Product Overview
The RD-MF55 microtome is widely used in hospitals, education, disease prevention and control, forensic laboratories, agriculture, veterinary medicine, scientific research institutions, and related laboratories.
The Roundfin RD-MF55 is an advanced tissue microtome featuring an integrated SDS Section Transfer and Flotation System that combines precision sectioning with automatic water-bath transfer for streamlined histology workflow. Equipped with a 5-inch color touchscreen, the RD-MF55 displays real-time sectioning parameters and provides intuitive control over all functions. Key capabilities include switchable dry/wet sectioning modes, an adjustable section thickness range of 0.25–1000 µm, a paraffin block/clamp cooling system (0°C–10°C) for prolonged block temperature stability, specimen retraction (0–1000 µm (adjustable)), and a precise motor-driven feed system that maintains constant sectioning speed for consistent results.
The integrated SDS Flotation Bath features temperature-controlled flowing water (20–60°C (adjustable) adjustable) with a 1.0 L capacity, gently transferring sections onto the water surface. Built-in illumination allows immediate section inspection and selection. The RD-MF55 supports both manual and automatic operation, rock mode for challenging specimens, and can be expanded with stereomicroscopes, rapid cooling devices, and other auxiliary equipment. Available in both wet-sectioning (640 × 490 × 340 mm mm) and dry-sectioning (550 × 490 × 340 mm mm) configurations.

FAQ
What section thickness range does the RD-MF55 support?
The RD-MF55 offers 0.25–1000 µm with adjustable increments (0.25/1/2/5/10/20/50/100um). Trimming range is the same. Accuracy is ±5%.
What is the SDS Section Transfer/Flotation System?
The SDS system uses temperature-controlled flowing water to gently transfer sections from the blade into the flotation bath. The bath heats from 20–60°C (adjustable) with 1.0 L capacity. Built-in illumination allows immediate section inspection.
Can the RD-MF55 be used without the SDS system?
Yes. The RD-MF55 supports switchable dry/wet sectioning modes. In dry mode, the microtome operates as a standalone unit (550 × 490 × 340 mm mm, Net 35 kg / Gross 42 kg). The SDS system can be added or removed as needed.
Does the RD-MF55 support frozen sectioning?
Yes. With an external cooling unit, the RD-MF55 can freeze specimens to -15°C. The block clamp cooling system (0°C–10°C) maintains low temperature for prolonged section quality.
What accessories are available?
The RD-MF55 is compatible with additional specimen clamps, knives, blade holders, stereo microscopes, rapid cooling devices, and auxiliary equipment. Contact our team for a complete configuration.
