The only thing that can be considered to be sterile is water that
has been tested for sterility. All Millipore systems are
designed to remove contaminants but this does not result in
sterile water. I would expect your tissue culture media is sterile
because it is either autoclaved or filtered afterwards.
If your Millipore system is not well looked after you
might be surprised by how high the bacterial count can get
especially if the water is kept in a storage tank.
