Polarimetry

analysis of food samples

The ADP220 is one of the most commonly used automatic polarimeters, in the world, thanks to its flexibility, making it suitable for use in a number of application fields.

The improvements from an optical point of view have enabled the strengthening of the already excellent base in the previous series, increasing reproducibility and analytical sensitivity.

B+ S, with 80 years of experience in the industry at its back, has produced a high-quality instrument using the latest technology, while maintaining a very low cost in relation to its specifications.

The models in the ADP220 series are fully automatic polarimeters, capable of measuring the angle of rotation of optically active samples in a simple, automatic, rapid and reproducible fashion.

The operation and interface are very simple; you can run the analysis and printing of data at the touch of a button; other parameters can be configured or directly at instrumental level or through a dedicated management, control and processing software.

The main configurable parameters include:

"the reading scale

"the zero setting

»the automatic temperature correction and

"automatic correction based on the production material of the measuring tube

The results can be displayed on the instrument display, or printed directly and viewed via personal computers and related software

Polarimetry accessories

The polarimeteric tubes can reach a maximum length of 220mm with or without temperature control of both the polarimeter tube as well as the sample sector.

A temperature probe inside the samples compartment to control the temperature of the housing, while a second probe directly measures the temperature of the sample.

The thermostat water pipes can be used to obtain a more precise temperature control.

In certain applications, the ADP220 can be used with a full flow tube of the funnel, thus allowing the new sample to remove the one just measured and thus eliminating the need to regularly clean the tube between one sample and the other.

The optical rotation measurements require that the sample is placed in a tube from the optical path defined according to the application of analytical interest.
