Hi All - Didn't want to bury this question in a RCM thread .....
But, finally splashed out on a RCM and need some distilled water (I have found IPA/ilfotol suppliers). I assume 99.9% purified is needed or better.
I've found a number of suppliers and they use different processes; the level of purification is either described, or not or is vague; costs obviously differ as does postage with some being free (nice !).
Question is: what spec do you use and where do you get yours from in the UK ?
thanks in advance
