Rudolph - Polarimeters - Autopol Series

Polarimeter models from Rudolph Research for chemical, sugar, pharmaceutical, cosmetics, essential oils, education, and university laboratories.

Available models

The AUTOPOL I Automatic Polarimeter is Rudolph’s single wave length model with an accuracy of ±0.02 Degrees Optical Rotation. This accuracy is fine for food and educational applications where budget is critical but state of the art quality is still important. Suitable for Non-USP or high concentration Pharmaceutical raw materials measurements.

Key features

  • 0.01° Arc Accuracy.
  • 589nm fixed wavelength.
  • Built in thermoprobe for temperature measurement.
  • Windows Embedded OS for direct connection to the network server and flexible USB Printing.

The AUTOPOL II Automatic Polarimeter is a general-purpose polarimeter with ±0.01 Degrees Optical Rotation accuracy. This accuracy is applicable for food, university education, many chemical, flavor and fragrance applications, as well as pharmaceutical inspection in some countries.

Key features

  • 0.01° Arc Accuracy.
  • 589nm and 546nm wavelengths. (A total of 2-4 wavelengths may be ordered initially or as needed)
  • Built in thermoprobe for temperature measurement.
  • Windows Embedded for direct connection to the network server and flexible USB Printing.

The AUTOPOL III Automatic Polarimeter is Rudolph’s two wavelegnth  pharmaceutical and research grade instrument  which has a ±0.002 Degrees Optical Rotation accuracy for rotations up to 1° Arc. This polarimeter comes standard with two wavelengths: 589nm and 546nm and will pass an FDA inspection with the appropriate water bath to control temperature or with optional Temptrol™ Electronic Heating and Cooling. IQOQ documentation is included with the instrument.

Key features

  • Accuracy 0.002° Arc up to 1°,  0.2% above 1°, 0.01° Z(ISS)
  • 589nm and 546nm wavelengths. (A total of 2-4 wavelengths may be ordered initially or as needed)
  • Complete Accessory Package with IQOQPQ documentation, 2 user selectable sample cells, and 1 NIST traceable calibration standard with NIST certificate.
  • Built in thermoprobe for temperature measurement.
  • Temperature Probe is covered with a micron thick glass coating to stand up to high molar Hydrochloric Acids used by some pharmaceutical labs.
  • Windows Embedded for direct connection to the network server and flexible USB Printing.

The AUTOPOL IV Automatic Polarimeter is available in one, two and six wavelength versions and has a more expensive optical system than the Autopol III. It is the system of choice for research universities, pharmaceutical and fine chemical research departments. This instrument is also excellent for studying recimics and kinetics. Temperature control is accomplished using the patented Rudolph TempTrol™ system. IQOQ documentation is included with the instrument.

Key features

  • Measures Optical Rotation, Specific Rotation, Concentration, and User Defined Scales
  • Temptrol™ Electronic Heating and Cooling
  • 1, 2 and 6 wavelength models
  • Temperature Correction
  • Real-time clock
  • Print-out format control
  • Designed for use in Pharmaceutical, University, Essential Oil, and related industries.

The AUTOPOL V Automatic Polarimeter is designed for today’s FDA regulated analytical laboratories. Whether you are a Pharmaceutical, Nutraceutical or University Lab, the AUTOPOL V has the standard measurement and compliance features you must have.

Key features

  • 21CFR Part 11 Compliant
  • Temptrol™ Electronic Heating and Cooling
  • Six standard wavelengths
  • Touch panel user interface
  • Designed for use in FDA regulated Pharmaceutical, Nutraceutical and cGMP/GLP laboratories

The AUTOPOL V PLUS Automatic Polarimeter is Rudolph’s top of the line six wavelength instrument specifically designed with the input of the world’s largest pharmaceutical companies. This unit comes standard with 21CFR11 software and Rudolph’s Patented TempTrol™ System, which electronically heats and cools the sample to a specified temperature without the use of water circulation.This unit includes all wavelengths necessary to measure 99% of all monographs found in the USP, EP, JP and BP. IQOQ (Installation Quality Operation Quality) documentation is included with the instrument.

Key features

  • 6m HCl acid resistance: Silco Steel coating on the chamber temperature transfer surface and a Hastelloy measurement cell with NIST certificate certifying optical path length.
  • Comes with a NIST traceable quartz plate with three rotations: +0.998° Arc, +10.998° Arc, -10.000° Arc. Each rotation has a NIST certificate.
  • Intuitive Windows® based navigation architecture
