Euromex E99-400-LED Novex Polarimeter with LED

Features:

• Fast and accurate
• Short warm-up time
• 589.3nm high-power LED lamp
• 100 and 200mm observation tubes are included

Applications:

• Polarimeters are frequently used for process control of chemical, pharmaceutical, and food research labs of production facilities
• Some substances that can be measured are: steroids, diuretics, antibiotics, drugs, vitamins, analgesics, amino acids, essential oils, sugars

The purity and concentration of optically active substances can be determined with a polarimeter. An optically active substance will rotate the polarization plane of linearly polarized light. The amount of rotation depends on the molecular composition and is proportional to the concentration of chiral molecules. Each optically active substance has its specific rotation factor as defined by Biot's law

• The polarimeter is a sensitive instrument for non-destructive measurement of the optical activity of or-ganic and inor-ganic substances
• It is also a simple and cheap method for expensive or non-replicable samples
