Titer-Tops prevents sample evaporation, well to well contamination, external contamination and sample spillage. Titer-Tops are made from 4.4 mil polyethylene film with an FDA approved non cytotoxic acrylic adhesive.

Each pre-cut rectangular sheet is 6 x 3.25" with a paper liner. The center section of the liner measures 5 x 3.25" and once it is peeled off it leaves two hand-grip extension tabs on the two ends. These tabs allow for easy application of the Titer-Top to the plate. The acrylic adhesive is waterproof, solvent resistant, and compatible with all plastic microtiter plates. Titer-Tops will stay in place even when exposed to 100% humidity and temperatures ranging from -40 to 100 °C.
