Managing Large Volume, Single Use Disposables
This chapter will describe the process for determining the feasibility of applications for single use disposable bags in a typical large scale biopharmaceutical facility with bioreactor working volumes of 10,000 liters or more. The article will include an overview of single use disposable bags, an overview of an applicable biopharmaceutical facility, and potential applications within the facility. The applications will include cell culture bioreactors; solution preparation in media preparation and buffer preparation; solution transfer from the preparation area into the process area; solution storage in media storage and buffer storage; purification; and dispensing raw materials from the dispensary into the process areas. Each application will be evaluated with case studies as examples. The case study will include pros and cons and cost evaluation with feasibility and recommendations. The feasibility of each application will be evaluated relative to process efficacy, cost effectiveness in comparison with fixed stainless steel equipment, required manipulations, and ease of operation. Facility design requirements will be described to incorporate the single use disposable bags into the operation.
