The Manual Microtome Series comprises three precision sectioning instruments designed for histological tissue preparation in research laboratories. Available in Standard (RF-RD-315), Professional (RF-RD-475), and Advanced (RF-RD-495) configurations, these microtomes provide section thickness control from 0.5–60 µm (RD-315) and 1–60 µm (RD-475, RD-495) with variable increment settings optimized for different thickness ranges. Each model incorporates specimen retraction capability, replaceable cassette holder systems, and imported cross-roller guide rails for consistent sectioning performance.
The series features adjustable knife and specimen angles with 360° rotation capability. Advanced positioning systems enable X and Y axis adjustment with ±1% precision, while the screw motion mechanism and handwheel provide controlled tissue advancement. Maximum specimen accommodation is 60 mm × 50 mm across all models, with vertical stroke of 52 mm (RD-315), 60 mm (RD-475), and 70 mm (RD-495) to support diverse tissue block sizes in histopathological workflows.

How It Works
Manual microtomes operate through controlled mechanical advancement of tissue blocks against a fixed cutting blade. The specimen holder advances the tissue block in precise increments determined by the thickness setting, while the operator applies consistent cutting motion across the blade edge. The screw motion mechanism converts rotational input from the handwheel into linear specimen advancement, with imported cross-roller guide rails ensuring smooth, vibration-free movement.
Section thickness is controlled through graduated increment settings that vary by thickness range: 0.5μm increments for 0-2μm sections, 1μm increments for 2-10μm sections, 2μm increments for 10-20μm sections, and 5μm increments for 20-60μm sections. The specimen retraction feature allows the tissue block to move away from the blade during return strokes, preventing compression artifacts and maintaining section integrity.
Specimen orientation adjustment enables optimal cutting angles for different tissue types, while the replaceable cassette holder system accommodates standard histological cassettes. The trimming function allows removal of excess tissue before sectioning, improving section quality and blade preservation.

Practical Tips
Verify thickness settings monthly using calibrated test blocks or micrometers to maintain sectioning accuracy.
Why: Mechanical wear can gradually affect thickness precision over time.
Clean and lubricate guide rails weekly using recommended lubricants to prevent binding and ensure smooth operation.
Why: Proper lubrication prevents premature wear and maintains sectioning consistency.
Allow paraffin blocks to equilibrate to room temperature before sectioning for optimal ribbon formation.
Why: Temperature affects paraffin hardness and cutting characteristics.
If sections compress or fold, check blade sharpness, cutting angle, and ensure specimen retraction is functioning properly.
Why: Multiple factors can contribute to sectioning artifacts requiring systematic evaluation.
Document sectioning parameters including thickness, specimen orientation, and environmental conditions for reproducible results.
Why: Consistent documentation enables protocol optimization and troubleshooting.
Always engage blade guards when not actively sectioning and use proper blade disposal procedures.
Why: Microtome blades are extremely sharp and pose significant injury risk if handled improperly.
Trim excess tissue using the trimming function before beginning serial sectioning to improve section quality.
Why: Removing excess material reduces blade wear and improves ribbon formation.
Store the microtome with specimen holder retracted and blade removed to prevent accidental contact and damage.
Why: Proper storage prevents component damage and extends instrument life.

The microtome maintains ±1% precision accuracy across the 0.5-60μm range, with graduated increment settings optimized for different thickness ranges to ensure consistent results.
How does the specimen retraction system prevent tissue artifacts?
The retraction mechanism moves the tissue block away from the blade during return strokes, eliminating compression forces that can distort tissue morphology and create sectioning artifacts.
What is the maximum tissue block size that can be accommodated?
The microtome accepts specimens up to 60mm × 50mm in cross-section with 52mm vertical stroke, covering most standard histological cassette sizes.
