The sliding microtome HM 450 from Thermo Scientific is a highly efficient instrument with specimen retraction during return travel. It is equipped with automatic fine sectioning and trimming features with selectable specimen retraction.

The unit is designed to section paraffin and frozen sections in biological, botanical, and materials science applications. The integrated knife carrier glides along a maintenance-free precision cross-roller bearing system ensuring fast, comfortable, and non-tiring operation. Stepping motor technology 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 user-friendly control panel 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. Unit provides specimen fine orientation on X/Y-axes. The HM 450 also features 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.

All of our equipment is used and reconditioned. Our technicians test all equipment to confirm that it operates properly and to the manufacturer’s specifications. While we can’t test for a specific analytical application, we will do our best to simulate the conditions under which the equipment will be run. If you have particular testing requirements or requests please let us know and we’ll work with you to make sure these requirements are addressed during testing.

The photos above are representative. Please bear in mind that the equipment shown is currently in storage in our warehouse and that in addition to testing each machine we will clean all the equipment thoroughly prior to shipment. We often have multiple units of each model in stock and sometimes we're unable to feature photos of every single unit. At your request, we can provide photos of the equipment in your order after it has been tested and cleaned.
