Cryo-SEM Applications Zoological


Botanical


Frozen hydrated aphid


In comparison with the critical point dried aphid, this image shows that there is no distortion of the abdomen nor any other parts of the aphid following freeze drying.


Fungi


Pollen of cactus Zygocactus truncatus Germinating pollen grains of Zygocactus truncatus.


Geological Maize root starch granules


Baker’s yeast (Saccharomyces cerevisiae)


The specimen was rapidly frozen in nitrogen slush, fractured and coated with 4nm of platinium (Pt). 10nm yeast cell transmembrane particles (in hexagonal arrays) can be observed.


Cryo-DualBeam


Wax crystals in gas oil


When cooled to a temperature below about 2°C, the waxes in fuel oils such as this tend to crystallize out. Wax crystal size and shape can be varied by altering the rate at which the oil is cooled.
