Semi Automated Rotary Microtome

The M-240 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.

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, section and trimming thickness, section counter, section sum, remaining travel, retraction and coarse feed, memory function.


Memory function

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.
