title: An inexpensive replacement for dry ice in the laboratory.
abstract: A reusable inexpensive replacement for dry ice in laboratory use is presented. Commercially available small pellets of stone or metal can be stored in a -80 °C freezer and used for quickly freezing small samples with a freezing rate that is actually somewhat faster than with dry ice itself. Following use, the material is returned to the freezer to re-chill until the next usage.
