Optical rotation is a phenomenon wherein light vibrating in one fixed direction polarized light passes through a liquid sample and rotates. The point at which it tilts is called the "angle of rotation. The angle of rotation changes depending on the concentration of the liquid sample, the length of the observation tube, the temperature, and the measurement wavelength. Specific rotation is a characteristic value related to optical activity, standardized for each and every substance. There are set values determined for every substance, printed in literature such as chemistry handbooks. The density of a solution made when dissolving an optically active substance in optically inactive water and alcohol is called "concentration.

Polarimeter models from Rudolph Research for chemical, sugar, pharmaceutical, cosmetics, essential oils, education, and university laboratories. Trouble viewing this video? Click Here. The built in Ethernet port allows saving data directly to your network server and printing to a network printer.
It is the system of choice for research universities, pharmaceutical and fine chemical research departments. This instrument is also excellent for studying recimics and kinetics. IQOQ documentation is included with the instrument. Please review the USP monograph for the material Ofloxacin. Biots Law:. Below is how its relative accuracy affects a hypothetical Ofloxacin sample:. The Autopol IV has an accuracy of 0. This accuracy is applicable for food, university education, many chemical, flavor and fragrance applications, as well as pharmaceutical inspection in some countries.
This accuracy is fine for food and educational applications where budget is critical but state of the art quality is still important. Rudolph has demonstrated a commitment to its customers by keeping installed instruments operational, not only for 20 years, but in some cases for over 40 years.
This long-term commitment to keeping our instruments running makes the cost of ownership, over the life of a Rudolph Instrument, one of the lowest in the laboratory market segment.

Polarimeter Model Selection Guide
A polarimeter  is a scientific instrument used to measure the angle of rotation caused by passing polarized light through an optically active substance. Some chemical substances are optically active, and polarized uni-directional light will rotate either to the left counter-clockwise or right clockwise when passed through these substances. The amount by which the light is rotated is known as the angle of rotation. The angle of rotation is basically known as observed angle. A nicol prism or a polaroid filter can be used to polarize the light. The ratio, the purity, and the concentration of two enantiomers can be measured via polarimetry. Enantiomers are characterized by their property to rotate the plane of linear polarized light.
