A Simple, Inexpensive, Mercury-Free Bubbler Apparatus

Abstract

Inert gas manifolds for the handling of air-sensitive materials are commonplace in the inorganic chemistry curriculum as well as in research laboratories specializing in inorganic and organometallic synthesis. Mercury bubblers are ubiquitously implemented for maintaining a positive internal pressure for air-free manifold systems, commonly known as Schlenk lines. This has rendered them difficult to replace with equivalent and accessible alternatives. This communication describes the setup and implementation of a simple, inexpensive alternative to the traditional mercury bubbler that is modular and flexible enough to fit most any laboratory space.

“…One adapter is connected to a simple oil bubbler for releasing pressure and the other is to connect a vacuum/inert gas manifold system (Schlenk line). This setup (Figure 2) has been successfully used in conjunction with our previously reported Hg-free bubbler system 36 to provide a sufficient "overpressure" during normal purge−refill cycles as well as during solids additions.…”
