<rant> Hm. Sometimes a simple power supply, instead of those high tech dingies (which claim that they do all the thinking for you) seems to do the trick. You simply adjust the voltage, set a maximum current and there you go. When the chamber wreaks havoc, you may turn the knobs and still get your results and don't loose your precious samples. -> Better check with those companies who provide power supplies for electronic labs, you'll get more value for your money. At least for people in Europe, this here is a good address: http://buerger-electronic.de/ (No affiliation, just a satisfied customer :) </rant> Wo _______________________________________________ Methods mailing list Methods@net.bio.net http://www.bio.net/biomail/listinfo/methods
