Disposable Tungsten Electrodes are constructed of high quality tungsten wire for superior shape and integrity throughout the excision procedure, making them ideal for hospital and clinics. Disposable Tungsten Electrodes feature molded safety grip insulators combining patient safety with easy insertion into and removal from a surgical penlight. The Tungsten Electrodes use a standard 3/32″ (2.3mm) shaft for added convenience and are compatible with mostly electrosurgical generators.
