About Vee Gee C25L Full-Circle Manual Polarimeter With
Description The VEE GEE Model C25L Manual Polarimeter features a full circular scale of +/-180 degree. With the use of the Vernier scale, rotations can be measured to an accuracy of 0.1 degree (an experienced user can potentially achieve accuracy of 0.05 degree). The rugged design allows for heavy use at the instructional level. Measurements are made by rotating the Vernier scale disc with the coarse/fine controls; which, in turn, adjusts the analyzer. The large diameter of the Vernier scale disc allows for highly sensitive comparisons of half shadows resulting in accuracy typically not possible with manual polarimeters. The optical assembly (Vernier scale disc, polarizer, analyzer, and sample compartment) is tilted 15 degree from horizontal. This results in more convenient and comfortable operation. The polarizer is fitted with a thin, high-quality, 2-part quartz disc which produces the divided (2 half shadows) field of view. When the 2 half shadows are viewed during measurements, right-shadow shading indicates a dextrorotatory sample and left-side shading indicates a levorotatory sample. Model C25L features a long-life, energy-efficient LED light source with a 589nm filter. 100mm and 200mm sample cells are included with each polarimeter. Specifications: Measuring scale: degree arc. Resolution: 0.1, accuracy: +/-0.1. Optical wavelength: 589nm. Sensitivity: up to 99.9% light absorption. Power requirements: 110/220V AC, 50/60Hz. Polarimeter's weight: 5.2 kg. Polarimeter measures 460mm length by 140mm width by 330mm height. Applications: education/instruction, quality control of original, intermediate, and final products, analysis of optically active compounds. Markets: food, beverage, sugar, clinical, medical, pharmaceutical, cosmetic and chemical.
