What should I look for in a college chemistry lab?

TOYS! Instruments of all kinds Gas

Chromatograph, Liquid Chromatograph, Spectrometers, Mass Spectrometers (very nice), NMR, and biotechnology equipment such as electrophoresis chambers

Minimum digital balances, analytical balances, a few computers running up to date software, and some spectrometer like UV-vis or UV-IR.
