Spin Coater System (Original Design)
This was my attempt to build a low cost spin-coater system.
For about $70.00
dollars in parts and some ingenuity (and ofcourse access to the college's machine
shop), I was able to put together the
system shown below. Ironically, we latter purchased a
commercial
spin-coater for $5000.00, but I saw little difference in the sample
prepared using the one I built. In my opinion, the only
reason to buy one of those things is to get better control of the
overall spinning process which is needed by some
applications. However, most people just need
something that goes around fast, and holds a small sample for
R&D work.
