Roundfin Dualfit Microtome Blade Holder

NHS histopathology departments, hospital pathology laboratories, and diagnostic services operating both Thermo Scientific and Leica microtomes represent the primary procurement context for the Roundfin Dualfit Microtome Blade Holder. The dual-platform compatibility — covering both Thermo Scientific and Leica instrument families — means that a department with a mixed microtome estate can standardise on a single blade holder model rather than procuring separate holders for each platform. The magnetic strip enables both low-profile and high-profile blades to be used in the same holder, further simplifying blade holder stock management. Medigear.uk supplies the Roundfin Dualfit Microtome Blade Holder and can provide NHS procurement documentation.

Surgical pathology departments, cancer diagnostic centres, and high-throughput histopathology services benefit from the three-section blade design, which ensures 100% utilisation of the cutting edge and maximises blade service life. In high-volume departments where blades are changed frequently, extending effective blade use per unit reduces consumable cost and reduces the frequency of sharps-risk blade change operations. The push-rod change mechanism supports safer blade changes in busy high-throughput sectioning environments. Medigear.uk can advise on the procurement of Dualfit for high-volume pathology settings.

Research histology laboratories, university histology departments, and translational pathology units that use both Thermo Scientific and Leica microtome platforms benefit from Dualfit's cross-platform compatibility, which avoids the need to hold separate blade-holder stocks for each instrument brand. The 0–12mm upper adjustment range accommodates different tissue block dimensions, and the three-section blade design supports consistent section quality across varied research tissue types. Medigear.uk can advise on Dualfit configuration for research and academic procurement.

If you run private pathology services or a commercial histopathology facility and need a versatile, low-maintenance blade holder for mixed Leica and Thermo Scientific microtomes, the Roundfin Dualfit is available through Medigear.uk.

Magnetic Strip for Dual Low-Profile and High-Profile Blade Security

The magnetic strip is the defining feature of the Dualfit — it holds both low-profile and high-profile blades securely in the same holder body without a profile-specific mechanical selector or holder swap. For laboratories using both blade profiles, this eliminates the need to maintain two separate blade holder stocks and removes the holder-change step when switching between profile types.

Compatible with Thermo Scientific and Leica Microtomes

The Dualfit covers the two most widely deployed microtome platforms in NHS histopathology — Thermo Scientific and Leica. Departments with a mixed microtome estate can standardise on a single blade holder model, simplifying procurement and reducing the number of accessory SKUs that need to be stocked and managed.

Three-Section Blade Design — 100% Cutting Edge Utilisation

The three-section blade design allows the full width of the cutting edge to be used, rather than only the central portion. The brochure confirms this ensures 100% cutting-edge utilisation, maximising blade service life and cutting efficiency—a meaningful cost and safety benefit in high-volume sectioning environments where blade change frequency, and sharps waste are important operational metrics.

Push-Rod Blade Change — Reduced Sharps Contact

The push-rod mechanism ejects and seats blades without direct handling of the blade edge, reducing the risk of sharp injury during blade changes. In high-throughput histopathology departments where blades are changed multiple times per session, this design-level sharps risk reduction is a consistent operational advantage.

Red Safety Guard for Operator Protection

The red safety cover prevents blade contact during blade change and during normal sectioning operation. It is a fixed design element that protects the operator without requiring additional PPE beyond standard sharps safety protocol.

0–12mm Upper Adjustment for Tissue Block Fitting

The upper part is adjustable over 0–12mm to set the holder height for the tissue block in use. This improves blade-to-block contact consistency and supports accurate section thickness across different block dimensions.

Anti-Stick Upgrade Technology

Engineering upgrades address blade sticking during sectioning — a common cause of section quality failure. The Dualfit incorporates this improvement at the design level, contributing to consistent section quality during routine and research microtomy.

Compact 2.4kg Design with Customisation Available

Net weight 2.4kg in the standard L13.9cm×W7.9cm×H10cm body. We offer low- and high-profile blade holder customisation for OEM and institutional buyers. Contact Medigear.uk for customisation options.
