Easy to get at most local pharmacy chains. Or you can get pure stuff speced for transformers at the link someone provided. (depending on how much you need) Works great. Note you DO NOT want any "real" transformer oil. It's mostly banned except in totally sealed devices and creates big disposal problems. And if it leaks can cause skin problems. And only works a tiny bit better than cheap old mineral oil anyway. And you don't want any of the cooking oils like peanut, sunflower etc. because they tend to turn rancid when oxidized. (peanut oil will smell great when hot, however :-)

Find an oil distributor that sells to industry. -- Lead free solder is Belgium's version of 'Hold my beer and watch this!'

The next step up is http://en.wikipedia.org/wiki/Fluorinert I've seen flourinert used in temperature testing components, though I'd have to rack my brain as to why they used it over a conventional oven. I think one of the Cray's was cooled with flourinert. |
