The development and evaluation of a 6‐hours laboratory class, based on capillary electrophoresis (CE) and the detection of microbial contaminants, is described. It can be easily scaled up or down, to suit class sizes up to 188 and completed in a shorter time scale. CE uses narrow‐bore fused‐silica capillaries to separate a complex array of large and small molecules. A laboratory exercise has been devised to illustrate how CE‐based genetic analysis system processes DNA fragment analysis to detect three microbial contaminants. The protocol is relatively inexpensive and uses standard molecular biology reagents and equipment. © 2018 by The International Union of Biochemistry and Molecular Biology, 46(3):279–284, 2018.
