Mini Fermenter
High School
Undergraduate
Investigation
This mini fermenter can be used to conduct small-scale fermentation investigations or demonstrations similar to research done by GLBRC scientists. The design allows for students to use simple techniques and classroom-grade probes to collect data during fermentation on a range of variables, such as ethanol concentration, CO2 production, temperature and pH. The complete mini fermenter can be built with readily-available supplies for approximately $20 (detailed supplies list included with instructions).
