A 140 µm thick hydrophobic porous rayon sealing film including medical-grade adhesive for tissue culture plates, bio-blocks, and 96-well plates where gas exchange is necessary for cell or bacterial growth. AeraSeal sealing films minimize cross-contamination, spillage and evaporation. They allow uniform air and CO2 exchange for all wells, unlike plate lids which favor exchange for wells near the plate edges. Dimensions: 82.6 by 142.9 mm for standard-size tissue culture plates.

• non-cytotoxic, highly gas permeable
• easily pierceable with pipet tips or pipets for sample recovery
• recommended for temperatures from -20 °C to +80 °C
