Leica RM2235: Robust and Ergonomic Manual Microtome for Clinical Histology
The Leica RM2235 is a manual rotary microtome designed for laboratories seeking a reliable, precise, and user-friendly instrument for daily use. Built to withstand high workloads, it is well-suited for hospital environments, research laboratories, and histotechnology training schools. It stands out for its mechanical robustness, sectioning quality, and user-centered ergonomics.
Unlike motorized microtomes, the Leica RM2235 relies on manual operation without compromising the smoothness of movement. Its handwheel, extremely easy to handle, operates with a patented spring-based force compensation system, ensuring smooth and effortless rotation. This technology enhances section quality while reducing user fatigue, even after extended periods of use.
Ergonomics were central to the design of this instrument. The coarse feed handwheel is located close to the operator, allowing for a natural and strain-free motion. The direction of the handwheel rotation can be specified at the time of order to suit each user’s sectioning habits. The handwheel lock, operable with a single thumb, secures the cutting head in the upper position for safe blade or specimen changes.
The microtome features an integrated tray for tool storage, as well as a wide, easy-to-clean magnetic waste tray. This tray remains securely in place during use thanks to a reliable magnetic system. An optional version with a cooling plate is available, ideal for keeping blocks at low temperatures during sectioning.
For cases requiring specimen orientation, the Leica RM2235 offers an orientation system with a visible zero point, enabling precise re-trimming. For non-orientation applications, a fixed specimen holder is also available. The device can accommodate large-format cassettes up to 50 x 66 x 30 mm, with specific versions available for Super Mega cassettes (46 x 66 x 10 mm).
User safety is ensured through multiple integrated features. The universal blade holder base is compatible with most Leica blade systems. The disposable blade holder includes a red finger guard, which can remain in place during sectioning if needed, reducing the risk of injury. The specimen clamp lever is designed for one-handed operation, simplifying handling procedures.
The microtome base is optimized for excellent stability, with a one-piece structure made from durable material and no sharp edges where paraffin could accumulate. The entire unit is easy to clean, helping maintain strict hygiene within the lab. The lateral adjustment system of the blade holder allows the full width of the blade to be used without loosening it, extending blade life.
Designed to combine performance, safety, and ease of use, the Leica RM2235 remains a benchmark instrument for all histology professionals seeking a reliable and long-lasting tool.
