The AUTOPOL V Plus Automatic Polarimeter has the validation tools and features to satisfy today’s global pharmaceutical companies, including: instrument level 21CFR Part 11 compliance, NIST traceable calibration standards and a global list of installations. Rudolph Research has thousands of satisfied customers who praise the Autopol® V Plus’s quality, accuracy and reproducibility.

The AUTOPOL IV is a microprocessor based automatic polarimeter that is available in one, two and six wavelength versions. 

All J457’s come with Smart MeasureTM Technology that automatically detects when the prism is improperly cleaned, insufficient sample is loaded, or if the instrument is improperly calibrated. 

The DDM 2910 Density Meter, with high precision Peltier temperature control of sample, easy to use touchscreen User Interface, has the features to meet your needs in density measurements.

The DDM 2911 Density Meter, with high precision Peltier temperature control of sample, easy to use touchscreen User Interface, has the features to meet your needs in density measurements.

The J57HA was designed to meet the unique needs of food quality testing where the refractometer is viewed as a QC tool rather than a laboratory instrument. A single flat measurement surface, electronic temperature control and one button measurement capability make it perfect for heavy use applications.

The J47 was designed to meet the unique needs of a food and beverage testing where the samples are mostly a mixture of sugar and water and there fractometer is viewed more as a tool than a laboratory instrument. The J47’s single flat measurement surface, temperature correction and one button measurement capability make it perfect for heavy use applications. 

Designed as a research quality instrument the Rudolph J357 Digital, Bench-top Refractometer has the highest performance of any refractometer in the Rudolph range. This instrument offers the same extra wide RI measurement range as our chemical industry refractometer model combined with the high accuracy of our food industry refractometer models. It also offers the most powerful automatic temperature control (heating and cooling) and is able to make RI and BRIX measurements at up to 120 °C.

The AUTOPOL III Automatic Polarimeter is Rudolph's entry level Dual Wavelength Pharmaceutical and Research grade polarimeter offering accuracy similar to Rudolph's more advanced models, but with a simplified interface. Just place your cell in the sample chamber, press the large red MeasureKey and get 5 results in less than 25 seconds. It's that easy.
