Manual polarimeter model P1000-LED

Analog polarimeter for basic laboratory applications and suitable for education. This model integrates a high-power LED, with a lifetime 2000 times longer than usual sodium vapor lamps. It measures optical rotation according to the penumbra principle, and the measurement results are read through an eyepiece and two verniers. Characteristics:

• Basic laboratory applications
• Sample chamber for measuring tubes up to 220 mm long
• Low maintenance thanks to a high-performance LED with a lifetime up to 2,000 times longer than conventional sodium discharge lamps
• Two measuring tubes (100 and 200 mm long) with a purification device for correct filling are included in the scope of delivery.
• Can be validated with quartz control plates for calibration and adjustment (not included, please consult).

• Use for practical exercises and experiments:
• Kinetics of cane sugar inversion
• Glucose Mutarotation
• Determination of polysaccharide concentration by amylolysis
