Table top spectrophotometer LTS-A11

Table top spectrophotometer LTS-A11


Table top spectrophotometer LTS-A11 is a high performance spectrophotometer with test caliber side ward for different aperture direction then that of top port model. The solid samples (paper sheets, cloth) can be placed directly on the measurement port & particles like pellets, tablets, powder (dye, food powder, chemical powder), paste (thick paste, opaque samples can be placed in cube shape cells & then in the mouth of the measurement test. Equipped with ETC technology solves the problem of long-term stability.
