Racked Optical Sensitive PCR Sealing Film

Short Description:

Optical sealing film is a transparent sealing film that uses a gel and is widely used in experiments with 96/384 well plates such as: PCR, qPCR, ELISA, cell culture, long-term storage, automated workstation processing and almost all other experiments. Its main function is to ensure an intimate fit of the sealing film to the 96/384 well plate to prevent evaporation of the liquid.

The correct way to apply the optical sealing film is as follows

1. Remove the single sheet of sealing film or sealing foil from the self-sealing bag and reseal the bag to maintain the enzyme-free environment within.

2. Hold the sealing film or foil with the backing side up. Fold the end tab down at the tangent line of the backing.

3. If the product being used is a single end-labelled sealing film or foil, partially remove the liner, then anchor the sealing film or foil to the board so that it is sealed over the entire board and proceed to remove the liner. This method eliminates curling and rollback from the sealing film or foil.

4. If using a product with two end tabs, peel the centre liner in a continuous smooth manner. Slow peeling of the liner will reduce curling to a large extent. Take care not to touch the adhesive surface of the film.

5. Using both hands, grasp the white part of the two ends and lower the film onto the aperture plate.

6. Use the platen to slowly scrape and press the sealing film or foil to seal it to the plate. This step should be performed at least twice, horizontally and vertically. Applying sufficient force is essential to obtain a good seal.

7. Scrape the platen along all outer edges of the perforated plate at least twice to ensure firm and consistent pressure is applied.

8. Inspect the plate after sealing to confirm a tight bond between the film/foil and the plate.

Note: The optical sealing film or foil should not be wrinkled; if wrinkles are observed, the plate has not been sealed correctly. Also note that the sealing film or foil should not extend upwards onto the side walls of the plate. This may occur with flat panels with raised edges due to incorrect positioning of the sealing film or foil on the panel, or if the joints at the ends have not been removed. Verify that the paste marks around each hole and that the entire surface of the plate (including the perimeter) is sealed.
