The Mastersizer 3000 laser diffraction particle size analyzer (external link)

The mastersizer 3000 uses laser diffraction techniques to measure particle size distribution in the range between 0.01 μm and 3.5 mm. At EARTHLAB, dispersal units for small volume wet samples (manual Hydro SV), large volume wet samples (automated Hydro LV) and dry samples (Aero S) are available, allowing analysis of wet and dry samples at a wide range of sample sizes.

Malvern Morphologi G3 particle analyzer (external link)

The Morphologi G3 measures particle size and shape of dry and wet samples using static image analysis. It can handle particles in the range from 0.5 to 1000 μm dispersed as dry powder on a glass plate or as wet samples on microscope slides or in a cell. The morphology G3 has bright-field diascopic and episcopic, dark-field episcopic as well as white light sources, and produces information on particle size, shape, transparency, count and location in the dispersed sample.

In addition to the instruments outlined above, EARTHLAB sediment also has a dedicated sample preparation laboratory, equipped with tools for handling and sub-sampling sediments such as sieves, light microscopes, muffle furnaces, drying cabinets, a freeze-dryer, an ultrasonic bath etc.
