Product Overview
The Roundfin RD-2260 is a high-performance pathology cryostat microtome designed for frozen section preparation in hospital pathology departments, research laboratories, and diagnostic centers. Powered by two original German Danfoss brand compressors with dedicated independent cooling for the freezing chamber, freezing shelf, knife blade, and specimen clamp, the RD-2260 delivers reliable, uniform low-temperature performance for consistent frozen section quality.
Featuring an LED touch screen displaying the total number of sections, total trimming thickness, section thickness, specimen retraction value, temperature control, date, time, temperature adjustment, and switch status with Chinese/English interface switching, the RD-2260 combines precision engineering with intuitive operation. The chamber temperature is adjustable from -10°C to -40°C, adjustable with a standby mode that maintains -1 to -9°C and restores working temperature within 15 minutes. The freezing shelf reaches -45°C and accommodates 26 specimens simultaneously. Two dedicated Peltier stations achieve -65°C in just 15min for rapid intraoperative frozen sections. CE certified.

Key Features
LED Touch Screen -- Displays the total number of sections, total trimming thickness, section thickness, specimen retraction value, temperature control, date, time, temperature adjustment, and switch status. It also supports switching between Chinese and English operation interfaces.
Standby Mode -- In standby mode, the cryostat chamber temperature is automatically controlled between -1°C and -9°C. After standby mode is stopped, the system restores the working temperature within 15 minutes.
Dual Compressor Refrigeration -- Uses two original German Danfoss brand compressors, with dedicated cooling for the chamber, freezing shelf, knife blade, and specimen. The blade holder also includes a protection bar for operator safety.
UV Sterilization -- Supports UV sterilization.
Chamber Storage -- Includes a waste tray and storage rack inside the chamber.
Fully Enclosed Chamber Interior -- Freezing chamber interior parts use a fully enclosed design for improved temperature uniformity and easier cleaning. Includes a waste tray and storage rack inside the chamber.
Large Quick-Freeze Shelf -- Accommodates up to 26 specimens simultaneously at -45°C, significantly improving workflow efficiency for high-volume frozen section preparation.
Low-Noise Operation -- Operating noise is less than 50dB(A), creating a quiet and comfortable workspace suitable for extended laboratory sessions.

FAQ
What compressor system does the RD-2260 use?
The RD-2260 is equipped with two original German Danfoss brand compressors providing dedicated independent cooling for the freezing chamber, freezing shelf, knife blade, and specimen clamp. This dual-compressor design ensures consistent, reliable low-temperature performance.
How does the standby mode work?
In standby mode, the cryostat chamber temperature is automatically controlled between -1 and -9 °C. When standby is deactivated, the system restores the working temperature within 15 minutes. This energy-saving feature allows the instrument to remain in a ready state between cases without consuming full power.
How many specimens can be frozen simultaneously?
The large quick-freeze shelf accommodates up to 26 specimens at -45°C for routine batch processing. Additionally, 2 dedicated Peltier stations provide rapid freezing to -65°C in approximately 15min for urgent intraoperative frozen sections.
What safety features does the RD-2260 include?
The RD-2260 includes a blade holder with protection bar for operator safety, a 16-position handwheel locking mechanism, UV sterilization for chamber disinfection, and a fully enclosed chamber interior design that improves temperature uniformity while preventing frost accumulation on mechanical components.
