Silicone Heating Pads

Following on from a thread I saw on another post

Does anyone think these pads could be used with yeast production? namely on a wobble plate or even a stirrer to create your very own heated device? Question is would these silicone heated sheets interfere with the magnetic field?

What temperature do they run at mate?

They have all sorts of voltages, temperature ratings and current densities for jobs big and small. Not just made of silicone either.

Omega is one of the big global makers. See http://www.omega.com...mp;book=Heaters

(Check out the 'Technical Reference' link at the bottom of the left-hand side-bar, then scroll down to the section called 'Temperature Related'. Some useful info there on how flexible heaters work and how to apply them to applications)

Cheers for the link, I'll have a read through http://www.omega.com/prodinfo/flexibleheaters.html

My initial thoughts were this, there are numerous commercial ceramic style heated stirrer plates available most of which seem to rely on some sort of temperature probe & the range of temps seems to be quite high, far more than is needed for yeast management.
So a very low wattage silicone pad might be the ideal DIY solution (dependant on calculation) & could be retro fitted to any device or as another person as mentioned even directly to a flask (not too sure of the cleaning / sticking implications that might impose?)
