Documentation


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, 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.

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, that can be deactivated, helps extending the blade’s shelf life.


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

Blade holder slides sideways in both directions allowing the use of the entire cutting edge. It accepts low- and high-profile blades.

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

Smooth and ergonomic handwheel

The handwheel is perfectly balanced thanks to an innovating counterweight system and can be locked in any angular position. Cutting can be done by turning the handwheel clockwise or counterclockwise.

Smooth-working handwheel to minimize user fatigue.
