AUTOPOL III Polarimeter

The AUTOPOL III Polarimeter is Rudolph’s entry level Pharmaceutical and Research grade Automatic Digital Polarimeter. The Autopol III offers Dual Wavelengths and accuracy similar to Rudolph’s more advanced models, but with a simplified interface. Just place your cell in the sample chamber, press the Start Key and get 5 results in less than 25 seconds. It’s that easy.

Autopol III Polarimeter Standard Features:

  • Accuracy 0.002°C,  0.2% above 1°
  • 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 7 for direct connection to the network server and flexible USB Printing.

Optional Features:

  • TempTrol™ Automatic Electronic Heating & Cooling 15° – 40°C ±0.2°
  • 365nm, 405nm, 436nm, 578nm, and 633nm wavelengths. (A total of 2-4 wavelengths may be ordered initially or as needed)
  • AP Accuracy Option: 0.002° up to 10° Arc
  • AP Resolution Option: 0.01, 0.001°, 0.0001° Arc Selectable.


A cGLP/GMP compliant printout, which includes the temperature of the sample is generated by pressing the Print/Send Key after the measurement is finished.

Autopol III Polarimeter Accessory Packages

The Autopol III Polarimeter comes standard with one of the three different Polarimeter Accessory Packages shown below. Each Package includes a NIST Traceable Calibration Standard and Certificate, two Tungsten Halogen Lightsource lamps and an alignment target, but different cell configurations. You select the package that is right for your lab.

Accessory Package A includes one 100mm, 6ml glass center fill cell and one 100mm, 6ml glass center fill stainless steel jacketed cell. This is our most popular package, as cell windows can be removed and cleaned to avoid sample residue build up. All cells in this package are compatible with acids.

Accessory Package B includes one 50mm glass jacketed fixed end cell and one 100mm glass center fill cell with removable windows. Fused end cells avoid improper assembly by untrained users, but are very fragile and difficult to clean. All cells in this package are compatible with acids.

Accessory Package C is designed for small volume and durability and is very popular with universities. Each cell has a lifetime warranty against breakage, is easily filled and cell windows can be removed, cleaned and replaced if necessary. Cells are available in 50mm, 100mm and 200mm length versions. Cell volumes range from 0.5ml to 15ml.
