Abstract
Abstract A small container contains a frozen liquid or other coolant and is magnetically adhered to a metal microtome blade either by means of a permanent magnet disposed within the container or a magnetized metal wall portion on the container, for cooling the blade. The container may be sealed or refillable. There is also disclosed a container having inlet and outlet openings for permitting a continuous flow therethrough of coolant such as carbon dioxide from a dry ice source.
