Ultra-low temp. freezer

[Hoyun_Lee at cancercare.on.ca]

     Hello! everyone,
     
     We are considering to purchase an "ultra-low freezer" to replace our 
     liquid N2-based cell-storage tank. The freezer, therefore, should be 
     able to go down to -150 degree C or lower. I would appreciate very 
     much if someone can advise me on this.
