Polartronic N & M series Full Circle Polarimeters

The N and M series are the latest versions of a long and celebrated line of Polartronics from Schmidt and Haensch. Famous for their speed, accuracy and reliablity, the new Polartronics incorporate the latest in digital electronics and data processing. These instruments are industrial strength designed for determine the optical activity of a solution by means of a rotating analyzer linked to an optical encoder. They include the Schmidt and Haensch patented direct linking of the polarizing analyzer to the optical position encoder, ensuring constant resolution throughout the range, high accuracy and touch screen option repeatability. Also these polarimeters are up to 5 times faster than competitive instruments. The Polartronics are automatic full circle polarimeters designed for continuous measurement operation. It is never necessary to return to a start or zero position in order to initiate a new measurement.  The N&M series work with standard and specialized Polarimeter tubes for continuous flow, temperature measurement, micro-tubes for precious samples. There are several models to choose from suitable for routine lab work, and saccharimetry. These instruments are ideal for production quality control and research because of their outstanding specification and robust construction

The software implements amongst other features the input of sample identification numbers, statistic evaluations of multiple measurements and user definable printouts individually configurable for each of the 4 available methods. The N and M series are available as single or double wavelenth (including IR) configurations. A touch screen option offers an enhanced graphical display and data management features.

All models conform with the regulations of the European and American Pharmacopoeias as well as to the GLP/GMP standards.

Temperature measurement of samples is very important to ensure precise and stable measuring results. The Polartronic-series displays the actual sample temperature and compensates automatically the temperature deviation compared to the standard temperature when polarimetric tubes or quartz control plates with a temperature sensor are used. The scale value (e.g. °Z, °S …) is displayed corrected to the standard temperature.

The polarimeters are equipped with plug in connectors for the temperature sensor of the temperature contolled polarimeter tubepolarimetric tubes. If polarimeter tubes or quartz control plates with integrated temperature sensor are used the current sample or quartz temperature is indicated at the display.

Flow through sample system continuous or pour with integrated temperature sensor.-->


The measuring compartment can accept a wide range of standard and specialized polarimeter tube including micro tubes, pour-through and continous flow tubes, temperature measurement and temperature controlled tubes. Standard tubes come in lengths of 50mm,100mm and 200mm with filler cups, bubble traps or plain straight tubes.
