Freezing Microtome, LH 11.4
Freezing Microtome is designed to the full purpose of accurate and quick diagnosis in surgery and also for the inspection of quality of rubbes and others. It has a table clamping device. The specimen rises accurately and automatically by a handle. The CO2 freezing attachment is provided with a hard rubber non-conducting plate between the corrugated surface to which the object is frozen and the rest of the apparatus, which prevents the conduction of heat from the other parts of the apparatus to the specimen; thus saving time and CO2. In operating this freezing attachment the valve at the bottom should first be closed and valve at the cylinder slightly opened to admit the gas into the tube.
