Reversal

Today I discovered that high-pressure carbon dioxide can blow a microthermocouple out of its capillary if the end of the capillary is not sealed. This possibility never occurred to me. I fact, I never realized that the pressure inside the tube where I want to measure the temperature would be pretty high.

While this is a disappointment, it also suggests a new way of getting the wires inside the capillary in the first place.
