A Filipino physics student has built a low-cost polarimeter using LEGO bricks and other simple components. This innovative device can measure the purity of substances like Vitamin C, offering potential applications in education and quality control.
USING simple circuitry, polarizing film, and LEGO toy bricks, an undergraduate physics student from the Ateneo de Manila University recently built an improvised polarimeter that can optically assess the purity of Vitamin C and other chiral substances. The device has potential applications in classrooms as a learning tool, and may pave the way for more cost-effective means to monitor the quality of some consumer products.
The Filipino researchers modified the original design and refined the detection process to obtain reliable and accurate measurements that are crucial for ascorbic acid, whose specific rotation is relatively low..By using easily-purchased items like LEGO bricks, polarizing film, and cheap off-the-shelf electrical components, Felicidario was able to bring the cost of the polarimeter down to just over $150.
