TopSeal-A 24, Clear Self-Adhesive Topseal for 24-well Microplates

PerkinElmer offers a variety of plate seals. TopSeal^™ is a range of plate seals that are applied to the top surface of the plate, and are used to prevent evaporation or radioactive contamination during assay incubation steps and/or plate reading measurements. TopSeal-A can be left on the plate during luminescent, AlphaScreen^®, AlphaLISA^®, and radiometric measurements. TopSeal plate seals have spectral properties that may interfere with other types of assay measurements (absorbance assays, colorimetric assays, fluorescence assays). For these types of assays, you should compare the plate measurement with and without a TopSeal plate seal to test for interference.
