Ricky Critcher asks about the Ultra Long Life Kr/Ar laser mentioned in
     our recent advertisements.  This laser has been developed as a part of
     Bio-Rad's continuing commitment to improved performance and
     reliability.  This water cooled 60 mW laser has warranted lifetime of
     4,500 hours and features self aligning mirrors.  Please contact your
     local Bio-Rad sales representative for further information.
 
     We apologise for the interruptions to Dr Critcher's research due to
     the sub-standard performance of the lasers on his system and assure
     all of our users that we are committed to prompt and efficient
     service.

Hi all.
 
In May I posted some concerns about the lifetime of the Kr\Ar laser on
our Bio-Rad MRC 600, and I thought you may be intersested in a follow up.
 
After purchasing another extended guarantee to cover lasers, the old one
was replaced with a refurbished laser. We have consequently gone through
3 of these,the last 2 lasers lasting 150 and twenty hours respectivly.
 
We have just had a new laser installed. It has been suggested I run a
sweep to see how long this lasts.
 
ps Did anyone see the ad. in last weeks Nature describing the 1024 with
an 'ultra long life Kr\Ar laser'? I have yet to find anyone from Bio-Rad
who can tell me anything about it!
