    • A two chamber system with fill gas in one chamber and vacuum in the other provides a means of burning in one or more vacuum tubes while avoiding contamination from environmental gases. Vacuum tubes are often burned in after being sealed. Some processes burn-in the tubes before sealing them. The burn in process can take days and provide ample opportunity for environmental gases to contaminate the vacuum tube. The vacuum tube's fill tube passes through the vacuum chamber and into the fill gas chamber. Environmental gases leaking past the fill tube are evacuated by the vacuum. Similarly, fill gas leaking past the fill tube is also evacuated to vacuum. As such, the environmental gases are drawn away before contaminating the vacuum tube.
    • 具有一个室中的填充气体和另一个室中的真空的两室系统提供在一个或多个真空管中燃烧的装置,同时避免环境气体的污染。 真空管经常在密封后燃烧。 一些过程在密封它们之前烧坏管。 燃烧过程可能需要几天时间,为环境气体提供充足的机会污染真空管。 真空管的填充管通过真空室并进入填充气室。 通过填充管泄漏的环境气体被真空抽真空。 类似地,通过填充管泄漏的填充气体也被抽真空。 因此,在污染真空管之前,环境气体被抽走。
