Complete Product Description

A unique sliding microtome with automatic fine/trim- feed system, specimen retraction during return travel. Maintenance-free precision cross roller bearings. For sectioning paraffin, frozen specimens and specialty applications in biological, botany, and materials science. Specimen sizes up to 80 x 60 mm can be accommodated. Performance, ergonomy and design of this sliding microtome with stepping motor far exceed today’s standards. The extraordinary smooth knife carrier movement guarantees fast, comfortable and non-tiring operation. Intelligent and modern electronic control systems coupled with high-precision mechanics result in optimal section quality and reproducibility of even difficult-to-cut embedded specimens.

The Sliding Microtome HM 440 E from MICROM International GmbH is a highly efficient instrument which can be used for paraffin, for very hard and large specimens for routine lab work, research and industry.

The maintenance-free cross roller bearings allow non-tiring work and a smooth sliding movement with optimal stability. The instrument is equipped with two integrated section waste trays, which are placed in front and behind the block. This way, section waste is directly collected. Moreover, the instrument can also be equipped with a small tray for liquid waste directly on the specimen clamps.

The HM 440 E will cut sections in a range from 1 to 100 microns. The specimen feed is carried out when the sledge is moved forwards. For the protection of knife and specimen, the instrument retracts the specimen at the end of the cut. If desired, the function can be turned off.

The motorized coarse feed system allows the continuous specimen up and downward travel with three different speed settings. This coarse feed system is controlled by a new multi-purpose button. This way, specimen and knife edge distance can be adjusted quickly.

A trimming function with defined steps from 10 to 500 microns permits the fine adjustment up to the first cuts and results in larger thicknesses when trimming.

The selected section thickness, trimming thickness, section counter, sum of section thicknesses and remaining travel to the upper end position are indicated on the display of the swivelling panel, which is placed on the left side of the microtome.

The knife carrier is designed so the knives can be easily clamped in place and adjusted and the coaxial specimen orientation allows orientation with one hand.
