ADP600 series multi-wavelength polarimeters

Nuoroda į produkto svetainę

Temperature controlled polarimeters

Available as single, dual and multiple wavelength derivatives not only covering the visible spectrum, the new ADP600 Series of Peltier temperature controlled polarimeters are capable of measuring optical rotation to four decimal places in the highly sensitive ultra-violet region. This capability makes the instrument particularly suited for use by scientists wishing to measure chiral compounds and other optically active substances in the chemical, pharmaceutical and food sectors as well as for use in academic research.

Sample tubes & Peltier control

Peltier technology is intelligently applied to the sample chamber of the new polarimeters so that measurement can be accurately made without the need of an external device such as a waterbath to control sample temperature. The ADP600 Series Polarimeters have two preset operating temperatures being 20 and 25 °C in accordance with European and United States Pharmacopoeia respectively and other user temperatures between 20 and 30 °C may be configured via the instrument user interface.

Touch-screen display & methods

Integral to operational simplicity is the full color, high definition, touch-screen graphical user interface. A menu structure featuring a METHODS system makes for one-touch calibration and instrument configuration.

A “Mean Method” is also available, allowing a number of readings to be taken from a production batch with the mean being calculated and recorded once the experiment has been completed. The Mean Method is ideal for pharmaceutical applications where compliance with pharmacopoeia is required.

Additionally the ADP600 Series Polarimeters feature a secure “print to PDF” function that may be configured to operate in secure environments in accordance with FDA regulation 21 CFR Part 11 and importantly, the ADP600 Series polarimeters meet all of the requirements, including wavelength directives of British, United States, European and Japanese Pharmacopoeia.
