Leica UCT Ultracut Ultramicrotome Microscope

This instrument is designed for extremely precise cutting of resin embedded biological specimens. It achieves consistent high quality ultra-thin sections (40-100 nm) for transmission electron microscopy, or semi-thin sections (1-2 µm) for light microscopy. It features a continuous feed range from 0 to 2.5 µm and has adjustable cutting speeds of 0.1 to 50 mm/sec. The system consists of a control box with power cord, a microtome sectioning unit, and a microscope assembly with AO Stereostar 570 zoom body (0.7X – 4.2X) with attached 10X eyepieces. It has a 6V, 10W halogen illumination system. Services provided by TEM staff include: Training in transmission electron microscope operation; Assisted and unassisted use of the electron microscope; Tissue processing and resin embedding of specimens for TEM; Ultrathin sectioning of resin embedded specimens; Negative staining of small particles (e.g. purified viruses and proteins).
