Some deparment stores sell it for ironing, tho most off that stuff is just deminiralised (bit less clean then distilled)Clown said:Where can I get distilled water from? I think that's what you call it... the water that conducts electricity less well than other water does.
I need to get some on the way home.
Cheers.

and you are right i think, deminiralised is used to cool nuclear reactors and is verry corrosivexane said:I thought it was called deionized ?
Scouse said:Deionised/Distilled. They changed the name a few years back from distilled to deionised....same shit.

I didnt realise McDonalds gave their employees net access! :kissit:Quick question, while I'm at work.
tbh purity is measured by how much "other stuff" is in the "pure" stuff you want. Ie H2O in this case.granny said:Not 100% right. Purity of water is measured in electrical resistance (once you get to a certain level of purity - before that you can just use parts per million of dissolved solids) - the higher the resistance the purer the water since there's less ions present to carry a charge.
Simple distilled water done "at home" as it were will possibly hit 1-5 megaohms (can't do the symbol dammit, it's a capital M and a capital omega), laboratory grade distilled & double-deionised water will get up to 10+ megaohms but stick a reverse osmosis system on that and a polisher cartridge and you'll get 18 megaohm water which is clean enough for most laboratory applications. For molecular biology people often UV treat that too and pass it through a 22 micron filter to ensure it's RNAse and DNAse free and sterile but tbh at 18 megaohms that's a bit belt-&-braces.
God that was possibly the geekiest thing I've ever posted here

Add a non-ionic substrate, and you still have "impure" water.....
I needed a quickish reply because I'm getting ready to buy something... I wonder whatClown said:(19:03:26) (_Clown_) if i buy an oem sata hard drive, and a brand new mobo, do you think i would have to buy that cable to connect it to the mobo?
The usual contaminants of water after an electrolysis purification are non-ionic. Simply because the only molecules this treatment will remove have to be electrically charged (ie ions). Filtration will only get rid of much larger...items in your water.granny said:Yes... but the usual contaminants of water after the usual purification processes used in laboratories don't include non-ionics, they're relatively easy to remove. It's the small ions that are a bitch to get out. Also resistivity of your water is easy to measure in real-time so you get an indication on an ickle readout on your reverse-osmosis system of how well it's working and if it's time to change the cartridges yet
