spectronic 20

I use Spec 20D's in Cell Biology.  The D is for digital.  I've found
quite tough and reliable.  The digital readout is easy for students to 
understand and read, although getting the blank to exactly 0 drives them 
nuts.  They look nicer in the business gray with the angles compared to
old  Caucasian-flesh-colored curvy things (my subjective opinion).

Watch out what wavelengths you want to use.  We measure a lot of 
absorbances at long wavelengths (500-600), and you need to be sure to
special filters for that.

Also, be careful when mixing spectrophotometers.  Every semester it
someone will stick a square cuvette into Spec-20D's round hole.
