We are offering sts-222a automatic polarimeter is the basic scientific instrument used to measure angle of rotation, specific optical rotation of optically active substance. automatic measurement: sts-222a built-in auto-controlling system. Power on the polarimeter, the system will search for zero point automatically. You need only put the sample tube in measuring field chamber, the polarimeter will display the angle of rotation. auto-judge substance form levorotatory or dextrorotatory: the polarimeter can auto-judge compoundor form levorotatory or dextrorotatory. If there is negative measures value, that means is levorotatory substance, if appearing positive measures value, it means is dextrorotatory substance. what's included: 100200mm tube, sodium lamp. reproducibility: in experiment, you need test a sample solution three times or more to ensure the accuracy of the measured value, you can press [ + ] or [ - ] key and the polarimeter will test again. The polarimeter not only can test the angle of rotation of substance and but can calculate its purity, concentration and percentage. technical specification: measuring range : -45°~+45° accuracy : ±0.02° reproducibility : ±0.01° resolution: 0.005° light source : sodium lamp optical wavelengths : 589.44nm stable time : 5 minutes tube length : up to 200mm power requirements : 220vac50hz weight : 25kg

Polarimeter is an instrument used for determining optical rotation of substances. It is also used for measuring specific rotation, concentration & international sugar scale of optically active substances. Polarimeter is ideal for pharmaceutical, food and beverages, sugar, cosmetics, oil refinery, chemical industries & also scientific research studies. CONTECH Digital Polarimeter is a fully automatic instrument and eliminates the need for manual adjustments thus offering a high degree of measurement precision. The polarized light after passing through the sample falling on the analyzer deviates from the optical zero position to the extent of optical rotation of the sample and the photomultiplier detector will produce an electrical signal with the frequency corresponding to the optical rotation of the sample. This signal after passing through the selective frequency circuit and power amplifier drives the servo-motor & in turn the analyzer until the optical zero position is regained. The analyzer rotation is measured by an encoder and is displayed on the digital readout as the optical rotation of the sample. DIGITAL POLARIMETER CDP - 001 Manufacturer Supplier and Exporters * Measures optical rotation, specific rotation, concentration and sugar content. * Based on Optical Null principle. * Multiple readings and calculation of average value and standard deviation. * Measurement of dark samples upto 1% transmittance due to adjustment of high voltage supply to the detector in accordance with the darkness of sample.* RS-232 interface. * Large backlite LCD display. * Various types of sample tubes, Sample tube length : 100 mm or 200 mm* Software for computer interface (Optional)
