Our MEA lids have been specifically designed for our HD-MEA probes.
They are made of polytetrafluoroethylene (Teflon™) and have a transparent membrane (FEP: fluorinated ethylene-propylene) stretched across the top.
The membrane allows the diffusion of gases, but limits evaporation, thus reducing the need for a humidified atmosphere, while also preventing culture contamination. Caps can be sterilized and are available with just the FEP membrane (BC100A; left figure) or equipped with a perfusion inlet and outlet (BC101A; right figure).
