I'm a physician doing benchtop experimentation. Background: Tissue is known to coagulate at 43 degrees celsius (CEM 43 thermal tissue damage index).
I'm seeking to find/build a temperature controlled heating device to induce various thermal injuries in explanted (ex vivo) tissue. I'll be measuring those changes at the surface level of the tissue using a fiberoptic temperature probe.
Specifically, I need the device to accurately generate heat (40-80 deg Celsius w/ increments of 1 degree celsius). Any ideas? I've explored modifying a soldering iron and heating up metal in water bath to specific temps.
Thanks in advance!
