For making frozen sections, I wonder whether could  I pre-freeze isopentane in a -70C fridge,and then snap freeze the specimen in it?

 

I know commonly people use dry-ice or LN2 to precool isopentane.But I wonder if -70C firdge could subsititute dry-ice for convenience?

 

BTW,how safe is isopentane? How will it explode?
