KERRO Manual Disc Polarimeter
KERRO Manual Disc Polarimeter (Model: WXG-4)
The KERRO WXG-4 is a reliable and user-friendly manual polarimeter designed for accurately measuring the optical rotation of optically active substances. It is an essential instrument for educational purposes and for straightforward quality control applications in the food, sugar, chemical, and pharmaceutical industries. This instrument operates on the principle of visual null-point detection. The user looks through the eyepiece and manually rotates the analyzer disc until the split-field of view appears uniformly illuminated. The optical rotation value is then read directly from the clear, easy-to-read scale with a vernier, providing a measurement range of ±180°. A key modern feature of the WXG-4 is its long-lasting and stable LED light source. Unlike traditional sodium lamps, the LED provides consistent monochromatic light instantly, requires no warm-up time, generates minimal heat, and has a significantly longer lifespan, reducing maintenance and operational costs. The robust metal construction ensures durability and stability for daily laboratory use. Key Features: KERRO Manual Disc Polarimeter
