1. A fluidic device comprising:
a microfluidic cartridge comprising a substrate, wherein the substrate comprises at least one reaction chamber;
a cartridge holder configured to form an air channel between the cartridge holder and the microfluidic cartridge;
an air inlet duct configured to flow air into the air channel to provide fluid flow that creates a thin fluid film in thermal communication with the substrate;
a first heating element; and,
a second heating element;
wherein the first heating element applies heat to the substrate, and,
wherein the second heating element is upstream of the substrate in relation to the fluid flow from the air inlet duct, and in thermal communication with the thin fluid film.
