Testing a Sample with the POTA Device (IMAGE)
Caption
This compact, custom-cut device (80x80x40 mm) is designed to analyze liquid samples. It uses a standard 2 mL glass vial as a testing container. While these cheap, easy-to-use vials usually cause light distortion and measurement noise, our device solves this problem using a built-in "spatial filter" that absorbs distracting stray light. Thanks to this smart design, it only needs a tiny drop of liquid—just 500 μL—to get an accurate reading.
