Automated Rotary Microtome M-250
for paraffin-embedded tissue sectioning
The M-250 microtome from Myr uses state-of-the-art technology and embodies the company´s commitment to quality and excellence in the microtomy. It provides the operational convenience and the stability required for outstanding sectioning in routine, research and industry applications.
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.
All required parameters and functions are available on the main screen: section mode, speed, section and trimming thickness, section counter, section sum, remaining travel, retraction, coarse feed, memory function and cutting window.
|MEM key for higher productivity, to retrieve previous cuttings settings when working with uniform paraffin blocks. By simply pressing a key, the specimen moves into the stored MEM position.|
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
|Precise, motorized coarse feed in two modes, continuous and step. In continuous mode, speed is selectable between slow and fast to ensure a controlled specimen approach.|
Quick release specimen clamp
Cutting-edge design of the specimen clamp that prevents building up of dirt and facilitates operations with the microtome.
The retraction function selectable between 5 -250μ, which can turn off, prolongs the life of the blade. (Default value 40 μ)
Spacious waste tray
|Special antistatic coating prevents paraffin adhesion and minimizes the cleaning time. Ergonomic design with surface for arm rest. Wide area on the top of the microtome for the storage of tools.|
Knife carrier system
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.
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.
Embedded in the left side of the automatic microtome for speed/start-stop functions. It is possible to adjust the cutting speed while the motorized cut is running.
The entire touch screen functions are integrated into the external control panel for higher adaptability to technicians’ preferences. Optionally available.
Smooth and ergonomic handwheel
The handwheel is perfectly balanced thanks to an innovating counterweight system and can
