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 packed in tamper evident bags of 25.

These films are 240 µm thick black vinyl with adhesive for use with 96-well, 384-well and 1536-well black microplates. They fit within the edges of raised rim plates and may be applied to either the plate top or bottom. The light blocking and absorbing properties of these films make them ideal for reducing stray light and crosstalk in fluorescence applications and for protecting light-sensitive samples in storage.
