Product Overview
The Roundfin RD-2265 is a high-performance cryostat designed for rapid intraoperative frozen section diagnosis in hospital pathology departments, research laboratories, and diagnostic centers. Featuring a dual-purpose knife holder compatible with both wide and narrow blades (0-15° adjustable angle), 6 semiconductor quick-freezing stations reaching -65°C to RT, with a minimum graduation value of 1°C, and a precision sectioning system delivering 0μm-999.9μm thickness in 0.1μm increments, the RD-2265 combines speed, accuracy, and advanced automation for demanding histopathology workflows.
The RD-2265 is equipped with one-key position memory, auto-alignment function, UVC ultraviolet sterilization, multi-user mode for personalized operator interfaces, programmable timing and sleep modes, and independent defrost for all cooling components (freezer, cooling stage, cooling knife, and cooling head). The double-layer heated glass sliding window with embedded heating coating ensures fog-free visibility. All functions are controlled via an intuitive touch screen interface. CE, ISO certified with 1 year and whole lifetime technical support.

Key Features
Microtome Knife Holder -- A dual-purpose holder for both wide and narrow blades, with blade lateral movement function. Adjustable angle from 0° to 15°, equipped with a retractable knife guard covering the entire blade edge and a glass anti-curling plate.
Timing Function -- Regular cooling, cooling stop, and sleep mode can all be set to start or stop at any time from Monday to Sunday.
Local Rapid Trimming Function -- Effectively improves work efficiency.
Position Memory Function -- The current chuck position can be saved by pressing a key and recalled directly next time.
Auto-Alignment Function -- When enabled, the tissue automatically moves to the blade edge, independent of tissue block thickness.
Real-Time Display of Sample Chuck Position -- With alarm at limit positions.
Real-Time Display of Waste Liquid Volume -- With prompt alarm when the set value is reached.
Switchable Modes -- Regular cooling, cooling stop, sleep mode, and low-temperature cooling mode.
Defrost Function -- Independent defrost for freezer, cooling stage, cooling knife, and cooling head. Both manual and timed defrost are available, with adjustable defrost duration.
Sterilization Function -- Equipped with a safe and effective low-voltage UVC ultraviolet lamp. Manual and timed sterilization are available, with adjustable duration.
Multi-User Mode -- Different users can log in to their own interface to access personalized functions and parameters.
Double-Layer Heated Glass Sliding Window -- The heating coating is between two layers of glass, maintaining heating performance even after long-term use and offering higher durability than single-layer glass.

FAQ
What section thickness range does the RD-2265 support?
Section thickness is adjustable from 0μm-999.9μm in 0.1μm increments. Trimming thickness operates in the same range and can be independently turned off. Tissue retraction is also adjustable from 0μm-999.9μm in 0.1μm increments to prevent section-to-blade contact.
How does the UVC sterilization function work?
The RD-2265 is equipped with a safe, low-voltage UVC ultraviolet lamp integrated into the cryostat chamber. Both manual activation and timed sterilization cycles are available, with adjustable duration. This helps maintain a hygienic working environment between procedures and is especially important for clinical pathology settings.
What is the multi-user mode?
Different operators can log in to their own personalized interface, each with customized functions, parameters, and preferences. This is particularly useful in shared hospital pathology labs where multiple pathologists or technicians use the same cryostat with different sectioning protocols and settings.
How long does it take to reach operating temperature?
The RD-2265 reaches operating temperature from standby in approximately 15min. The quick-freeze stage achieves -65°C to RT, with a minimum graduation value of 1°C with 6 semiconductor refrigeration stations. The programmable timing function allows you to schedule automatic cool-down and startup according to your lab's working hours.
