Colleagues

In regard to preservation of critical biological samples that need  
refrigeration at -70 C during a prolonged power outage, does anyone  
have experience in the use of liquid nitrogen as a back-up system,  
ie, I have read that some freezer units come with ports that one can  
hook the N2 to in such situations.
thanks -joe
