A multi-layer film consisting of a top pierceable clear polyethylene film and a white polypropylene sub-layer with 96 circular areas void of adhesive. Designed for short-term storage and robotics applications in order to minimize evaporation and reduce cross-contamination. The adhesive-free zones are 9mm on centre to facilitate multi-channel pipetting without adhesive fouling of pipet tips or robotic probes. The white sub-layer aids in the alignment of the film to the plate. Offers excellent chemical resistance; samples have minimal contact with adhesive. Features two end-tabs with perforations for ease of handling, application and removal.
