Facilities & Equipment

As of March 2016, the Wiener Laboratory has been operating in its new, free standing, three storied building. The new laboratory has sufficient and proper storage for its permanent comparative collections and temporary storage units for materials to be analyzed, state-of-the-art laboratories for sampling and analyzing organic and inorganic materials, new analytical equipment and designated spaces for study and consultation (carrels and offices, library and computing facilities, seminar and meeting rooms), and administrative and support offices.

Detailed Equipment Inventory

- SEM/EDS: The Laboratory has recently acquired a low vacuum Scanning Electron Microscope, JEOL, JSM-IT300LV, followed by Energy Dispersive X-Ray Microanalytical system, Oxford Aztec STD X-act. Versatility and high resolution across the magnification range of 5X - 300,000X are the hallmarks of the JSM-IT300LV. The system extends vacuum pressure range to 650 Pa. In low vacuum mode, this capability enhances SEM imaging versatility for samples that are wet, oily, outgas excessively or are non-conductive without pretreatment. The large vacuum chamber accommodates samples up to 300mm in diameter and 80mm in height. The system will be fully operational in May 2016.

- FTIR: A Fourier Transform Infrared Spectrometer, Thermo Scientific Model Νicolet iS5, with a spectral Range 7800-500 cm-1 is available for identification of materials and their characterization.

- pXRF: a handheld X-Ray Fluorescence analyzer, Bruker TRACER III SD, is available for determining the provenance of objects of cultural value or obtaining elemental data for geochemical survey.

- 3D Laser Scanner: The Laboratory has recently acquired a NextEngine 3D Laser Scanner HD for capturing 3D geometry with rich full color texture of bone and archaeological objects.

- Microscopes: The Laboratory has six Leica research grade microscopes:

  1. DMILM Inverted Microscope for material control with two lamp housings for brightfield and fluorescence work; at total magnifications 50X, 100X, 200X, and 500X.
  2. M10 Sterozoom microscope with optional transmitted light base, long swinging arm for large objects and total magnification ranging from 8X to 80X.
  3. Laborlux 12PolS polarizing light microscope for analysis of samples in thin section, with reflected light capability for opaque materials and ores at total magnifications 50X, 100X, 200X, 400X and 500X.
  4. Laborlux 11PolS polarizing microscope for analysis of samples in thin section at total magnifications 40X, 100X, 400X and 500X.
  5. DMLM industrial microscope with vertical stage adjustment up to 110 mm for incident and transmitted polarized light microscopy in brightfield and darkfield at total magnifications 50X, 100X, 200X, 500X and 1000X.
  6. DM2700P polarizing light microscope for petrographic analysis at total magnifications 12.5X, 50X, 100X, 200X, 400X and 500X.

All the instruments include digital photographic capabilities. The lab has also a Dino Lite digital microscope and a Unitron Metallograph (ME-2029) microscope.
