Roller bottles made of polystyrene or PET range in size from 850 cm² to 4250 cm² growth area and are available either with standard or filter screw caps.
The safety screw cap enables a tight closing and contamination-free cultivation. The filter screw cap contains a membrane with a pore size of 0.2 μm guarantees optimal protection against contamination. It provides a high gas exchange rate which enables a mass cultivation of cells using e.g. bicarbonate buffer and CO2.
The product range includes a short and a long form, labelled as X and XL, accordingly. Both sizes are available with a smooth or radially ribbed surface. The ribbed design increases the growth area of the roller bottle without changing space requirements. All roller bottles are sterilized by irradiation according to validated procedures (ISO 11137). Endotoxin testing is conducted in accordance with USP 85 with a tolerance level of 0.03 EU/ml.
