FAQ
What is the section thickness range?
The RD-475 offers 0-60μm with three precision intervals: 0-10 μm (0.5 μm steps), 10-20 μm (2 μm steps), and 20-60 μm (5 μm steps).
How does manual differ from semi-auto models?
The RD-475 is fully manual — section thickness is set mechanically and the handwheel is hand-operated. No touch screen or motorized feed. This means lower cost, zero electronics maintenance, and no power requirement.
What safety features are included?
The handwheel has a top lock and 360° position lock. The blade holder includes a safety guard and easy-disassembly function to prevent operator injuries.
Is the RD-475 suitable for teaching?
Yes. The simple manual design and dual-locking handwheel make it ideal for teaching environments. No complicated electronics to manage, and students learn core microtome operation principles.
