Easylift® is a self-adhesive tape that is designed to allow the retrieval and easy characterisation of particles of interest. In its typical mode of use, its adhesive is brought into contact with a surface. The tape is then removed from that surface and adhered to a glass microscope slide to form what is known as a tape lift. Particles of interest from that surface are then characterised in situ in the tape lift using one or more of the techniques that are listed in item 4, below. This allows the characterisation, classification and quantification of particles of interest within the protective environment of the tape lift. This removes the need to expose those particles to the possibility of contamination or loss during storage, transport or analysis.
