Centrifugal microfluidic devices offer a robust method for low-volume fluid handling by combining low-cost instrumentation with highly integrated automation. Crucial to the efficacy of Lab-on-a-Disc (LoaD) device operation is selection valving technology, design on-disc fluidic structures, and accurate control disc spin-speeds (centrifugal force) during operation. The refinement structures often guided inspecting using high-speed camera systems. This approach involves synchronising image acquisition rotation visualise liquid flow through series images presented in video format. Depending on decisions taken, such systems can cost from €4,000 upwards. paper outlines development centrifugal test-stand an imaging system generic wireless record videos directly smartphone device. be fabricated only 3D printers CNC milling machine widely available materials approximately €350.
