Polyester films are a great general purpose seal; ideal for sample protection and elimination of well-to-well sample cross contamination. The acrylic adhesive offers a strong bond that seals tightly on polypropylene and polystyrene plates.
This seal is ideally suited for short term storage, Elisa assays, prevention of sample loss, and general lab usage.
The paper backing of this film is scored on both ends to allow for two handed (precise) placement on the plate.
