A 139.7 µm thick hydrophobic porous film with medical-grade adhesive for tissue culture plates, bio-blocks, and 96-well plates where gas exchange is necessary for cell or bacterial growth. These rayon films minimise cross-contamination, spillage and evaporation. They allow uniform air and CO₂ exchange for all wells, unlike plate lids which favour exchange for wells near plate edges. Sterile product is packaged in tamper evident bags of 25.

• Non cytotoxic, highly gas permeable
• Pierceable using pipette tip for sample recovery
• Recommended for temperatures from −20 to +80 °C

Each film L×D: 142,9×82,6 mm (5⁵/₈x3¹/₄") for standard size tissue culture plates.
