EGL electrodes have consistently raised the industry standards for reliability and performance since their introduction in 1930. To ensure rigid quality control, all phases of manufacturing are performed in-house, including emission coating, inverter welding shells with lead wires and sealing and centering the mounts in glass envelopes.

• Heavier gauge, solid nickel, corrosion-proof, seven-strand lead wires
• Thicker tubulation wall for easier, stronger tip-offs
• Stronger inner lead wires keep shell centered in tube, reducing vibration
• State-of-the-art inverter welding provides superior shell support and conductivity
• After forming, shells receive pro-prietary nickel plating for more uniform, non-porous coverage
• Electrodes are fully annealed to relieve stress, preventing cracking
• Thicker shell walls heat up evenly, eliminating hot spots, promoting uniform conversion of emission coating
• Newly developed emission coating measured precisely for each shell, ensuring that all shells "come up" evenly during bombardment
• Patented ceramic collar centers shell in tube, eliminating side ignition, sputtering and blackening
