Polarimeters

Introduction to Polarimeters

A polarimeter is an optical instrument used to measure the optical rotation angle of optically active substances in solution, thereby determining sample concentration or purity. The equipment is widely used in pharmaceutical quality control, food analysis, and the sugar industry.

When choosing a polarimeter, users should clearly define their analytical purpose to select the appropriate model and configuration package. Depending on actual requirements, the device can support conversion to the International Sugar Scale (°Z) for the sugar industry or comply with GMP and GLP standards for pharmaceutical applications. Hoa Viet currently supplies automatic polarimeters from Atago (Japan), such as the AP-300 and SAC-i, along with various specialized configuration packages for each research and testing field.

Which polarimeter brands does Hoa Viet distribute?

Hoa Viet currently distributes automatic polarimeter lines from Atago (Japan), typically the AP-300 and SAC-i series.

What requirements do the configuration packages of the Atago AP-300 polarimeter serve?

This series offers specialized packages including Package Type A and Type B for measuring optical rotation and the International Sugar Scale (°Z) in the sugar industry, Package Type C complying with GMP and GLP standards, and Package Type D dedicated to the pharmaceutical industry.

How does an automatic polarimeter operate in the laboratory?

The device operates by placing the sample-filled observation tube into the sample chamber and pressing the start key for automatic measurement of the optical rotation angle. Analysis results are displayed directly on the digital screen for observation and recording.

What should be noted when storing polarimeter sample tubes?

The observation tube must be cleaned and its optical transmission surfaces dried immediately after measurement to prevent chemical residue build-up. When not in use, store the tube in its dedicated case and keep the instrument chamber clean and dry.
