Materials Of Construction For Biopharmaceutical Water Systems
Stainless steels are uniquely qualified for bioprocessing applications not only because of their long service life, availability, and fabricability, but also because they are non-corroding, non-contaminant, can be polished to very smooth finishes, are strong and rigid, can withstand heat and chemical sterilization treatments, and are easily welded.

Effect Of Sterilization On Mechanical Properties Of Silicone Rubbers
Silicone rubber is widely used in the pharmaceutical industry where sterilizability is an essential requirement for all fluid transfer equipment. Pharmaceutical products must be sterilized frequently and repeatedly by high level energy and/or chemical vapor in order to eliminate bacterial surface contamination.
