The present invention describes several embodiments of a device that allows for the supporting, storage and deployment of large surface area thin film solid phase microextraction (TF-SPME) chemical samplers from within a sample fluid carrier. The utility of said supporting device originates from the process by which the extraction surface is stabilised within a sample carrying fluid for the extraction of chemical molecules from said sample carrying fluid. The device is also characterized by having a seating cavity, and moving mechanism or cap that can switch the supported TF-SPME chemical sampler between an open, sampling position or closed storage position.
