Microm HM325 Rotary Microtome

The Microm HM325 rotary microtome provides extraordinarily high stability and precision as well as outstanding ergonomic characteristics. It is a highly efficient instrument which can be used for paraffin sectioning as well as for hard sectioning in any clinical, research, and industrial application.

The HM325 cuts sections in a range from 0.5um up to 60um. For the protection of knife and specimen, the instrument retracts the specimen at the end of the cut. The HM325 offers specimen retraction during return travel, quick trim feature at 10 and 30 microns and a section counter.

Forward and backward travel is carried out by the coarse feed wheel allowing quick adjustments of the specimen and knife edge distance. An additional trimming function offers two defined steps to permit fine adjustment up to the first cuts and results in larger section thicknesses when trimming.

The knife carriers of the Microm HM325 roatrory micrrotome are easy to use, can be moved sideways and are equipped with guards for user safety while adjusting the knife and specimens. A dovetail guide is screwed on the base plate. This guide is designed universally so that the different knife carriers can be clamped and moved to the front and the back.

A section counter with LC-display shows the number of sections made.

The Microm HM325 rotary microtome has an integrated, large section waste tray that is an exclusive design feature of Microm.
