EziLab supplies the Visible Spectrophotometer EZL-VS101 for chemical and food testing laboratories that need visible-range absorbance measurement without the UV capability built into the UV-Vis models elsewhere in this catalog. Covering 325-1000nm at 2nm bandwidth, this vis spectrometer measures color and concentration in samples that read within the visible spectrum, a narrower and typically lower-cost scope than a full UV-Vis instrument for labs that never actually need the UV range. That 325-1000nm span omits the UV region below 325nm entirely, which matters for buyers deciding between this and a UV-Vis unit — food colorimetric testing, dye concentration analysis, and general visible-color measurement work don't require UV detection, so a visible-only instrument covers those applications without the added cost of UV-capable optics and lamps that would go unused. Food and beverage quality programs testing color-based parameters, along with chemical labs running routine visible-range concentration checks, get full functional coverage from this narrower range at a more accessible price point than stepping up to a UV-Vis system built for a broader scope of pharmaceutical or research work. See the Vis Spectrometer and Visible Spectrophotometer ranges for visible-range absorbance testing needs across USA chemical and food testing laboratory settings.
