ABSTRACT:
The present invention is directed to a carrier for retaining and transferring filtration devices, as well as to filtration devices configured for placement in the carrier. The carrier generally includes a tray having a plurality of filter seats along with a plurality of holes extending through the tray. Each filter has a release liner that is removably secured to a pressure sensitive adhesive on the filter, and this release liner also contains a tab that extends through one of the holes in the tray and is permanently bonded to the bottom side of the tray.In use the filters can be removed from the tray by manual or automatic means. During the removal process the release liner separates from the pressure sensitive adhesive on the filter and is retained on the tray. In certain implementations the release liner contains two portions with an adhesive on them—one portion in contact with the filter and one portion in contact with the tray—and these two portions are separated by an area of the release liner that does not contain adhesive.
