Key Features
- High-precision motor: Advanced stepper motor supports smooth, quiet and repeatable sectioning.
- Touchscreen interface: Displays section and trimming thickness, section count and specimen travel, with direct parameter adjustment.
- Rocking mode: Short forward-and-back handwheel movement enables controlled trimming without a complete rotation and retains the retraction function.
- Retraction and memory positioning: Adjustable specimen retraction helps avoid reverse blade contact, while one-touch memory return simplifies repeated trimming.
- Flexible specimen and blade handling: Quick-release specimen clamp system includes standard and universal cassette clamps. The holder accepts high- and low-profile blades, with an optional carrier for traditional steel knives.
- Adjustable blade holder: 0-15° cutting-angle adjustment, blade guard, blade remover and three lateral positions help use the complete blade edge.
- Safety and maintenance: Handwheel locking, alarms, overload protection, sleep mode, anti-static waste tray and long-term-lubricated rails support daily laboratory operation.
Applications
The RD-355AT ( New ) is intended for paraffin tissue sectioning in hospital pathology departments, independent diagnostic laboratories, research institutes, pharmaceutical and biotechnology laboratories, and medical teaching facilities. Rocking mode is useful for rapid controlled trimming, while continuous automatic cutting supports repetitive, higher-throughput workflows.
Optional Configurations
An external manual control panel or foot switch can provide remote adjustment of section or trimming thickness, specimen travel and cutting speed, plus cutting start and stop control. Horizontal and vertical travel, feed speed, maximum cutting speed, steel-knife carrier and emergency-stop configuration can be tailored to project requirements.
FAQ
What section and trimming thickness ranges does the RD-355AT ( New ) support?
The section range is 0.25-999 μm with a minimum 0.25 μm increment. The trimming range is 0.5-1000 μm with a minimum 0.5 μm increment.
What does dual-control mean on the RD-355AT ( New )?
The microtome can be operated through its integrated touchscreen and physical handwheel. An optional external control panel or foot switch adds remote parameter and cutting control.
How does rocking mode work?
Rocking mode allows short forward-and-back handwheel movement without a full rotation. It supports fast, controlled trimming while keeping specimen retraction active.
Which blades and specimen clamps are supported?
The standard configuration supports high- and low-profile disposable blades and includes standard and universal cassette clamps. A carrier for traditional steel knives is available as an option.
