👉 Jar fluid, also known as Jarvis fluid or Ether Jar fluid, is a volatile organic compound historically used in early computing and electronics for various purposes. It was primarily composed of ether, with other components like benzene or toluene, and served as a coolant and insulating medium in vacuum tubes, relays, and other electronic components. Jar fluid's low boiling point allowed it to absorb heat efficiently, preventing overheating and damage to sensitive electronics. However, its flammability and toxicity made it hazardous, leading to its replacement by safer alternatives like mineral oil and silicone-based fluids in modern electronics.
