ThermcoPoly1 going gold

I am receiving your emails and I hear your concerns.  I know 
transitions like this are difficult and how impossible it is to find 
the perfect time.  We are not out to jeopardize your work, but we are 
trying to support the lab members who for years have been asking for 
more capability in processing substrates in the gold contaminated category.

The intention of the earlier email was to remind everyone one the 
change is coming.  Maurice has been working on gathering data on 
Thermcopoly2.  We must get a complete set of data, have it published 
and have it reviewed by the lab member community before the 
change.  I will be gathering the data out of Thermcopoly2 and will 
monitor the progress in Maurice's absence.  But be clear, the 
objective is to provide poly processing support for non-clean or gold 
contaminated substrates.  This means one of the poly tubes has to 
change.  From the emails, it seems like the end of March should be 
the target for the conversion if we meet the criteria mentioned 
above.  Out of fairness to the projects which are waiting for the 
conversion, we do need to set a target date.  The number of current 
Thermcopoly1 users who are impacted by this change is similar to the 
number of lab members who are waiting.
