ADP 430 & ADP 450, ADP 400 Polarimeters - Single Wavelength Polarimeters (with or without Peltier)

The ADP400 Series of general-purpose, single wavelength polarimeters are suitable for sugar, food, chemical and pharmaceutical industries where measurement is required to 3-decimal place resolution (°A) over a length between 10 and 200mm. The ADP400 polarimeters are available with or without XPC – Xylem’s patented internal Peltier temperature control system.

ADP400 series polarimeters feature a ‘no maintenance’ LED light source and interference filter with photodiode detector technology that provides sample readings up to 3.0 OD at the commonly used sodium (589nm) wavelength. Conveniently, ADP400 Series instruments use standard polarimeter tubes or for scarce samples, low volume luer taper tubes.

ADP400 Series polarimeters now feature a full colour, 4” (10 cm) high-definition display. Measurement may be expressed as angular degrees (°A), sugar (ISS) or user programmable scales, with standard Methods facilitating display of invert sugar, inversion (A-B) or, when applying other factors such as tube length and concentration, Specific Rotation (or concentration when entering specific rotation).

Methods and measuring of ADP400 Series

The ADP400 Series offers both continuous and ‘single shot’ reading modes, the latter being ideal for pharmaceutical applications where a discrete value is required without interpretation by an operator.

The PHR-MEAN Method, integral to both ADP400 Series polarimeters, allows a number of different readings to be taken from a batch of samples and the statistical report, showing the average, high and low results together with standard deviation can then be printed or stored to file.

The expanded memory ensures that over 8000 measurements and recorded logs of instrument configuration can be saved and viewed or output to LIMS.

Calibration and configuration can be password protected, accessible by keypad entry or, for convenience, using a fully configurable RFID tag. This, together with the audit trail, facilitates operation in environments conforming to FDA regulation 21 CFR Part 11 or GLP. ADP400 Series polarimeters are also ideal for use within laboratories where compliance with Pharmacopoeia is required.

The ADP400 Series polarimeters incorporate a number of industry standard interfaces making it easy to connect to peripheral devices including barcode readers, printers and USB memory sticks for external storage. With the addition of a USB memory stick operators can output results to a secure PDF using the “Print to Secure PDF.” The USB port can also be used to accept RS232 via an available adaptor.

Two Instruments of ADP400 Series

There are two instruments in the ADP400 Series.

1. ADP430 Polarimeter

The ADP430 is a fully featured instrument designed for use in applications where internal temperature control is not required or where the use of automatic temperature compensation or a water bath is preferred, such as within the food industry.

2. ADP450 Polarimeter

The ADP450 polarimeter with patented XPC technology features interchangeable contact Peltier plates facilitating measurement at a stable temperature using Peltier control.
XPC technology conveniently stabilises the temperature of the sample being measured. With SMART temperature stability enabled, the ADP450 will only give a result when the instrument has displayed a stable temperature over a predetermined timeframe, making for reliable results in compliance with good laboratory practice.
