pharmaceutical polarimeter VariPol is ideal for pharmaceutical applications; circle polarimeter Polartronic V is an all-rounder for high-performance measurements; sugar polarimeter Saccharomat V excels in sugar polarimetry; fully automatic digital polarimeter Unipol V is designed for chemical applications, food and beverage, and cosmetics.
A polarimeter is a scientific instrument for measuring the quantity of light received at a specific point. This depends on what direction or polarization the various light waves may have in reaching the source. The process of the polarization of light was first discovered in 1808 by Etienne-Louis Malus, a French physicist, while one of the .The MCP polarimeter series complies with national and international standards such as pharmacopoeia, GMP, GLP, GAMP 5, OIML, and 21 CFR Part 11. Its built-in PC can capture different data (e.g. measurement results, audit trail, check / adjustment data) and the data storage can be deactivated for use according to USP <1058>. .

In this chemistry science fair project, you will make a homemade polarimeter. A polarimeter is a scientific instrument that precisely measures the angle of polarization and the brightness of light. Investigate the ability of glucose to rotate the plane of polarized light, using a flat-panel computer screen as the source of polarized light. An easily constructed and inexpensive polarimeter with an optical rotation angle resolution of about 0.5° is presented. It is made from small pieces of polarizing film, 2 LEDs, a protractor, and a few wires, all held in place with plastic interlocking toy bricks, such as Lego bricks. The instrument was used to demonstrate the optical rotation of plane polarized light as .
Step 1: Turn On the Polarimeter. Before you begin, ensure that the polarimeter is connected to a power source and turned on. Allow the light source to warm up for a few minutes to stabilize the intensity and wavelength. This is particularly important if the device uses a sodium lamp, which can fluctuate if not properly warmed up. .They now have the option of automated data capture, variable wavelength and temperature.
