Sample Specific Programs
These programs allow for parameters such as tube length, concentration, specific rotation, wavelength, sample measurement range, measurement scale and temperature correction to be pre-specified. The programs can be labeled with an alphanumeric name (e.g. Dextrose 2). The operator simply selects the sample program from the alphabetic list and the AUTOPOL’s is ready to make measurements. Sample specific programs can be set to read either Optical Rotation, specific rotation, concentration or user defined scales. A user defined scale is a linear equation based on the measured value and input parameters.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.White-light Source Permits Spectral Versatility

Print 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.![Autopol_IV-007 Polarimeter - Sample Printout](https://i0.wp.com/rudolphresearch.com/wp-content/uploads/2012/05/Autopol_IV-007.jpg?resize=700%2C1100&ssl=1)
USB, RS 232, and Printer Communication
The AUTOPOL® IV Essential Oils Polarimeter offers 3-USB ports, 1-USB 3.0, 2-RS 232 serial ports, and an Ethernet port for connecting to your network. The RS 232 port allows data to be sent to a computer when the print key is pressed, when the computer requests the data or at predefined time intervals. Measurements can be remotely controlled from a host computer and the printout format and parameters can be selected via menu entry. Utilizing a USB port, all plug-and-play Windows compatible printers may be added.Real-Time Clock
AUTOPOL®IV contains a real-time clock that tracks time and date. All measurements can be date and time stamped when printed out. The time is continually displayed in the upper right hand corner of the display.Essential Oils Polarimeter – 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.Essential Oils Polarimeter – Range Limits
Sample range limits can be specified in sample specific programs, (e.g. 24.8° Arc – 25.7° Arc). When a range is specified and the measurement falls outside this specification the display will read “out of range”. Two TTL level signals are available for out of range conditions. These signals are useful for process control or alarms.Essential Oils Polarimeter – Quality
No matter which Autopol automatic essential oils polarimeter you choose, Rudolph uses the same high quality optics. While other manufacturers use Polaroid Plastic Dichroic Sheet Polarizers, Rudolph does not. Instead, Rudolph uses the same high quality Glan Thompson Calcite Polarizers in all its models.![Autopol_IV-008 Polarimeter Optics](https://i0.wp.com/rudolphresearch.com/wp-content/uploads/2012/05/Autopol_IV-008.jpg?resize=700%2C363&ssl=1)
Essential Oils Polarimeter Calibration and Validation
Rudolph understands that today’s cGLP/cGMP laboratories must validate measurement and temperature. Therefore Rudolph offers 6 different NIST Traceable Quartz Calibration Standards that can be matched to your application. The Autopol® IV also comes with a Temperature Validation Cell so that your temperature measurement can be traced to NIST. See Technical Bulletin 913 for more information.![Autopol_IV-009 TempTrol - Polarimeter](https://i0.wp.com/rudolphresearch.com/wp-content/uploads/2012/05/Autopol_IV-009.jpg?resize=700%2C469&ssl=1)
