Hi all,
Over the last two days I checked every nook and cranny for my thermometer
standards, and thankfully just found them. With budgets tightening I had started
entertaining the idea of making my own replacements, and perhaps might have to
someday. I have some amateur glass blowing experience and am confident in avoiding
stressed-glass tube failures inside a magnet, also personal injury. My thought
was to use methanol and ethylene glycol 100%. But I'm not sure how strict they
ought be for solvent purity requirements. As in, a several year old 4L bottle is
fine, freshly distilled only, anhydrous analytical HPLC grade or bust...
Would anyone comment on how robust the temperature response curves for ppm
deltas actually are? Or if you've found flame sealing your own standards in
house worthwhile and not just a fool's errand?
Kind regards,
Luke
