Precision cut to a smaller dimension to seal a single 8-well row of a 96-well plate or an ELISA strip-well plate. Each sheet contains 8 FilmStrips on a continuous backing liner for ease of use. FilmStrips can be used to selectively cover one row of a plate to prevent accidental pipetting or to re-seal rows that have been pierced. 2.0mil polypropylene film features good clarity and easy handling. Specially formulated adhesive provides an excellent seal to minimize evaporation, reduce cross-contamination and prevent spillage. Removes easily and cleanly from plate surfaces.
