	Thanks, Gary and others, for your comments!

	Hmmm.  O.K., I hadn't considered this.  I used the Perkin-Elmer
GeneAmp tubes that we use with our old TC-1 thermal cyclers (yes, we have
a few PCR machines in our lab -- two TC-1's and a 9600 -- we do a lot of 
sequencing).  The folks who own the Robocycler may have a stash of Strata-
gene plasticware somewhere.

	I did overlay my samples with mineral oil, but I did not add any min-
eral oil to the wells on block 1.  As the machine does not presently have any
oil in any of the blocks and the machine does not belong to our lab, I suspect
that this will not be a welcome suggestion... but I'll ask.

>Both of these suggestions are made in the Robocycler manual.

	Ah, yes!  The manual!  As I mentioned in the original post, my other-
wise helpful and generous colleagues have lost this important document.
