  • Performance feature

  • l Standard automatic 4-position cell holder, optional seven-position or 16-position cell  holder

  • l Light source correction mechanism, the light source will be locating the best position when self-testing each time so that it can fix the offset focus position possibly caused by vibration during the transportation and the user don’t have to debugging light source after change it

  • l The models that pursuit of cost-effective introduced by customers, there are two configurations of host and software control. The instrument equipped with precise split beam optical system and rational design of circuit control section.

  • l Built-in SCM technology and qualitative & quantitative analysis software enable TU-1810PC UV-Vis spectrophotometer realize automatic control, data acquisition and processing, spectroscopy, kinetics measurement, quantitative analysis, DNA and spectral scanning etc functions.
