Hi Everybody,
   I found the holder today covered (like over 4") with little black
specks. They came off in IPA, so i presume they were the sticky dots.
Please clean the holder if what you put in leaves something behind! I am
also concerned about this stuff migrating to the column, where recently we
had major contamination problems,
 Thanks,
Dan
