The Manual Rotary Microtome For Outstanding Durability, Precision and Comfort

As Durable as Ever, Enhanced Precision and Comfort Like Never Before: The New Leica RM2235

Durability is essential in a manual microtome and the Leica RM2235 can stand up to the workload requirements of even the busiest laboratories. The enhanced precision of the new accessories will add convenience to block to knife approach as well as specimen orientation.

The new Leica RM2235 manual microtome provides unique user-friendliness, achieved through numerous new features, most of them patented, which have never before been offered in this class of microtome. The Leica RM2235 combines proven technology with well thought-out ergonomic details and the highest safety standards.

Working in comfort is not a luxury but a necessity. A relaxed, ergonomic working posture is a basic prerequisite for the high levels of speed, precision, and efficiency required in modern laboratories. Day after day, the new Leica RM2235 provides comfortable functionality without compromise. The RM2235 is the instrument of choice for all clinical histology and histopathology institutions where manual microtomes are preferred over motorized units.

Safety during sectioning

Safety is ensured by the integrated, red finger protection guard of the knife holder E that uniquely shields the blade edge. When used correctly the integrated finger protection guard rules out potential injuries because it can even remain on the blade edge during sectioning

Convenient storage area

An integrated storage tray* ensures that ancillary tools are on hand at all times. Alternatively a cooling plate with thermo element can be used for cold storage of specimen blocks either on top or on either side of the microtome.

Fatigue-free operation

Ergonomics and user comfort were prime considerations for the location of the coarse feed wheel, which is positioned close to the operator. The direction of the handwheel rotation to best suit your sectioning style can be specified at the time an order is placed. The mechanical trimming function, conveniently placed next to the coarse feed wheel, eliminates the need to turn the coarse feed wheel during trimming.

Spacious, magnetized section waste tray

The spacious section waste tray reliably collects sectioning debris. It is safely held in position by magnets, yet is easily removable for emptying and cleaning.

Ergonomics and user safety

The smooth-running safety handwheel has an ergonomically shaped handle. A handwheel locking device for one-thumb operation locks the specimen head in the uppermost position, which is ideal for changing the specimen and/or blade. A second locking mechanism on the microtome base allows the object head to be locked in any position.

The patented force balancing system

The RM2235 handwheel runs exceptionally smoothly because it has no balancing weight. Instead, the patented force balancing system uses a spring to compensate the forces generated during sectioning. The result: effortless operation and uniform handwheel rotation – producing much better sectioning results.

Fast sectioning without specimen orientation

For applications where specimen orientation is not needed, a non-orienting fixture for specimen clamps is available as an optional accessory. The Super Mega cassette can clamp specimens up to a size of 46 x 66 x 10 mm (W x H x D).

Precision specimen orientation with clear zero reference point

This novel orientation mechanism sets new standards of precision and is very easy to operate. Calibrated controls make it easy to adjust a specimen to an exact zero position indicated by red pins or a measurable variable on the x/y axis for re-cuts.

Lateral knife holder adjustment

The entire width of the microtome blade can be used without having to release the blade clamping mechanism. Using the entire knife edge is cost effective, especially in laboratories with high specimen throughput. Three predefined stop positions (left, center, right) correspond to the width of a standard histology cassette.

A special accessory: Chilled universal cassette clamp (UCC)

The UCC is kept cold by placing ice cubes or dry ice in a special compartment, which ensures that specimen blocks remain at cold temperatures throughout the entire sectioning process.

Well thought-out and proven:

Knife holder Base

universal knife holder base fits virtually all Leica knife holder systems.

Universal cassette clamp for single-hand operation

definitely THE easiest way to clamp/remove specimens.

Optimized microtome Base plate

provides maximum rigidity – thanks to the latest technology and new lightweight materials.

One-piece housing

made from specially resistant plastic, without any edges where debris could accumulate, which reduces cleaning to a minimum.

Fewer clamping levers

makes the Leica RM2235 easier to use by providing improved access to the cutting area.
