Spectro 23 RS

Spectro 23 RS spectrophotometer is a visible and near ultraviolet spectral range, with high technology of built-in interface RS-232C, to make it possible to communicate with any IBM compatible computer and printer for test documentation as well as to store, record, and print test results. Spectro 23 RS utilizes new generation technology; using a microprocessor for automatic adjusting of 100% T and Zero absorption, Factor and Concentration. Most knobs have been eliminated and replaced by Soft Key, as a result; Spectro 23 RS is really easy to work with.

The Spectro 23RS spectrophotometer can be used at chemistry analyzing, biochemistry labs and clinical laboratories. It can also be utilized for environmental protection, quality control, agricultural research and industries.

The 4 multiple cell holder is one of the unique features of the Spectro 23RS. It is able to test, record, and print four sample results immediately by built in interface RS-232C. Furthermore, Spectro 23RS may save the reagents and samples by using the optional semi-micro cuvette of 1.5 ml or less to help reduce waste.
