10% FORMALIN FIXATIVE IN WATER

This preservative is a good overall fixative and will fix both ova and cysts although it only preserves the internal morphology of the cysts for up to 6 months, after which the cytoplasm of the organism becomes granular with poor nuclear definition.

 SODIUM ACETATE ACETIC ACID FORMALIN (SAF)

SAF fixed material is suitable for direct examination, concentration (Formalin/Ethyl Acetate) and permanent staining.

.

MERTHIOLATE-IODINE FORMALIN (MIF)

Formol-Ethyl Acetate concentration methods can be performed on samples preserved in MIF.

POLYVINYL ALCOHOL (PVA)

This method will preserve ova, larvae and trophozoites well, but cysts may show some distortion.  However, some ova and cysts do not concentrate well when preserved in PVA.
