Cell science hardware is currently available for lease or production by SHOT(R). The SHOT Avian Development Facility (ADF) is a single middeck locker experiment containing two carousels capable of rotating at variable g. Each carousel accommodates 18 40-ml vessels that can be adapted for the cultivation of avian or reptilian eggs, small invertebrates, zebra fish, small plants, seeds, spores, cells or tissues. Cellcult Cassettes contain a small (20-50 ml) rotating cylindrical culture vessel with feed media reservoir, pumps, waste bag and sample collection bags. Cultures can be rotated, perfused, fed, aerated and sampled automatically or on remote command. Fluid Processing Cassettes contain a flexible combination of feed, culture and fixative bags with valves and pumps programmable for various feeding and fixing protocols. Dynacult Cassettes contain a cylindrical bioreactor with differentially rotating walls, pumps and valves for feeding and sampling, and pH and oxygen measurement. All cassettes are doubly contained and are accommodated by a computerized, thermally controlled processing facility, the Advanced Space Experiment Processor, which processes three cassettes, or the Biotechnology Thermal Environment Carrier, which holds up to six cassettes.
