Germany-based Greiner Bio-One plans to launch CELLMASTER Roller Bottle product portfolio, designed to fulfill different requirements for the production of virus vaccines or recombinant proteins used for therapeutic approaches.
The new roller bottles are made from high grade polystyrene (PS) or polyethylene terephtalate (PET) and feature a two-phase blow-molding procedure, which rules out the risk of liquid leaking from a faulty seam.
The bottles with a smooth or ribbed surface range in size from 850 cm² to 4720 cm² growth area and are available either with standard or filter screw caps.
The redesigned screw caps offer a better grip with easy opening and shorter threads on the bottle-neck makes it faster and easier to handle as well as more robotic friendly.
Greiner Bio-One said the hydrophobic capillary pore filter membrane with a defined pore size of 0.2 µm will guarantee optimal protection against contamination while providing a high gaseous exchange rate which enables a mass cultivation of cells using bicarbonate buffer and CO2.
Greiner Bio-One provides product manufacturing, distribution logistics and product application support to clinical laboratories performing IVD testing, research laboratories at universities, startup companies, and to the world’s largest pharmaceutical and biotechnology corporations.
