Rapid cryoimmobilization of biological specimen has many advantages over traditional processing methods.
performs freeze substitution and allows low temperature embedding and polymerization of resin.
It is particularly useful in the rapid preparation of fine-grain TEM specimen support films by carbon evaporation, or the evaporation of a variety of metals in the preparation of shadow-cast specimens.
Imake a carbon film surface negatively charged (hydrophilic) which allows aqueous solutions to spread easily.
Microwaves have been employed to facilitate faster solution exchange for TEM biological sample preparation.
provides easy preparation of semi and ultra thin sections of biological samples for TEM and LM examination.
prepare glass knives for ultramicrotomy
