Double Beam UV-Visible Spectrophotometer LB-13DBS

Name: Double Beam UV-Visible Spectrophotometer LB-13DBS
Brand: Labotronics
SKU: LB-13DBS
Rating: 4.9 (584 reviews)

Double Beam UV-Visible Spectrophotometer LB-13DBS is a light intensity measuring unit with deuterium lamp for prevention of ozone inhalation. The SiO2 coated optical mirror enables uninterrupted propagation of light and reduces contamination through external sources. It is characterized with double and triple wavelength test feature for measurement of transmittance and absorbance.
