A Chemical-Stop Rapid Flow Apparatus

Abstract
A rapid flow apparatus with multiple mixers is described, capable of measuring reaction times of 0.008 to 0.5 sec. The solution‐containing parts are of Teflon and Lucite to minimize metal contamination. A rack and pinion drive, using an electric clutch, is described, along with a positive assay valve needed when the apparatus is used as a chemical‐stop flow apparatus.
