www.motion-labs.com/prod_access_finewire.html has details of their construction and there's a lot of good information about fine-wire issues in previous posts on Biomch-L.
