In the Laboratory
A Simple, Transparent Fume Hood
John Fredericks
Dallas High School, P. O. Box 2000, Dallas, PA 18612
Cover
October 1998
Vol. 75 No. 10
p. 1299
Abstract
An inexpensive transparent fume hood can be constructed from a clear-plastic two-liter soft drink bottle that is cut just above the base. A length of vacuum tubing is secured to the opening of the bottle using black electrical tape. The tubing is then connected to a water aspirator. Beakers or flasks easily fit inside the bottle, and the bottle may be secured with a clamp and ring stand for added stability. This device has been used to collect the noxious NO2 gas generated from the reaction of copper metal with nitric acid. It also may be used in the collection of other gases. It should not be used to collect gases that are not water-soluble or in experiments that involve open flames.
