Persee T8DS Spectrophotometer UV/Vis Reader, Persee (CAT#: STEM-S-1441-LGZ)

The manufacturer of Persee T8DS Spectrophotometer UV/Vis Reader is Persee. Model is T8DS. The T8DS is a high performance dual beam scanning spectrophotometer with variable spectral bandwidth. Czerny-Turner monochromators with holographic gratings keep stray light to a minimum and provide excellent optical resolution. The use of photomultiplier tubes as detectors provides extremely high sensitivity. True dual beam optics coupled with an efficient and well-proven electronic control system with high stability and low background noise.
