Since 1996, the ADP range of polarimeters has become one of the world's most popular general-purpose automatic polarimeters. Building on the experience gained over the past decade of polarimeter design, Bellingham + Stanley continue the tradition by introducing the ADP410, incorporating up to date technology and delivering a high quality instrument at an affordable price. The ADP410 provides all the measurement performance of its predecessor, the ADP220, but with less software features.
The instrument is housed in a rugged chemical resistant case making it suitable for use in factory environments as well as in the laboratory. Different types of tubes are available depending on the application, including those manufactured of glass in a variety of lengths and style, as well as water-jacketed tubes for temperature controlled work and flow tubes for autosampler and funnel feed applications. The latter two types may require the use of specially suited lids.
Operation is very simple by way of four graphically identified push buttons including scale and compensation selection, zero calibration and the displaying of optical density and temperature. Results are shown on a bright LED display and may be printed via an RS232 interface.
Temperature compensation can be achieved from a single sensor, which can measure either the temperature within the sample chamber or, when placed in the centre-filling arm of the measurement tube, the temperature of the actual sample.
The sample reading value and optical density are alternately displayed by repeatedly pressing the READ key. The instrument can be checked and calibrated using quartz control plates by accessing the span facility in the setup menu. If a sample is too dark, the instrument will display an error message.
An LED and narrow band interference filter provides illumination of the sample and requires no maintenance.
