Microtome Specimen Clamp | Roundfin
1. High-quality aluminum alloy construction — lightweight yet rigid clamp body with anodized finish for corrosion resistance and long-term durability
2. Universal microtome compatibility — fits all Roundfin rotary microtomes and major brands (Leica, Thermo, Sakura) via standard dovetail or quick-release mount
3. Dual application design — accommodates both paraffin block clamps for embedded tissue blocks and cassette clamps for rapid cassette-based sectioning
4. Quick-release lever mechanism enables rapid specimen exchange between blocks without tools, minimizing microtome downtime in high-throughput labs
5. Precision-machined clamping surfaces ensure parallel block alignment for consistent ribbon formation and uniform section thickness
6. CE marked and manufactured under ISO 13485 quality standards for clinical histopathology laboratory use
Product Overview
The Roundfin Microtome Specimen Clamp is a precision-machined aluminum alloy clamping system that securely holds paraffin-embedded tissue blocks and processing cassettes during microtome sectioning. The dual-application design accommodates both standard paraffin block chucks and rapid cassette-based sectioning workflows. A quick-release lever mechanism enables tool-free specimen exchange in seconds, minimizing downtime between blocks in high-throughput histology laboratories.

Key Features
- Dual Application Design — Accommodates both standard paraffin block chucks for embedded tissue blocks and cassette clamps for rapid cassette-based sectioning without changing the clamp assembly.
- Quick-Release Lever Mechanism — Tool-free specimen exchange in under 5 seconds; simply flip the lever to release the current block, insert the next, and flip back to lock — maximizing sectioning throughput.
- Lightweight Aluminum Alloy — High-strength aluminum construction with anodized finish provides corrosion resistance, easy paraffin cleaning, and reduced microtome arm wear compared to heavier steel clamps.
- Precision Parallel Alignment — CNC-machined clamping surfaces ensure the block face is perfectly parallel to the blade edge, eliminating wedge-shaped sections and ensuring uniform ribbon thickness across the entire block surface.
- Universal Microtome Compatibility — Standard dovetail mount fits all major rotary microtomes; quick-release adapter plates available for non-standard mounts including older manual microtome models.
- 360° Rotation with Z-Adjustment — Full block rotation for optimal tissue orientation relative to the blade, plus Z-axis height adjustment for precise block-to-blade approach without adjusting the microtome stage.
Applications
- Routine histology and pathology sample-preparation workflows
- Clinical laboratories processing compatible specimens, blocks or slides
- Research and teaching facilities using microscopy and tissue-processing supplies
- Laboratories confirming size, material and equipment compatibility before ordering
Frequently Asked Questions
Does this clamp work with my microtome model?
The Roundfin specimen clamp uses a standard dovetail mount compatible with Roundfin RD-315/335/355AT, Leica RM series, Thermo Scientific HM series, and Sakura Accu-Cut microtomes. For older manual microtomes or non-standard mounts, contact Roundfin for an adapter plate — we can engineer a custom adapter for virtually any rotary microtome configuration.
How do I switch between paraffin block and cassette clamping modes?
The dual-application design allows switching by adjusting the clamping jaw width and inserting the appropriate adapter insert (included). For paraffin blocks, use the wider jaw setting with the block chuck adapter. For cassettes, use the narrower jaw setting with the cassette adapter. Both adapters are included with the clamp. Switching takes approximately 30 seconds.
How should I clean the specimen clamp?
After use, remove paraffin residue with xylene or a suitable solvent applied to a lint-free wipe. Avoid abrasive scrubbers that could scratch the anodized surface. The quick-release mechanism should be periodically inspected for paraffin buildup that could impede smooth operation. Do not autoclave the aluminum alloy clamp — use chemical disinfection with 70% ethanol or isopropanol for decontamination between users.
What is the warranty period?
The Roundfin Microtome Specimen Clamp is covered by a 12-month warranty against manufacturing defects. The anodized aluminum construction is designed for 5+ years of daily use in standard histology laboratory conditions. Roundfin provides replacement quick-release lever assemblies and adapter inserts as spare parts. Contact Roundfin for warranty service or spare part ordering.
