Key Features
- Dual operating modes: Switches between motor-assisted semi-automatic specimen feeding and trimming and manual handwheel trimming to suit different sectioning workflows.
- Dynamically balanced handwheel: The professionally balanced handwheel provides smooth, even resistance for comfortable operation during extended manual sectioning.
- Handwheel lock and automatic mode recognition: The feed handwheel locks at any 360° position, while the control logic recognizes partial-rotation trimming and full-rotation sectioning operation.
- Safety locking system: Handwheel and 360° position locks help prevent unintended movement during sectioning.
- Touchscreen and physical controls: A ≥5-inch full-color touchscreen and auxiliary physical keys support intuitive operation, including when wearing medical gloves.
- Specimen position memory: Stores specimen-feed coordinates and returns the specimen head to the saved position after changing paraffin blocks.
- Visual specimen orientation: Displays the specimen-clamp tilt angle in real time for controlled adjustment of the tissue cutting plane.
- Visible clamp zero reference: A clear zero-position scale helps operators quickly align the specimen origin.
- Real-time specimen travel display: The screen displays specimen-head travel and provides an audible warning at the forward and rear travel limits.
- Quick-release specimen clamps: Standard specimen and cassette clamps can be exchanged quickly. Optional configurations include a national-standard cassette clamp and forceps-style paraffin-block clamp.
- High-hardness universal blade holder: The high-hardness alloy holder supports precision sectioning of clinical soft tissue, bone tissue, polymer materials and plant samples.
- Anti-static non-stick blade-holder coating: A specialized anti-static, wax-resistant coating helps paraffin sections move smoothly and reduces sticking and wrinkling.
- Lateral blade-holder adjustment: The blade holder moves independently left and right without repositioning the blade, supporting stable fine adjustment of the cutting area.
- Adjustable blade holder with guard: The calibrated base supports a 0°-15° blade-angle adjustment. A full-coverage red blade guard with blade-ejection structure helps protect the operator from the cutting edge.
- Removable anti-static waste tray: The anti-static section-waste tray between the specimen clamp and blade holder can be removed for convenient cleaning.
- Optional dual-profile blade holder: An optional combined holder accepts both high-profile and low-profile disposable blades without replacing the complete holder assembly.
- Precision guide rails and machined components: Uses Japanese precision guide rails, core mechanical components processed on Japanese precision machine tools, and long-life lubrication for stable movement.
- Ergonomic molded housing: The integrated precision-molded enclosure provides a stable structure and an ergonomic layout for routine operation.
- Removable nano-silver antibacterial top panel: The corrosion-resistant nano-silver antibacterial metal top panel is removable for routine cleaning and maintenance.
- Automatic sleep mode: The instrument enters sleep mode after inactivity and wakes when a touchscreen control is pressed, reducing energy use and component wear.
Applications
The RD-Prime-SA660 is designed for routine paraffin-block trimming and sectioning in hospital pathology departments, independent histology laboratories, medical schools, pharmaceutical and biotechnology laboratories, and research facilities. Its 80 × 70 mm maximum section size also supports larger specimens when the selected clamp and blade holder are suitable.
Optional Configurations
Optional specimen-clamp choices include a national-standard cassette clamp and forceps-style paraffin-block clamp. An optional dual-profile blade holder accepts both high-profile and low-profile disposable blades without replacing the complete holder assembly.
FAQ
What sectioning and trimming ranges does the RD-Prime-SA660 support?
The section thickness range is 0-300 µm and the trimming thickness range is 0-1000 µm, with range-dependent increments listed in the technical specifications.
Which operations are motorized?
The instrument provides motor-assisted specimen feeding and trimming, with slow and fast feed speeds of 800 µm/s and 1800 µm/s. The handwheel provides manual sectioning and trimming control.
What specimen size can the microtome handle?
The specified maximum section size is 80 × 70 mm. Actual specimen compatibility also depends on the selected clamp, blade holder and preparation method.
Which blade and specimen-holder options are available?
The standard system supports quick-release specimen and cassette clamps. Optional configurations include a national-standard cassette clamp, forceps-style paraffin-block clamp and a dual-profile holder for high- and low-profile disposable blades.
