Safety enclosure for mercury filled McLeod gauge

Abstract

The enclosure presented both protects the gauge and contains the mercury if breakage should occur.

An Accessible Mercury-Free Vacuum Schlenk Line for Air-Free Techniques

“…The impetus for this contribution is the increased attention to the hazards of mercury in the laboratory. This Journal has published articles that describe the use of the mercury bubbler to introduce inert gases to reactions that must be protected from the atmosphere, and safety notes to provide ways to eliminate or protect the lab from mercury in thermometers and McLeod gauges. − Our institution has initiated a mercury reduction policy. The driving force for this policy, The Great Lakes Binational Toxics Strategy, signed by Canada and the United States in April 1997, set a goal of virtual elimination of mercury with significant measurable results by 2006, and it is a policy that continues to be implemented .…”
