Designed for short-term handling and storage of samples that require multiple access to wells by pipet tips or robotic probes. Automation compatible. A precut “X” over each well creates bendable flaps that provide sample access without coring or adhesive fouling, then partially reseal multiple times after piercing to minimize evaporation. 96 printed circles aid in the alignment of the film to the plate; alpha-numerics identify each well. Features two end-tabs with perforations for ease of handling, application and removal.
