ABSTRACT:
A multiwell tissue culture assembly for culturing cells comprising a plate and a lid. The plate includes a plurality of wells for accommodating a cell culture insert and the lid includes means for varying the gas diffusion into and out of the assembly and for substantially minimizing biological contamination of the cells being cultured in the cell culture insert. The means for varying the gas diffusion is a gas permeable membrane provided in an opening in the lid and a removable thin impermeable film label is provided for selectively occluding passage of gases through the gas permeable membrane.
