Each vessel can be used only once, though there are no limits on the duration of the experiment.
Each culture vessel is gamma sterilized and individually packaged (heat sealed) for immediate use upon opening. All disposable vessel bioreactor systems include four individually wrapped HARV culture vessels (10 mL or 50 mL), except the RCCS-8D and RCCS-8DQ, which include 8 vessels.
They can be operated at the same speed of rotation for all vessels or 4 independent speeds for 4 or 8 vessels.
