[Re: Phase II] But about BCAL BC-600 <<< For George

["Dr. Paul Eugenio" <eugenio@fsu.edu>]

Hi,

Eljen Technology make an equivalent of BC-600 called EJ-500.  I have
purchased many Bicron equivalents from Eljen with substantial savings.
This could turn into large cost saving especially, if I recall
correctly, that the total projected BC-600 cost was ~200 k$.  

I am almost positive that EJ-500 is exactly BC-600.   I can contact 
Chuck Hurlbut from Eljen and confirm this.  Chuck, some may recall, was
the head chemical engineer for Bicron who started his own company named
after his daughters Ellen and Jenny.
