Essential Oils Polarimeter|AUTOPOL®IV
for Chemical and Pharmaceutical Labs
The AUTOPOL IV Automatic Polarimeter is available in one, two and six wavelength versions. It 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 racemics and kinetics. Temperature control is done using the patented Rudolph TempTrol™ system. IQOQ documentation is included with the instrument.
The AUTOPOL IV Laboratory Polarimeter can readout directly in one of four measurement modes: Optical Rotation, Specific Rotation, Concentration or Specific Rotation Plus. Specific Rotation Plus allows a correction to be applied to a result for loss on drying. Each measurement mode can be activated via touchscreen selection. Sample tubes can be specified at any length (e.g. 50mm, l00mm, 200mm), or entered as a precise dimension (e.g., 199.98mm). Concentration is entered as a percentage.

Specifications
Overview
Why are high-quality
polarizing prisms important?
Rudolph manufactures its entry-level automatic polarimeter with the same high-quality optics as its more expensive instruments.
While other manufacturers in this price range use Polaroid Plastic Dichroic Sheet Polarizers, Rudolph does not. Instead, Rudolph uses the same high-quality Glan Thompson Calcite Polarizers used in its high-accuracy models.
Because prisms are two of the most critical optical components in the polarimeter. Polaroid prisms are made of a polymeric plastic where the molecules are stretched and oriented in a specific direction so as to linearly polarize light. These types of plastic sheet polarizers are very inexpensive ($50.00 USD) and are vulnerable to heat, warp over time, deteriorate from moisture, and also have greater light absorption than Calcite Polarizers.
In many cases, the plastic polarizers must be replaced in 3- 5 years. Glan Thompson Calcite Polarizers are comprised of a carbon crystalline structure similar to diamond and have excellent light transmission characteristics. The quality of these prisms is so good, Rudolph guarantees its prisms over the life of the sugar polarimeter.
Full Compliance
21CFR Part 11
The Autopol® V 21CFR Part 11 software module is easily enabled through the user-friendly touch screen. This module gives you full compliance with:
Multiple
Wavelengths
The AUTOPOL® IV Automatic Polarimeter comes in single, dual and six wavelength models. Wavelength selection is completely automatic and is accomplished via menu selection. There are no lamps or filters to manually remove or insert. The following wavelengths are available: 365nm, 405nm, 436nm, 546nm, 589nm and 633nm. Optional wavelengths include: 578nm, 880nm and various other wavelengths are available; contact the factory for more information.
Temperature
Display and Correction
The AUTOPOL® IV Automatic Essential Oils Polarimeter comes standard with a temperature probe which can be inserted into the Polarimeter cell as shown to the left. The temperature of either the sample compartment or the solution itself can be continuously displayed.
Print Format
Format
Numerous parameters, such as sample name, tube length, concentration, wavelength, time and date, temperature correction and statistics can be printed after each polarimeter measurement or after a group of measurements. This is accomplished by designating the required parameters, via menu entry, during the print format setup mode. A sample printout is shown below.

Statistics
AUTOPOL® IV calculates the mean, the standard deviation and records the minimum and maximum readings for up to 999 measurements Measured data for statistical calculation can be printed in either one of two ways: automatically, at predetermined time intervals or manually, by pressing the print key. Statistics for a batch of samples can be accomplished by pressing the page feed key. Statistics on time varying optically active samples can be compiled by measuring a sample at a predetermined rate and for a predetermined number of measurements.
