HELP! MY PRECIOUS MIRROR IS IN DANGER!


Recommended Posts

Price is £570 plus VAT. There is a misprint in rthe specification, the water quality should read 1 - 10 megohm per cm. These were as common  as anything when I was chemistrying.

We had something similar at Newcastle University in the Physics Department. I did not pay any attention at the time as we just used what we needed. At home ,I used deionised and distilled water but fed it though a series of filters I had bought for treating water for my Koi these were granulated carbon and heavy metal filters. They were expensive as well but not more than about £70 for the heavy metal filter (long time ago). Don't have the fish now so no filters. You can use Doulton Ultra carb filters. These can take out impurities and particles down to about 0.5 to 0.9 micron. Meant for normal water treatment but capable of removing heavy metals. They are supposed to be used in  pressurised systems, i.e. mains water, but will work OK if you use a good head of water, albeit very slowly. Cost about £22 each but the housing also costs to begin with:

I don't jest but if you want to 'polish' distilled or deionised water for cleaning an ordinary Brita-style activated carbon filter is probably just as good., just make sure you rinse through a few times to get rid of any loose carbon.
