UniPol V – Digital Polarimeter

UniPol V – Digital Polarimeter

The fully automatic digital polarimeter Unipol V is especially designed for chemical applications. It can also be used for purity analysis of food and beverage as well as cosmetics. The resolution of UniPol V conforms to the European and American Pharmacopeia. GLP/GMP conform data can be directly printed or transferred to your PC. In conjunction with the SCHMIDT + HAENSCH Software AQUISYS 3, all requirements of 21 CFR Part 11 conformity are fulfilled.


  • Basic circle polarimeter
  • Quasi-continuous measurement
  • Reliable high precision
  • 21 CFR Part 11 ready
  • Compliance with international standards

Easy to use

The measuring range of ± 360° can be divided in user-selected segments which can be easily selected by the menu. The user- friendly menu structure of the instrument is easily operated with the splash-proof alphanumerical keyboard. Software design close to practice enables the user to input sample ID-numbers, calculate statistical evaluation, and configure user defined printout of the measuring results. The measuring values are shown on the large 7″ Touchscreen display.


The fully automatic digital polarimeter UniPol V was particularly designed for chemical applications, but it also has numerous applications in purity analysis in the food and beverage and cosmetics industries. Optically active substances can be easily measured and raw material quality identified. Compliance with the International Pharmacopoeia is guaranteed.

Product in detail

The standard model is equipped with a 589 nm light source. Other wavelengths are available upon request. Various chemically resistant polarimeter tubes are available for different applications. With the use of micro tubes, smallest sample volumes are sufficient. The polarimeter UniPol V is equipped with plug-in connector for the temperature sensor of the SCHMIDT + HAENSCH polarimetric tubes. If polarimeter tubes or quartz control plates with integrated temperature sensor are used the current sample or quartz temperature is indicated on the display.

Maintenance and calibration can be done with quartz control plates manufactured in our company in the heart of Berlin.
