Red Rain and washing plates
Thu Dec 19 16:00:51 EST 1996
I think it all depends on what the water is like where you work. My
daughter did a jr. high school sci project by analyzing various water
supplies around the Boston area and discovered that the tap water in
Cambridge, Massachusetts, had a pH of ca. 8.25! and the [F] was almost
off scale. An HPLC trace of the same sample looked like a profile of
the Rocky Mountains.
But still, we don't have to go to extremes in plate washing either. I
suppose our destiller does a good job. We've noticed green haze type
problems disappear when we replaced a slightly cracked cassette with a
new one and also, another time, when the service engineer realigned the
We don't need the paper towels either, just the "cling" wrap )at the
bottom) and avoiding excessive prerunning.
Ah! At last! Someone like me who doesn't go in for all this obsessive
cleaning business. I'm always reading posts to this group that say
like 'you must HCl wash your oplates every 2 days', 'alconox clean the
buffer tanks', never use this, always do that.......
I use any old alcohol thats going to wash my plates, I only ever rinse
the buffer tanks with normal tap water, I have cloudy 10x TBE and my
run perfectly, I get great reads, I get little or no gel haze. Does all
this acid cleaning just lead to more problems or am I just lucky? I
think its luck cos I havn't won the lottery yet :-(
