The KT suffix refers to Kapton™ cladding. All Metal Microelectrodes are available in custom lengths, blunt or heat treaded (extra charge). Ordering: microelectrodes available Add the B suffix where blunt electrodes are desired. (For example, an IRM123A10KT ordered as a blunt will be IRM123A10KTB.) Add the H suffix where heat treated electrodes are desired. (For example, an IRM123A10KT ordered as with heat treatment will be IRM123A10KTH.) on website Additional metal www.wpiinc.com UK: Tel: +44 (0)1462 424700 • wpiuk@wpi-europe.com World Precision Instruments www.wpiinc.com Germany: Tel: +49 (0)30-6188845 • wpide@wpi-europe.com US: Tel: 941-371-1003 • sales@wpiinc.com 105
