The POLAX‑2L polarimeter with temperature controller is a semi‑automatic high‑precision instrument for measuring optical rotation, specific rotation, concentration, and sugar content in various solutions. Its integrated temperature control system (5…40 °C) ensures maximum measurement accuracy and stability by eliminating the effect of temperature fluctuations. The POLAX‑2L is widely used in the food industry (quality control of sugar, beverages, and syrups), pharmaceuticals (determination of substance purity), and chemical laboratories. With easy operation, a reliable optical system, and a durable design, it is the optimal choice for professional laboratories requiring reproducibility and compliance with international standards.
