Hi Jennifer!

We used an FTS Systems FC100 Flexi-Cool immersion 
cooler with our dual-inlet Optima mass spec with 
very few problems for 16 years before the mass 
spec was moved to another institution.  We had it 
serviced once during that time when a small 
amount of debris partially clogged its cooling 
lines.  Other than that one time, we never had an 
issue with it reaching a temperature below -95°C.

FTS Systems products seem to be handled by SP Scientific now.  See the link
