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 a plurality of openings in the lid and a plurality of removable thin impermeable film labels are provided for selectively occluding passage of gases through the gas permeable membranes. The means for minimizing biological contamination of the cells being cultured is a sealing material located in the lid and means for removably securing the lid and the plate together whereby the sealing material is compressed between the lid and the plate.
