title: Modification of the Reichert FC-2 cryoattachment to improve ultrathin sectioning reproducibility.
abstract: Modifications of the Reichert FC-2 cryomicrotome attachment which facilitate sectioning of frozen material are described. Most valuable was the construction of a specimen holder chuck made of brass and connected to the specimen arm with a glass rod. Other changes include improved shielding from heat influx, a constant nitrogen pressure cooling system and a stable cryochamber mount. These modifications considerably improve reproducibility.
