Practicing Aseptic Technique with Microbial Cultures

Working with bacterial cultures educates students in differences in bacterial shape, composition and incubation temperature. All bacterial cultures sold by Flinn Scientific® are nonpathogenic. However, it is extremely important to always practice aseptic technique to avoid culturing unwanted microorganisms obtained from the environment.

Gram Stain Determination

Bacteria can be classified according to the results of a procedure known as a Gram stain. Gram staining is often the first step in identifying an unknown bacterial species. The Gram staining technique requires relatively few reagents, is well defined, and can be successfully practiced with a few simple steps.
