Injection Circuit Feeding the Bacterium Bioplast

The injection circuit appears as a narrow, transparent feed line running between the refinery's central control panel and the bioplast reactor. Its surface is marked with faint glow pulses from the bacterial flow, and a series of manual override dials allow operators to adjust nutrient and oxygen feed rates to the bioplast colony. Thawn and Fenner manipulate these dials during the Doctor's explanation, demonstrating their control over the system.
