MCL-II: MicroLab's Compact Laboratory

 

 

 

 

 

 

 

 

 

Carl Sagan once said, "At least part of the time, Science should be taught as it is practiced". With MCL units, students formulate their questions, design their experiments, rapidly collect their data, and analyze it right in the lab.

Students using MicroLab stay most of the lab period because they can evaluate their results with their instructor present to help. If necessary, they can revise their strategy and run the experiment again. Both proof-of-concept and inquiry experiments are carried through to their conclusion in the lab.

Departments can justify lab hours to their administration by demonstrating constructive use of time and student involvement in both the active and thought-intensive processes of science.

In addition to general purpose sensor measurements such as temperature, pressure and pH, instrument programs are provided for spectrophotometry, kinetics, fluorescence, electrochemistry, turbidity and gas chromatography. Data can be analyzed with MicroLab's integrated graphical analysis software, or saved directly to an optional EXCEL spreadsheet.

Additional factors are safety and chemical cost. High resolution data and resulting small sample size mean increased safety, lower supply and disposal costs, and little need for expensive fume hood facilities.
