New disc polarimeter with sodium lamp +/- 180 degree,
WXG-4 Disc Polarimeter with Sodium Lamp
WXG-4 Manual Polarimeter is ideal for determining concentration levels of samples for applications in the medical,educational,pharmaceutical and cometic industries etc.
* Measurement: +/- 180 degree
* Power Requirements: 110V or 220V
The Polariment with 589.44nm monochromatic sodium lamp.After powered on,the polarized light beam is immediately projected on filter,polarizer etc.You can view the visua fields of brightness or shade through eyepiece.Rotate the vernier knob till the visual field to equal brightness.(Zero point).Put the sample tube in measuring field chamber.Rotate the vernier knob again,you can view equal brightness.Read the scale from magnifier that is measured value.
* Specific Optical Rotation Measurement:
Specific optical rotation is constant of substance,you can measure it by 100mm glass tube when temperature of solution at 20 centidegree.
The Polarimeter is ideal for determining purity of sample.If you want to know its purity,you need only measure its angel of rotation and calculate it.
* Concentration measurement:
For some substance of known specific optical rotation,you can measure its angle of rotation and calculate concentration according to formula.
* International Sugar Scale:
According to international sugar scale,put 26 grams pure sugar in solution,the angle of rotation of solution is 34.626 degree.By the rules,you can calculate the purity of sugar.
