An ultramicrotome is a device which cuts specimens into very thin (30 to 50 nanometer) slices. The specimen is first embedded in a block of rigid material such as wax or epoxy. A glass or diamond knife is then used to cut the specimen. Typically the knife is mounted in a water trough which allows the sample to float in order to be collected for later microscopy.
