KERN OAB-20LED

The KERN OAB-20LED is a manual polarimeter designed for simple and precise measurement of optical rotation. It is used in laboratories, schools, and production facilities to test substances like sugars, essential oils, and pharmaceuticals. The device combines an easy manual design with accurate optical technology, making it reliable for daily use.

This polarimeter works with the half-shade principle to measure the rotation of polarized light passing through a sample. It provides accurate results over a range of -180° to +180°. The built in LED light source replaces traditional sodium-vapor lamps and has a much longer service life. The LED illumination is stable, energy efficient, and adjustable in brightness for better visibility and comfort during measurement.

The flexible sample chamber accepts measuring tubes up to 220 mm in length. This allows the user to test both small and large liquid volumes. The package includes two glass measuring tubes (100 mm and 200 mm), each with a bubble trap for easy filling, plus spare lenses and sealing rings.

The OAB 20LED is compact, durable, and designed for low maintenance. It is perfect for labs in the pharmaceutical, chemical, beverage, and food industries, as well as for teaching and research institutions. Typical uses include checking sugar content, studying chemical reactions, and verifying product purity.

Its clear optical system and simple mechanical control make it easy to handle, even for beginners. The built in power supply ensures stable illumination during long measuring sessions.
