Description- The KERN OAB 20LED is an analogue polarimeter designed for routine laboratory use, offering ergonomic handling and straightforward operation.
- High-performance LED illumination (λ = 589 nm) provides a long service life and low maintenance compared with conventional sodium-vapour lamps.
- Brightness regulator allows precise adjustment of illumination for optimal reading conditions.
- Measurement based on optical rotation using the half‑shade principle ensures accurate and repeatable results.
- Flexible sample chamber accepts measuring tubes up to 220 mm in length.
- Delivery includes two measuring tubes (100 mm and 200 mm) with bubble trap, replacement lenses and sealing rings.
Main scope of applications- Laboratories (quality control, R&D)
- Pharmacies (incoming/outgoing checks of pharmaceutical products)
- Teaching and training centres (practical exercises, experiments)
- Chemical industry and analytical laboratories
- Food and beverage industry (sugar inversion kinetics, concentration determinations)
