• AUTOPOL VI Suppliers


The AUTOPOL VI Automatic Polarimeter was developed for the most demanding analytical laboratories. If your laboratory requires the highest accuracy and must meet the most stringent compliance standards, the Autopol VI has the measurement, temperature control, communications, and data tracking capabilities your application requires.

Versatile Communication Capability

The AUTOPOL VI polarimeter’s standard communication package includes:

  • Ethernet port for Network Cable Connection
  • 3 USB ports
  • 2 RS 232 ports

Allowing the capability to:

  • Connect directly to Rudolph’s service department for remote testing and diagnostics via Internet connection.
  • Connect to any Windows® based printer via USB or direct to the server via Windows® Print Library
  • Save measurement data direct to your Network/Server

Automatic, Electronic Polarimeter Temperature Control System using TempTrol

The USP <781> require optical rotation measurements at 25°C ± .5°C (unless another temperature is specified). The European Pharmacopoeia requires optical rotation measurements made at 25°C ± 5°C (unless another temperature is specified).

Whatever your temperature control needs are, the AUTOPOL VI’s exclusive TempTrol™ System (Patent No. 2778542) makes your measurement in seconds without a waterbath or any type of water circulation.

The TempTrol™ System allows push-button temperature control of your 100mm cell, 200mm cell, or Quartz Plate. Set the temperature, push “measure” and walk away. The AUTOPOL VI will heat or cool to a predefined temperature and then provide you with the result all in one easy step.

cGMP/GLP Printing

Measurement reports can be saved as an Excel or PDF file and edited quickly and easily. You can import logos and print your company’s customized “C of A” directly directly from the Autopol VI Polarimeter.

Validation and Calibration

Rudolph Research Analytical knows that you must be able to validate your polarimeter’s operating performance regularly. Therefore, the AUTOPOL VI comes standard with the accessories, validation tool and automatic calibration functions necessary to ensure that the temperature control, temperature measurement and optical measurement processes are working accurately and reproducibly. All functions are assessed simply and conveniently through the AUTOPOL VI liquid sealed touch screen.

Unmatched Accuracy

For Racemic Solutions and very low concentration samples, the AUTOPOL VI provides unmatched 4th decimal Optical Rotation accuracy of ±0.0003°Arc over ±1°Arc. Instrument performance for readings between -1 and 1° Arc is: Resolution ±0.0001, Reproducibility ± 0.0002, and Accuracy ±0.0003.

Intuitive Windows® 7 Embedded Interface

  • 8 gigabytes of internal memory allow almost unlimited capacity for saving measurement data. The AUTOPOL VI is network ready and data may also be saved directly to your server or to any directory desired.
  • Internet access is possible directly from the AUTOPOL VI’s touch screen. This feature allows real time contact with Rudolph Research Analytical’s Service and Technical Support Team who can access your instrument remotely to assist in Window navigation, method setup and troubleshooting.
  • Windows based navigation architecture is so intuitive that most operators will never read the manual. But should you wish to reference the manual, it is stored right on the AUTOPOL VI’s internal memory.
  • Three USB ports allow quick and easy connection to a mouse, keyboard, printer, bar code scanner, or memory stick. One USB port is located on the front of the unit and two USB ports are located on the back of the unit.

Flexible Method Management

Install your own measurement methods for immediate selection of the correct method to match your most common tests. Setting up your own custom methods is as simple as filling out a few screens like the one shown to the right.

Full 21CFR Part 11 Instrument Level Compliance

The AUTOPOL VI’s 21CFR Part 11 software module is easily enabled through the user friendly touch screen. This module gives you full compliance with:

  • Electronic signature
  • Access levels
  • Internal write protected storage
  • Unique passwords
  • Write protected documents sent directly to server
  • Audit trail

Acid Resistance

The AUTOPOL VI polarimeter comes standard with Rudolph’s Hastelloy upgrade option. This option includes a Hastelloy cell and Silco Steel™ cell chamber for increased resistance to acids like 6 Molar HCl.

Rudolph Research Analytical — still protecting your investment after 30 years

Today our Service Technicians have access to state of the art diagnostic tools and have a depth of knowledge that often lets them solve problems right over the phone. Our customers really appreciate the same day phone call by a real technical service person who wants to solve their problem. Our customers know that they can expect this support for many years to come as Rudolph is still repairing instruments which were built in the 70’s.
