Polarimeter

(Automatic polarimeter, manual polarimeter, semiautomatic polarimeter, spectrophotometer, spectrum instrument, optical analytical instruments)

WXG-4  FULL-CIRCLE MANUAL POLARIMETER
WXG-4 manual polarimeter is ideal for determining concentration levels of samples for applications in the medical, educational, pharmaceutical, and cosmetic industries etc.
 
Easy Measurement:
The polarimeter with 589.44nm monochromatic sodium lamp. After powered on, the polarized light beam is immediately project on filter, polarizer etc.
You can view the visual 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 20oC.

Purity Measurement:
The polarimeter is ideal for determining purity of sample. If you want to know its purity, you need only measure its the angle of rotation and calculate it.

Concentration Measurement:
For some substance of known specific optical rotation, you can measure its the angle of rotation and calculate concentration according to formula.

International Sugar Scale:
According to international sugar scale, put the 26g pure sugar in solution, The angle of rotation of solution is 34.626o. By the rules, you can calculate
the purity of sugar.

What's included:
100/200mm tube, Sodium lamp.

WZZ-2A  AUTOMATIC POLARIMETER
WZZ-2A automatic polarimeter is the basic scientific instrument used to measure angle of rotation, specific optical rotation of optically active substance. 
 
Automatic Measurement:
WZZ-2A 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:
100/200mm 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.
