Lab Expo Tabletop spectrophotometer 15A-TTS102 is a high-performance spectrophotometer with upward test caliber (top port). 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 a round shape plate & then in the mouth of the measurement unit.
