Cryopreservation equipment

Years ago I saw an advertisment for a simple apparatus for slow-cooling
cells during cryopreservation. It was a plastic container that held the
vials surrounded by a chamber with a liquid -isopropanol, I think, to
modulate the cooling rate. I think that the whole container was placed
in the freezer to initiate cooling. 
We have been having trouble geting reproducable cooling rates and I
would like to try this system out but I have lost the advertisment.
Has anyone out there used this system or know who the manufacturer is?
