[RASMB] Aluminum SV Cell Corrosion

[E. James Petersson]

Dear Colleagues,

Recently, I used aluminum centerpieces for the first time and found  
what appears to be corrosion on both the centerpiece as well as the  
cell housing.  The cell was allowed to sit for about 1 week after the  
run was complete before cleaning.  I did not notice substantial  
leaking (the sample and reference channels were not noticeably  
depleted), but clearly some leaking must have taken place.  My buffer  
is 10 mM phosphate, 200 mM NaCl, pH 7.2.
If anyone has any advice regarding 1) cleaning off the corrosion, 2)  
whether this cell is still usable, or 3) how to prevent this in the  
future, I would appreciate it.

Thank you,
James
