Perkin Elmer Model 341 is a precision digital polarimeter that comes with Na and Hg source lamps and Glan-Taylor polarizer. It can be extended into the UV and is ready for polarimetric HPLC detection. This 341 Polarimeter uses the proven optical null principle and microprocessor electronics: a highly precise instrument that is easy to use for quality control and research work as well.

System Specifications: Microprocessor electronics, built-in mercury (Hg) and sodium(Na) lamps, wavelength selection by turret-mounted filters (589 nm/NaD, 578 nm, 546 nm, 436 nm and 365 nm spectral lines). Four positions for additional mercury line filters. Two selectable aperture stops for standard cells and microcells. UV-transmitting Glan- Taylor calcite polarizer prisms. Optical null system with automatic rotation of the analyzer, range of rotation /- 85 . Internal angular resolution: 0.0001 . Display of results in angular degrees, as specific or molar rotation or in Z of the International Sugar Scale and with user defined factors. Automatic gain control, digital signal averaging with 10 selectable integration periods. Menu-oriented u
