John Kempf, microbiologist and instructor, explaining to the students how to prep water samples for microbial analysis. Earlene Erbe, chemist and instructor, explaining good laboratory practices and demonstrating proper pipetting techniques to students preparing water samples for pesticide analysis by enzyme immunoassay.
