(After selecting the desired Tip Profile for your application, click on a metal type below to view electrode selections and pricing)

 A - Standard Tip Profile - (25:1 taper)
 Tungsten - Platinum/Iridium -  Stainless Steel

 H - Heat Treated Tapered Tip Trofile -(25:1 taper)
  Tungsten -  Platinum/Iridium -  Stainless Steel

  F - Extra Fine Tip Profile - (50:1taper)
  Tungsten only

 B -Blunted Tip Profile -(25:1 Taper)
   Tungsten-  Platinum/Iridium -  Stainless Steel

The following electrodes are excellent for bipolar stimulation studies where the current injection needs to be confined to a small localized part of the neural tissue. Stereotrodes have also been used for enhanced isolation of single neural elements by simultaneous recordings of multiple units on two closely spaced microelectrodes. The tip spacing is typically equal to the diameter of the electrode shaft, however, they can be specified to greater separations in most instances

The above graph and metal selection guide will allow you to select one of four available tip profiles and the metal type most appropriate for your application.
