Hello! I am a newcomer I plan to culture cells in a small pressurized chamber. Please take a look at the picture attached My design: -pump gas into the chamber and close the valve afterwards -the pressure meter will keep track of the pressure and ensure that there is no leakage -the chamber has to be transparent and bio-compatible (eg. PDMS) -it should consist of 2 pieces: cover and base. After putting the cells in, it will be sealed -it is to be put under microscope for live cell imaging the shape would be cylindrical, with height <3cm and radius <5cm I want to apply a pressure of 100-500kPa. Is that possible using PDMS as the material? If not, please suggest a suitable material.
