Standard Luggin Tube

This is a Luggin Tube designed for use with our Standard Volume Cells and Standard Size Reference Electrodes, as well as most cells that have a 14/20 taper port.  The Luggin Tube (also called a Luggin capillary) is often used to direct the conductive path between working and reference electrode to minimize uncompensated resistance (iR drop), which unless corrected, can skew electrochemical data.  Adding sufficient (100 mM or higher) supporting electrolyte is often the easiest method available of avoiding high iR drop, thereby making the Luggin Tube unnecessary; however, it is not always possible to simply increase the concentration of electrolyte for a variety of reasons.  The 1 mm ID tip (opening) is angled and directed horizontally toward the center of the cell where a working electrode is typically positioned (e.g., rotating disk or rotating ring-disk electrode).
