The present invention relates to processes for making anodes suitable for use in the production of titanium metals. The test adapter consists of a printed wiring board having at least one electrically conductive path and at least one connection terminal in electrical communication with the conductive path, whereby the connection terminal connects the UUT to the adapter. Upon deployment from the outer cannula, the needle cannula substantially returns to the preformed configuration for the introduction or extraction of materials at areas lateral to the entry path of the needle assembly.
