Atago Semiautomatic Polarimeters Polax-2L
The ATAGO Model Polax-2L Semiautomatic Polarimeter is the ideal instrument for measuring the optical activity of both inorganic and organic compounds. A compound is considered to be optically active if linearly polarized light is rotated when passing though it.
Easy to use Semiautomatic The rotation switches have both fast and slow push-button modes. The fast mode allows the Polax-2L to be quickly adjusted to an approximate reading by continuously rotating the analyzer. The slow mode allows the Polax-2L to be accurately adjusted by rotating the analyzer 0.05 (0.1Z) at a time Digital Accuracy High resolution and accuracy provide substantial precision for the testing of optically active solutions. The digital display and push-button operation both enhance overall precision -- no dials to turn, no vernier scales to read Electronic Temperature Measurement Features a temperature measurement range of 0.0-50.0 C for the sample chamber; it's displayed on the LED display with the push of a button Two Measuring Scales For flexibility, Model Polax-2L comes equipped with both Angle of Rotation & the International Sugar Scale LED Light Source The long-lasting LED light source with a 589nm interference filter is intended to last the life of the instrument. Automatically turns off when the unit is left inactive for a period of more than 5 minutes Wide Range of Industries & Applications Sugar Refineries, University Research, Flavors, Fragrances, Essential Oils, Identification and Characterization of Chemicals, Sugar Concentration & Purity in Food Products Sample Tubes Two end-fill sample tubes (100mm & 200mm) are included with the unit. The 200mm tube permits higher accuracy when used with transparent liquids, while the 100mm tube should be used with cloudy samples containing impurities. The tubes also contain a bubble trap which prevents errors caused by air bubbles in the sample. When only a small amount of sample is available for measurement, on optional micro sample tube (100mm, 1.0-1.5ml) is available
