Our polarimeter P1000-LED is used by numerous companies and institutes for basic lab applications and training, for example the experiment on saccharose inversion. It measures the optical rotation according to the half-shade principle, and the measurement results are read through an eyepiece and two noniuses. Basic laboratory applications Sample chamber for measurement tubes with a length of up to 220 mm Requires only little maintenance due to a high performance LED whose service life is up to 2000 times longer than that of conventional sodium discharge lamps The scope of delivery includes two measurement tubes (100 and 200 mm length) with a debubbler for the proper filling. Can be validated due to the possibility of receiving quartz control plates for the calibration and adjustment.
