KD-2950 Low-Temperature Cryostat Microtome
Product Introduction
The KD-2950 Low-Temperature Cryostat Microtome is a refrigerated microtome designed for preparing frozen tissue sections in histology, pathology, medical research, and biological laboratories. It combines rapid cooling, adjustable specimen retraction, convenient trimming and sectioning controls, UV disinfection, and an intelligent operating interface to provide stable and efficient frozen-section preparation.
The KD-2950 provides a freezing chamber temperature range of -10°C to -30°C. The freezing stage can reach -45°C, and below -55°C when the additional semiconductor cooling function is activated. The freezing stage can reach -30°C within approximately 60 minutes, helping laboratories quickly achieve the required sectioning temperature.

Performance Features
• Specimen Retraction Function: Adjustable specimen retraction helps prevent the sample from being scratched during return movement and improves section integrity.
• Quick Trimming Function: A dedicated quick-trimming button allows operators to conveniently switch between trimming and sectioning modes during operation.
• Section Counter: Displays the total number of sections and cumulative section thickness for convenient process monitoring.
• Rapid Cooling: The freezing stage can reach -30°C within approximately 60 minutes after startup.
• UV Disinfection: Uses ultraviolet disinfection with a standard 35-minute disinfection cycle.
• Switchable Semiconductor Cooling: The semiconductor cooling function can be switched on or off according to application requirements.
• Flexible Defrosting: Provides both timed automatic defrosting and manual defrosting modes.
• External Refrigeration Unit: The refrigeration unit is located outside the freezing chamber, reducing the effects of thermal expansion and contraction and minimizing maintenance requirements.
• Intelligent User Interface: An intelligent operating interface simplifies instrument operation and reduces the learning curve.
• Keyboard Lock Function: Prevents accidental or incorrect operation during sectioning.

Working Principle
The KD-2950 uses a refrigeration system to maintain the specimen and freezing chamber at low temperatures, allowing biological tissue samples to be sufficiently frozen for sectioning. After the specimen reaches the appropriate temperature, the microtome mechanism drives the specimen through controlled vertical movement while the blade performs precise cutting.
The specimen retraction function automatically retracts the specimen by a preset distance during the return stroke, reducing contact between the specimen and blade and helping protect the frozen tissue section. The adjustable semiconductor cooling system can further reduce the freezing stage temperature for samples requiring lower sectioning temperatures.
