Subject: [Histonet] Source for ultra low temperature immersion thermometer

Good Morning Histolanders,

Does anyone have a source for an immersion thermometer that can be used to measure the temperature of the isopentane or 2-methylbutane or methylbutane ( you choose) ;-) used for freezing muscle biopsies?

I have searched using Dr. Google and cannot find one that goes below -100 degrees C.

Thank you in advance.
