Hello,

I am familiar with Sigma Systems Corporation's C4 model - very good hot plate
with digital control, but maybe expensive.  You would need liquid nitrogen in
order to control the cooling.  There are different sizes of plates available
from this company.

Good luck!

Subject: [mems-talk] hot plate recommendation

Hello all,

I'm looking to purchase a programmable hot plate for our lab to do baking of
photoresists for photolithography. I'm looking for one where I can control the
ramp of heating and cooling (i.e. tell it to increase its temperature at 2 C/min
then stay at some temp for a while and then cool at 1 C/min). If anyone could
recommend a brand or model to me I would greatly appreciate it.
