紫外可见分光光度计
Pharmaceutical assays, water testing and protein quantification all start on a reliable UV-Vis. This spectrophotometer scans 190–1100 nm with a 2 nm bandwidth and ±0.3 nm wavelength accuracy, using deuterium and tungsten-halogen lamps. Photometric accuracy is ±0.003 A at 1 A, with stray light at most 0.05% T at 220 nm. Let us know which cuvette holders you need.
