Used 13mL Cell Culture Microbioreactor System. Manufactured by Sartorius, Model #Ambr15. Automated microscale bioreactor platform designed for parallel operation of 24–48 single-use 10–15 mL vessels (Ideal working volume is 13 mL), providing controlled stirring (300–1500 rpm), automated gassing with CO2/N2/O2, per-vessel optical DO and pH measurement, air-based or chilled temperature regulation, and robotic liquid handling using 1 mL and 5 mL tips for media fills, feeds, sampling, and pH/base adjustments. Fluorescence sensor spots read every 90 seconds, programmable PID control for DO and pH, configurable process steps (scheduled or conditional), and supports a range of labware including deep-well reagent plates and standard sample plates. The system is intended for research-scale culture, screening, and process optimization of non-hazardous eukaryotic cell lines, providing bioreactor-like control and throughput in a compact microscale format. Serial #R5-609, built 2022.
