ABSTRACT:
A multiwell tissue culture assembly for culturing cells comprising a plate and a lid. The plate includes a plurality of wells for receiving liquids therein 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. 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. 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.
