Automated Rotary Microtome M-250

Features

• User friendly interface

Full color TFT 7” display with PCAD (projected capacitive) touchscreen. Size and tilt of the display allow an easy and effortless selection of the parameters and increase user safety.

• Memory function

• Specimen orienting head

Thanks to a blocking mechanism the easy to operate change system allows to work with different specimen clamps. Indication of 0-position in x and y direction by palpable “click” for the precise alignment of the specimen.

• Motorized specimen feed

• Quick release specimen clamp

The retraction function selectable between 5 -250μ, which can turn off, prolongs the life of the blade.  (Default value 40 μ)

• Spacious waste tray

• Knife carrier system

All blade holders are equipped with finger guard for safety reasons.

• Electronic brake

Once the automatic sectioning mode is paused, the electronic brake automatically activates, or alternatively, when sectioning manually, it can be activated by pressing the brake key on the touchscreen.

• Sectioning

The instrument is equipped with a simple and intuitive interface for quick learning. The high cutting quality helps to obtain precise sections while the smooth-working handwheel minimizes user fatigue, allowing you to improve your performance and have greater productivity.
