Subject: Liquid CO2 Quick Freezing Device?


Fellow Histonetters,

Does anyone know whether there is a current quick-freezer that's based on
liquid carbon dioxide?  These were popular several years (eons?) ago.  They
had a freezing stage connected to the valve from a siphon tube on a CO2
tank.
 They were quite simple, with no bells or whistles.  Just a valve you opened
to pass liquid CO2 through the stage.

If anyone has details on such a device, please contact me on- or off-list.

Thanks!
