Choosing an Instrument for Pharmaceutical Laboratories

Below is an example of why Polarimeters with accuracy of ±0.02 and ±0.01 accuracy polarimeters are not suitable for pharmaceutical applications. Please review the USP monograph for the material Ofloxacin. In addition, Ofloxacin must have a specific rotation between +1° and -1° at a concentration of 10mg per ml. Biots Law:

The Autopol I has an accuracy of ±0.02° optical rotation. For example, below is how its relative accuracy affects a hypothetical Ofloxacin sample:

You cannot successfully inspect a pharmaceutical (such as Ofloxacin) having a Specific Rotation between+1 and ±1 and a 1% concentration, which is quite common for most pharmaceuticals, with a polarimeter instrument that has an accuracy of ±2.0 in Specific Rotation.
In addition, the Autopol IV has an accuracy of 0.002 for Optical Rotations of 1°Arc for a total unknown of +/-0.002 under the same conditions:
