Dr. Richmond recommended using non-flammable and non-explosive Novec (tm) Engineered Fluid HFE-7100. We are currently using this for our freezing and it works very well. The main thing we have noticed is the blocks float in it and do not sink as they would with other solvents.
It is a 3M product, and my contact there last year was ebin...@mmm.com (Erin Binder).
