Dear all,
As a finer point to the discussion of stage/microscope heater systems, can
folks give me an idea of where to find just a heater and thermostat
controller for an existing enclosure?  I have searched high and low for a
recently mentioned heater for incubating eggs, and have come up
empty-handed.  Everything I've seen comes as complete units, so components
are not mentioned.  The presumption is that once the desired tempurature is
reached, it can be maintained within ± 0.5 degrees or less.

Thanks very much,
Carl

Dear Carl,
We built one (actually I asked someone else to build it) using a  
proportional controller (Omega CN370, $225).  The actual heater is  
the element from a hair dryer mounted in 3" PVC sewer pipe lined with  
kaolin batting.  A salvaged 3" computer fan provides the flow.  A  
rectifier was added that can be switched in and out of the power  
circuit to control how much heat is generated.  A thermistor to the  
PID controller provides feedback to the controller.    Its been  
working for about 4 years now, with light use.

Hope this helps.

We have been using WPI one for a year now and happy with it.

Good luck!

Dear Carl,

If a heating controler performs to your specs will depend on the material, shape, volume and architecture of your incubator (and the ambient conditions) maybe that's why its difficult to buy a stand alone solution, because no serious manufacturer would like (and be able) to grant you the thing is working in the end.

In case you would provide the above mentioned information and the microscope type, I have no doubt folks at embl Heidelberg (embl-em.de) would provide you with their heating unit, which maintaines temp to +-0.1degC between 16 and 42 degC, provided ambient temp between 19 and 24 degC.
Of course +-0.5degC might be achievable with a lower cost solution, though be aware you will observe focus shifts with 0.5degC variations at least with >1.2 NA lenses.

Hope that helps.

regards, jens
