Buehler IsoMet 4000 Precision Saw

Frantz Magnetic Barrier Laboratory Separator specifically designed for separating minerals according to their magnetic properties. It is a central piece of equipment for geochronological projects to separate minerals with similar densities (e.g., different pyroxenes, olivine from pyroxene) which, cannot be separated using heavy liquids (methylene iodide and bromoform can be used whenever needed). Both methods are often necessary to use to achieve ideal mineral separation prior to tedious hand picking to obtain pure mineral fractions prior to chemical dissolution and processing for isotopic measurements.

Olympus SZX16 Stereomicroscope with segmented LED ring light, and accessories for transmitted and polarized light - available in the Class 10,000 mineral separation room to observe and proceed with the hand picking of small crystals separated from planetary materials, and remains located with the clean preparation laboratory.

Thermo Scientific Isotemp gravity-driven convection oven - used for carefully drying samples, mass spectrometer parts, and dissolving rock and mineral samples in heated sealed devices (Parr bombs). This is crucial to dissolve accessory minerals resistant to hot plate dissolution such as zircon or chromite using sealed vessels placed within an homogeneously heated oven to ensure a proper temperature and avoid over heated vessels.

Buehler IsoMet 4000 Precision Saw - designed for cutting various material types with minimal deformation. One micron sample positioning allows for precise sectioning of specimens and user selectable feed rate allows for ultimate versatility. This will be used for extremely precise cuts of precious samples such as meteorites.

Sample Storing Facilities

Sample Preparation Laboratory

Sample Preparation Laboratory

A nitrogen generator and storage cabinet are available for storing sensitive meteorite research specimens in a clean dust-free and dry environment to avoid contamination, alteration and degradation of meteorites such as iron-metal-bearing meteorites (irons, chondrites) and organic-rich chondrites. The cabinet is located within the secured Western meteorite collection storage room for storing of the most sensitive research meteorite specimens until needed for research.
