Description

Thermo Microm HM 450 Sliding Microtome

The Thermo Microm HM 450 sliding microtome is designed to section paraffin and frozen sections in biological, botanical, and materials science applications.

Thermo Microm HM 450 sliding microtome is equipped with automatic fine sectioning and trimming features with selectable specimen retraction. The integrated knife carrier glides along a maintenance-free precision cross-roller bearing system ensuring fast, comfortable, and non-tiring operation.

Stepping motor technology on the Thermo Microm HM 450 sliding microtome ensures precise and accurate knife-ward specimen advance. A trimming function allows for precision block trimming prior to the sectioning function. Automatic or manual sectioning can be selected.

The Thermo Microm HM 450 sliding microtome has a user-friendly control panel that allows for programming of settings and sectioning parameters. Time-saving memory function retains important sectioning information including section counter, step sum, remaining travel, and specimen position. This microtome provides specimen fine orientation on X/Y-axes.

Also featured on the Thermo Microm HM 450 sliding microtome is an integrated removable waste tray; knife holder with integrated, movable knife guard; retraction (may be turned off); motorized coarse feed with three different speed settings; and an ergonomic handle for moving knife carrier.
