23A00U197: Gas permeable film for culture growth, cell assays, and cell screening. A 125Âµm thick porous seal formed by layers of non-woven rayon/acrylic fibers. This hydrophobic and gas permeable layer has average pore size from 10Âµm to 40Âµm, is backed with a medical-grade (non-cytotoxic) acrylic adhesive, and is suitable for tissue, cell, and bacterial cultures. Non-woven rayon/acrylic allows uniform rates of gaseous exchange (O2 and CO2) across the membrane for all wells; promoting contaminant free growth of cells. Film is removable, not reusable. Strong adhesive minimizes cross-contamination, spillage and evaporation; covered plates can be inverted and agitated without sample leakage. Do not store plates inverted. Dimensions: 136.00 x 82.00mm (with tab removed) Recommended for temperatures from -20Â° to +80Â°C All ILP sealing films are manufactured in a cleanroom environment. They are tested and certified on a lot to lot basis to be free of RNase, DNase, DNA, and Pyrogen contamination.
