The cultivation of
cells as mass cultures has become increasingly important over the past
few decades and has led to further developments of high-quality
products. This includes items such as roller bottles which are used for
the production of virus vaccines or recombinant proteins used for
therapeutic approaches. CELLMASTER™
roller bottles are made from polystyrene (PS) or polyethylene
terephthalate (PET). These materials, like those used for the screw caps
(HDPE) and the hydrophobic membrane (PET/PTFE) of the filter screw
caps, comply with the quality standards of the U.S. Pharmacopoeia. The
complete end product is USP Class VI certified. All roller bottles are
sterilised by irradiation.
