Electron Microscopy Center
The Electron Microscopy Center provides electron and ion microscopy for all researchers in the UT system, ORNL, other institutions, and external partners.
The facility is equipped with TEM, SEM/FIB, and modern sample preparation for soft and solid materials. The facility is available on a self-use basis and for service requests.
TEM: Zeiss Libra200
The transmission electron microscope (TEM) at IAMM is located in SERF 101. This TEM is used for atomic and micro-scale investigations in materials science of solid and soft materials (polymers). It is also used for diagnostics in medical science and in research of biology and agriculture. Most applications are in imaging small features in cells or materials and tomographic investigations through tilt series at liquid nitrogen temperatures within the TEM. This microscope was specifically designed to enable chemical investigations on the atomic length scale. We can also map surface plasmons and band gaps with sub-nanometer resolution.
FIB: Zeiss Auriga Crossbeam FIB/SEM
The Zeiss Dual Beam FIB/SEM instrument is located in SERF 101. It is not only used as high-resolution Scanning electron microscope but can be used together with an scanning focused ion beam. Uses include TEM sample preparation and micro-machining. We can also slice and image successively to get tomographic 3D images of small objects from cells to proteins and nano-wires.
The sample prep lab at IAMM is equipped for standard sample preparation for transmission electron microscopy. The following instruments are available in SERF 101. There is additional equipment available for biological and polymer sample preparation.
Plasma Cleaner – Fischione
This instrument provides plasma that allows us to clean sample holders of the TEM and FIB and the samples themselves. An oxygen plasma is ignited and the cleaning process occurs at the periphery of this plasma.
Precision ION Mill – Gatan PIPS
This instrument thins TEM samples without contact by bombarding it with fast (1-6kV) Argon ions. This ion mill produces a small hole in the TEM sample with the rim thin enough to be electron transparent in the transmission electron microscope
Dimpling Grinder – Fischione
A thin section of a sample is placed at the table of this dimpler. The grinding wheel and the table rotate. The sample is thereby thinned in a small dimple to a few tens of micrometer.
Leica Ultramicrotome EM UC7
This piece of equipment provides easy preparation of semi and ultrathin sections, as well as perfect, perfect smooth surfaces of biological and industrial samples for TEM, SEM, AFM and LM examination. It also has an attachable cryochamber for materials too soft to be sectioned at room temperature.
Leica Mill EM TRIM2
This is a high-speed milling system with an integrated stereomicroscope and LED ring illuminator for trimming of biological and industrial samples prior to ultramicrotomy.
Allied Multiprep Polisher
The MultiPrep System enables precise semi-automatic sample preparation of a wide range of materials for microscopic (optical, SEM, FIB, TEM, AFM, etc.) evaluation.
Allied Techcut 4 Slow Speed Saw
This is a low-speed saw excellent for cutting smaller, delicate samples that cannot tolerate excessive friction and heat caused by high speed sectioning.
Plunge Freezer – Gatan
This plunge freezer enables to freeze TEM samples quickly to liquid nitrogen temperatures. The environmental chamber allows to first equilibrate the sample to a controlled hydration state, and then cool it down fast to cytostatic temperatures for investigation in the cryo-TEM.
Assisted help is billed in addition to the regular instrument rate. Rates for instrument time indicate self-use. Any operation of the instrument by staff will incur an additional charge for staff assistance. If staff assistance will be required that time must be booked in advance of reserving instrument time. Please contact Neal Evans for assistance requests.
Rates include usages of Includes usage of ultramicrotome, multiprep, ion polishing system, dimpler, diamond saw and consumables except diamond lapping paper. Diamond lapping paper is sold by the facility at cost price.
