Microcavity plasma devices show promise for controlled plasma chemistry. However, these devices are typically made through processes that are difficult to scale up. We present the design and characterization of a microchannel system suitable for the study of microplasmas. The channel was created with a micro-mill CNC machine that allows for quick device manufacturing. The channel is characterized using scanning electron microscopy and profilometry. Finally, we use recently published models of flow in a microchannel with bends to elucidate pressure conditions throughout the channel. Future work will encompass characterization of plasma conditions.
