EQUIPMENT & ACCESSORIES CATALOG EDITION IV CRYO-SEM & CRYO-FIB/SEM PREPARATION SYSTEMS


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.


Stable emulsion of a hydrophobic polymer


This image illustrates a stable emulsion of a synthetic liquid polymer dispersed in an aqueous continuous phase.


Latex Latex particles are very electron beam sensitive, so cryo-SEM is an ideal method for their observation


Dendritic Ice Crystals


If it is cooled slowly, water forms dendritic ice crystals. These can have a variety of branching patterns — the complexity of which depends upon cooling rate. Arms extend from the main body of the crystal at an angle of 60°. Some, such as the one illustrated, resemble the arms of a snowflake. Bar: 2um
