Open the catalog to page 1A sensitive nondestructive technique for measuring the optical activity exhibited by inorganic and organic compounds. A compound is considered to be optically active if linearly polarized light is rotated when passing through it. The amount of optical rotation is determined by the molecular structure and concentration of chiral molecules in the substance. Each optically active substance has its own specific rotation as defined in Biot's law: The polarimetric method is a simple and accurate means for determination and investigation of structure in macro, semi-micro and micro analysis of...
Open the catalog to page 2Measurement Modes The Autopol IV can read directly in one of four measurement modes: Optical Rotation, Specific Rotation, Concentration or Specific Rotation Plus. Specific Rotation Plus allows a correction to be applied to a result for loss on drying. Each measurement mode can be activated via touchscreen selection. Sample cells Concentration is entered as a percentage. Temperature Control is allowed through rubber gasketing in the Autopol door which permits tubing to be connected from an external temperature controlled Water Bath to the jacket of a jacketed polarimeter sample tube. (See...

This accuracy is fine for food and educational applications where budget is critical but state of the art quality is still important. The Autopol I is not a pharmaceutical grade polarimeter and does not come with IQOQ (Installation Quality Operation Quality) documentation. Rudolph’s entry-level pharmaceutical and research grade polarimeter has ± 0.002 Degrees Optical...

It is the system of choice for research universities, pharmaceutical and fine chemical research departments. This instrument is also excellent for studying racemics and kinetics. Temperature control may be accomplished through a circulating Water Bath or with Rudolph’s optional Patented TempTrol™ System, which electronically heats and cools the sample to a specified temperature...

While other manufacturers use Polaroid Plastic Dichroic Sheet Polarizers, Rudolph does not. Instead, Rudolph uses the same high quality Glan Thompson Calcite Polarizers in all its models. Measurement reports can be saved as an Excel or PDF file and edited quickly and easily. You can import logos and print your company’s customized “C of A” directly. Why are high quality polarizing prisms...
