Tri-Tech Forensics FTA Micro Card, 1 Circle, 100 Pack

Designed for the collection, transportation, storage and purification of nucleic acids from whole blood and buccal cells/saliva, each FTA Card has an integral cover sheet which protects the sample and permits the card to stand on its own while drying. The FTA Indicating Card changes from pink to white when the card comes in contact with the sample. The dye washes out during processing and does not inhibit analysis or transformation.
