Continuous flow photoreactor

A photoreactor, comprising:

• a first housing including a reactor inlet port, a reactor outlet port, and a length of reactor tubing disposed inside the first housing and fluidically coupled to the reactor inlet port and the reactor outlet port;
• a second housing defining an inner volume and including an inlet port and an outlet port, the second housing separated from the first housing by a separation distance of at least about 5 mm;
• a light source disposed in the inner volume of the second housing and configured to emit light toward the reactor tubing;
• and
• a length of temperature control tubing disposed in the inner volume of the second housing, the length of temperature control tubing configured to transport a heat transfer fluid that draws heat from the light source.

A photoreactor, comprising:

• a first reactor flow system including a first reactor inlet port and a first reactor outlet port coupled to a first housing, and a first length of reactor tubing fluidically coupled to the first reactor inlet port and the first reactor outlet port and disposed inside the first housing;
• a second reactor flow system including a second reactor inlet port and a second reactor outlet port coupled to a second housing, and a second length of reactor tubing fluidically coupled to the second reactor inlet port and the second reactor outlet port and disposed inside the second housing, the second housing separated from the first housing by a separation distance of at least about 5 mm;
• a lighting system disposed between the first reactor flow system and the second reactor flow system, the lighting system including a light source configured to emit light toward the first reactor flow system and the second reactor flow system;
• and
• a temperature control system disposed and configured to cool the lighting system, the temperature control system including a length of temperature control tubing disposed in a third housing.
