Frozen Slicer YD-1900, -55°C Specimen Holder (CAT#: STEM-AL-2438-ZJF)

The Frozen Slicer YD-1900 is a refrigerated sectioning instrument for preparing thin sections from frozen tissue. The cryochamber maintains a controlled low-temperature environment around the specimen and cutting assembly. Rapid-freezing positions support preparation of multiple specimen blocks before sectioning. The microtome advances the mounted specimen toward a blade while the handwheel or feed system controls cutting motion. Section and trimming settings are presented through the instrument control interface. Defrost, standby, and chamber-cleaning functions support routine maintenance of the cold workspace. Specimen orientation and anti-roll handling assist with producing flat sections for slide transfer. The instrument is intended for frozen-section pathology, histology, and research applications.
