High Resolution Transmission Electron Microscope (HRETM)
HRTEM - JEM-2100F (JEOL)
The JEM-2100F is an advanced Field Emission Transmission Electron Microscope featuring ultrahigh resolution and rapid data acquisition. The JEM-2100F is a next generation TEM that simplifies atomic level structural analyses in biology, medicine, and materials sciences as well as the semiconductor and pharmaceutical industries.
The JEM-2100F has been developed to achieve the highest image quality and the highest analytical performance in the 200kV class analytical TEM with a probe size under 0.5 nm. The new side-entry goniometer stage provide ease of use tilt, rotation, heating and cooling, programmable multi-point settings--all without mechanical drift. The JEM-2100F at ODU-ARC is equipped with an Oxford Xplore SDD detector, a 11-megapixel Gatan SC1000 ORIUS CCD camera, and a Gatan 626 single tilt liquid nitrogen cryo transfer holder.

VEECO Dimension 3100
The Dimension 3100 AFM is an instrument capable of imaging specimens with a horizontal and vertical resolution down to a fraction of a nanometer. The instrument works by measuring the deflection produced by a sharp tip on micron-sized cantilever as it scans across the surface of the specimen, which provides users the ability to characterize the surface roughness of materials and nanofabricated structures. Sample sizes that can be handled by the instrument range from small pieces to 4-inch diameter wafers.
Scanning Modes:
- Tapping mode
- Contact mode
UV-Vis Spectrometer
LAMBDA 45 UV/Vis System (PerkinElmer)
LAMBDA 45 UV/Vis Spectrophotometer from PerkinElmer can be used for measurements on liquids, solids, pastes, powders samples and regulatory tests requiring variable bandwidths and highly scattering light samples. The additional pre-monochromator reduces stray light by a factor of 2, providing optimum performance for turbid and light-scattering liquid samples, such as biological solutions and suspensions.
Features:
- True double beam operation for very high stability, higher accuracy and reproducibility
- 1 nm resolution and low stray-light design easily passes all pharmacopoeia and regulatory performance tests
- Widest range of reproducible and robust sampling accessories to simplify and speed your analysis, whatever your sample
- Pre-aligned Deuterium and Tungsten-halogen lamps for increased uptime
- Choice of UV WinLab software to simplify analysis from sample entry to report generation
