Laboratory 1945-1965
Fluorescent lighting
Glassware and instruments are more compact
Still prefer wooden furniture but some metal and plastic is used

Laboratory space 1965-1985
Most modern equipment is present
Computers are still not present or are too big for the lab
Instruments are still not as visible
Not as much ventilation but some safety equipment

1985-1995
Computers present
Instruments present
Digital balances
Ventilation and safety devices in plenty
Much area for electronics to plug in

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.
