Roundfin DualFit Microtome Blade Holder for Both High-profile and Low-profile Microtome Blade

Product Overview

The Roundfin DualFit Microtome Blade Holder is the world's first two-in-one solution that allows histology and pathology laboratories to use both high-profile and low-profile microtome blades in a single holder. Eliminating the need to purchase, store, and swap between separate holders for different blade types, the DualFit delivers convenience, cost savings, and workflow efficiency for laboratories that routinely use multiple blade profiles.

Precision-machined from high-grade stainless steel, the DualFit holder provides secure blade clamping with anti-vibration design that minimises chatter artifacts during sectioning. The quick-switch mechanism allows operators to change between high-profile and low-profile blade configurations without tools. Compatible with microtomes from Leica, Thermo Scientific (Microm), Sakura, and other major manufacturers, the DualFit is a universal upgrade for any histology laboratory.

Why the DualFit Blade Holder?

One Holder, Two Blade Profiles

Histology laboratories often need both high-profile blades (for dense or hard tissue specimens requiring a stiffer, thicker blade) and low-profile blades (for routine paraffin sectioning with standard tissue blocks). Traditionally, this meant purchasing two separate blade holders and swapping them on the microtome -- adding cost, bench space, and workflow interruption. The Roundfin DualFit eliminates this inefficiency by accommodating both profiles in a single holder with a quick-switch mechanism that requires no tools.

Anti-Vibration Precision Clamping

Chatter artifacts -- periodic thickness variations in tissue sections -- are one of the most common sectioning quality issues, often caused by blade vibration during cutting. The DualFit's precision-engineered clamping system securely grips the blade along its entire length, distributing clamping force evenly and minimising micro-vibrations that degrade section quality. The result is smoother, more consistent sections with fewer artifacts -- especially important for diagnostic pathology and quantitative histology applications.

Universal Microtome Compatibility

The DualFit is designed to fit Leica, Thermo Scientific, Microm, and Sakura microtomes -- covering the vast majority of rotary microtomes in clinical and research laboratories worldwide. The standardised mounting interface ensures secure attachment without adapters or modifications.

Factory-Direct Value

As a manufacturer, Roundfin supplies the DualFit blade holder directly to laboratories and distributors without intermediary markups. This factory-direct model delivers competitive pricing compared to OEM-branded holders while maintaining precision engineering and build quality. CE certified.
