In the process of looking for used equipment to put together a small
microbiology lab I have come across a lot of interesting stuff.  Items
like incubators, centrifuges, vortexers, micropipetters as well as
very sophisticated diagnostic equipment.  I've also come across large 
environmental test chambers and even a scanning electron microscope. 
Many of these items were new surplus while many others were used but
still in very good shape.  I think most items were acquired from 
liquidations.    

What surprised me was that most of these items will eventually
be scrapped and are in effect worthless.  Is this because labs
in general have plenty of money for new equipment or is it 
cheaper in the long run to buy new equipment under warranty?
Please clear up the mystery for me.
