Heating a cuvette which is placed in a box.

[Prem Arjun]

Hello everyone.

I need some ideas/Inputs on heating a cuvette(upto 60° C). And the temperature should not exceeding 80° C,Since the trasistion temperature is 80° C). This cuvette is inserted into a rectangular box(L:8cm;W:3cm;H:2cm). So space is an important constraint here.

What I am thinking is to have a copper plate under the cuvette and use the resistor heating(If you have any other ideas of heating please share it). But I do not have any idea on how to control the temperature.

Please let me know if you have any ideas on controlling the tempeartures.

Thank you.

You might want to use aluminum instead of copper.
Aluminum is less expensive, easier to machine and the thermal conductivity is not significantly different from copper.

try a simple mechanical switch to open when it gets too hot, and close when it gets cold, like this
