Evergreen FTKfecal transport kits offer the three most commonly used preservatives: 10% buffered formalin, zinc sulfate (ZnSO4) PVA, and SAF (sodium acetate formalin). Mercuric chloride (HgCl2) PVA has been discontinued for environmental reasons.

Each of the three preservatives is available as a single vial. Zinc sulfate PVA is also available with 10% buffered formalin as a dual vial kit. The 10% buffered formalin is recommended for wet mount and concetration procedures, and the polyvinyl alcohol (PVA) fixatives are recommended for permanent trichrome staining.

Single vial kit with sodium acetate formalin (SAF) are appropriate for wet mount and concentration procedures, as well as for permanent staining using modified iron-hematoxylin stain with carbol fuchsin. (Ask our Customer Service Department for supplemental literature detailing this technique).

Choose 15 ml vials (each filled with 9 ml preservative).

TWO INTEGRATED SYSTEMS

15 ml vial kits may be used directly with Evergreen's FPCFecal Parasite Concentrator, and 30 ml vial kits may be used directly with Evergreen's FPC JUMBOFecal Parasite Concentrator. Only Evergreen Scientific and its authorized distributors can offer not one but two integrated systems to collect, preserve, transport, and process fecal specimens for ova and parasite studies.

SIMPLE AND EASY TO USE

Easy-to-follow directions in English and Spanish direct the patient in collecting and preserving the specimen. Each vial includes a convenient, in-cap spork for scooping and mixing, and fill lines indicate correct volume levels and ensure a proper sample/preservative ratio. Leakproof caps help prevent accidental spillage.
