舒伦克瓶（英语：Schlenk flask），也称舒仑克管（英语：Schlenk tube），是一种由德国化学家威廉·舒仑克发明的可用于需要隔绝空气的化学反应的反应器皿。

A Schlenk flask, or Schlenk tube is a reaction vessel typically used in air-sensitive chemistry, invented by Wilhelm Schlenk. It has a side arm fitted with a PTFE or ground glass stopcock, which allows the vessel to be evacuated or filled with gases (usually inert gases like nitrogen or argon). These flasks are often connected to Schlenk lines, which allow both operations to be done easily.
