Polarimeters, Refractometers

Introduction to Polarimeters, Refractometers

Polarimeters and refractometers are optical instruments used to determine the optical rotation angle of optically active substances and measure the refractive index to determine solution concentrations in laboratories. These instruments serve testing and analysis across diverse industries including pharmaceuticals, agriculture, food, and sugar processing.

When purchasing, users need to clearly define the instrument type, including MASTER series manual handheld refractometers, PAL series digital handheld refractometers, or AP-300 and SAC-i series automatic benchtop polarimeters. Depending on technical needs, customers can choose configuration packages compliant with GMP, GLP, International Sugar Scale (°Z), or specialized scales for salt and agricultural products from Japan's Atago brand. Please contact Hoa Viet for advice and a quote on suitable equipment.

How do polarimeters and refractometers differ in measurement principle?

Refractometers measure the refraction of light passing through a sample to determine refractive index or solute concentration. Meanwhile, polarimeters measure the degree of rotation of the plane of polarized light when passing through solutions containing optically active substances.

Which manufacturer's polarimeters and refractometers does Hoa Viet supply?

Hoa Viet currently supplies polarimeters and refractometers from Atago (Japan), including benchtop automatic polarimeters as well as handheld optical and digital refractometers.

Should I choose the MASTER series optical refractometers or the PAL series digital pocket refractometers?

The MASTER series consists of optical refractometers with direct reading through an eyepiece, suitable for basic on-site analysis without requiring batteries. The PAL series consists of compact digital pocket refractometers, displaying instant results on a digital screen to ensure fast operation and eliminate user reading errors.

What specialized configuration packages are available for the Atago AP-300 polarimeter?

The instrument offers various application-specific configuration packages, including Package Type A and Type B for the sugar industry with International Sugar Scale (°Z) measurement, Package Type C compliant with GMP and GLP standards, and Package Type D dedicated to the pharmaceutical industry.
