Rotary microtome

Leica RM2125 RTS

The rotary microtome allows cutting sections with adjustable thickness from 0.5 to 500 micrometers from solid specimens and specimens embedded in a paraffin block.

Microtome with vibrating blade

Microm HM 650 V (Thermo Scientific)

The Microm HM 650 V microtome is a highly efficient microtome with a horizontally oscillating blade for semi manual as well as fully automated sectioning of mainly neuronal tissue.

Features: Precise vibrating system produces minimal deflection, ensuring optimal specimen integrity Plug and play system does not require time-consuming deflection adjustments for each different sample type Sectioning and operational parameters can be stored and recalled Micrometer and vibration systems enclosed in an ergonomically designed housing Three modes of operation: semi-manual, single and continuous Specimen Orientation - 8° universal Trim Section Resolution - 1 to 1500μm Sectioning Range - 1 to 1500μm Specimen Size -    45 x 45 mm

Leica EM UC7, high quality ultramicrotome for precise room temperature sectioning

The Ultratome provides high quality sectioning of specimens for light, electron, and atomic force microscopy examination. Leica EM UC7 FC7 Brochure

Eucentric movement of the stereomicroscope observation system with patented designated positions for specimen approach, for glass and diamond knives.

In addition to the standard LED illumination for top light and backlight and transmitted light, the LED spot illumination offers a focused light beam to enhance observation, e.g., for cleaning the knife edge and during cryo-sectioning.

The user can walk away from the instrument during trimming; the combination of the fully motorized knife stage and patented AutoTrim function completes and then stops the trim automatically.

Easy-to-learn, fast operation via touchscreen control and displayed hints.

Data transfer for reporting user, specimen, knife and storage parameters provides an electronic, paper-free log file.

The operator recognition system makes it easy for multiple users to use the same instrument. Up to 100 different user/specimen/ knife profiles can be set.
