23A spectrophotometer is designed for the purpose of education and general analysis in low cost, It can use Φ10-Φ16mm tube or rectangular cuvette in sample department, high reliable and operate easily. It can be used for environmental protection, education etc, qualitative analysis & quantitative analysis can be done.

​

1. The instrument has variable wavelength and four scales: transmittance absorbency concentration and factor.

2. Using universal test tubes or cuvette to make measure directly.

3. The instrument is micro computerized and easy in operation.

4. The 12nm spectral slit width provides the sensitivity required  for almost any application.

5. One solid-state silicon detector covers entire wavelength range, eliminating the need to change detectors between different  analysis.

6. It is easy to replace the unit of instrument specially the Unit of the Pre-adjusted light source, and make it convenient to maintain.

7. Free adjusting for filter exchange.

8. The grating and toroidal mirrors are selected in optical system
