WXG-4 Manual Polarimeter Language Option more Detailed Product Description Manual polarimeter is ideal for determining concentration levels of samples for applications in medical, educational, etc. WXG-4 manual polarimeter is ideal for determining concentration levels of samples for applications in the medical, pharmaceutical, educational and cosmetic industries etc. Easy Measurement: The polarimeter with 589nm sodium lamp. Switch on the power, the polarized light beam will immediately radiate to the polarizer, filter. You can observed distinct visual fields through eyepiece. Put the sample cuvette into measuring field chamber, and rotate the vernier knob, you will see an equal brightness. Reading and recording the measured value from vernier scale, the testing is completed. Specific Optical Rotation Measurement: Specific optical rotation is constant value of substance. Uses 100mm sample cuvette, and control sample at 20 Degrees Celsius, you can measures the sample of Specific Optical Rotation. International Sugar Scale: According to international sugar scale, put 26 grams pure sugar into solution, the angle of rotation of solution is 34.626. By above rule, you can calculate the purity of sugar. Specifications: Measurement Range: -180o ~ + 180o Scale Value: 1o Vernier: 0.05o Magnifier: 3X Light Source: Sodium Lamp Wavelength: 589.44nm Round Cuvette: 100 or 200mm Stable Time: 10 minutes Power Requirements: 220VAC/ 50Hz Dimensions: 500( L) × 135( W) × 330( H) mm Weight: 6.5kg Product Included: 100 and 200mm Round Cuvette, Sodium Lamp
