AUTOMATIC POLARIMETER

Model: AA65

Manufacturer: OA INDEX – ANH 

Features & Benefits:

  • The new AA-65 is a versatile polarimeter suitable for measuring the optical rotations of many different types of samples from sugars to pharmaceutical products. The polarimeter is extremely easy to use and has a touchscreen digital display presenting on-screen data in full colour.

The AA65 is available in 3 versions:

  • Single scale angular giving optical rotation in angular degrees
  • Sugar Industry model giving rotation in sugar degrees (ºZ) calibrated in International Sugar Scale (I.S.S.) in accordance with current I.C.U.M.S.A. recommendations. This model also offers temperature corrected sugar scale and includes 26g, 13g and 6.5g scales. Results can also be displayed in angular degrees.
  • Analytical Model offering angular degrees and specific rotation and concentration scales, along with the option to enter a scaling factor to simulate any scale required by the user
  • The working wavelength of 589.44nm is determined by means of a factory fitted optical interference filter. The model type – angular scale (A65), sugar industry Z65 or analytical model (MA65) – is printed on the instrument label inside the sample compartment.
  • The sample compartment has a removable temperature sensor. Optionally, you can purchase a ‘dip-in’ temperature sensor for use with A1 and G7 single sample tubes, or, for flow type tubes, an end cap with temperature sensor fitted. These optional temperature sensors are available to provide much faster and more accurate measurement of the actual sample temperature.
