I am looking for a vendor that sells a quick-freeze chamber that connects
to a carbon dioxide cylinder.  This device is used to rapidly freeze tissue
for frozen sectioning.  American Optical used to sell such a device which
consisted of a plastic box with a hinged lid in which an object disc with a
specimen could be placed.  Using this, a fairly large block of tissue can
be frozen in seconds.  Does anyone know who supplies such a device?
