Specimen Preparation

• Open top, modular design.
• Stainless steel cooling chamber.
• Chamber temperature regulation variable from -10°C to -35°C.
• Rotary Microtome with backlash and maintenance-free cross roller bearings in stainless steel.
• Electro-mechanical feed system. Motorized coarse feed in two directions with three speed selections.
• Section thickness setting from 1 to 100 microns. Trimming thickness setting from 5 to 500 microns.
• Specimen retraction during the return stroke with optical indication.
• Horizontal feed range 28 mm. Vertical cutting stroke 60 mm.
• Max. specimen size 75 x 55 mm
• Limit indication and automated switch off at front and rear limits of horizontal travel.
• Automatic approach system for exact and safe approach of specimen towards the knife edge 
• Section counter and indication of sum of section thicknesses with reset button with indication of remaining travel.
• Standard Operating Procedure: Download HM550 Cryostat SOP 

The Leica EM UC7 prepares excellent quality semi- and ultra-thin sections, as well as the perfectly smooth surfaces required for LM, TEM, SEM, and AFM examination.

Features

• Cutting thickness: 1 nm to 15 μm | Cutting speed: 0.05 to 100 mm/sec
• Stereomicroscope observation system with patented designated positions for specimen approach, for glass and diamond knives.
• LED illumination for top light and backlight and transmitted light. LED spot illumination offers a focused light beam to enhance observation.
• 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 allow multiple users to use the same instrument. Up to 100 different user/specimen/knife profiles can be set.
