One of the most important quality control methods used in the pharmaceutical, chemical, cosmetics, food and beverage industry is polarimetry – optically active substances are analysed by determining their angle of rotation. The angle of rotation allows you to ascertain the identity and quality of substances as well as their concentration in mix tures. It can also indicate the progress of reactions and conversions. Polarimeters are used in a wide range of applications – from the determination of the purity and concentration of ingredients in pharmaceuticals to the maturity testing of agri cultural products to the measurement of the sugar
con tent in beverages and candies.

Indispensable for teaching and training

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.

Typical Applications

Hospitals and pharmacies:

• Incoming/outgoing goods inspection
• Control of pharmaceutical products according to pharmacopoeias

Training in the industry or at universities:

• Use for practical exercises and experiments:
• Kinetics of the cane sugar inversion
• Mutarotation of glucose
• Determination of the concentration of polysaccharides
  through amylolysis
