Fisher Scientific 14-386-101E Hollow Cathode Tube

The Fisher Scientific 14-386-101E Hollow Cathode Tube is a hollow cathode assembly featuring an iron (Fe) cathode and neon (Ne) fill gas. This component is designed as a light-source element for analytical instruments that operate with hollow cathode technology, providing a controlled discharge when energized. Verified details identify the cathode material as Fe and the fill gas as Ne, with Fisher Scientific listed as the manufacturer and 14-386-101E as the part number. Use of this hollow cathode tube is typically associated with laboratory systems that require an Fe-based hollow cathode discharge, and the 14-386-101E designation ensures the correct replacement part for compatible equipment. When sourcing spares, this part should be matched to equipment that specifies the 14-386-101E hollow cathode tube to maintain instrument performance and continuity of analytical workflows.
