Product Description Ergonomic design Reproducibility of difficult-to-cut specimens Smooth sliding movement Maintenance-free cross roller bearings Automatic fine/trim-feed system Motorized coarse feed system The Microm HM 440 E Microtome is an ergonomically-designed sliding microtome that guarantees superior performance with its high functioning and advanced features. It employs state-of-the-art electronic control systems and high-precision mechanics to achieve optimal section quality and reproducibility of even the most difficult-to-cut specimens. It can accommodate specimen sizes up to 80 x 60 mm, and can cut sections ranging from 1 to 100 microns. Featuring extraordinarily smooth knife carrier movement, the HM 440 E Microtome offers fast, comfortable, and stress-free operation. Its maintenance-free cross roller bearings allow smooth sliding movement with optimal stability. The HM 440 also employs an automatic fine/trim-feed system to protect the knife and specimen by enabling specimen retraction during return travel. The HM 440 E Microtome also enables continuous upward and downward travel of the specimen through a motorized coarse feed system. This system employs three different speed settings and multi-purpose button control, allowing fast adjustment of specimen and knife edge distance.
