A guide for product comparison by type and application
Colorimeters: Standard and microprocessor-controlled units with built-in wavelength filters display concentration directly.
Visible Light Spectrophotometers: Simple spectrophotometers use only visible light (380 to 750 nm) produced by a tungsten lamp. Portable and benchtop models with a continuous wavelength range are most commonly used for routine laboratory work. Choose from analog and digital models that feature optional data acquisition software for your PC.
UV-Visible Spectrophotometers: A second lampusually deuteriumturns a visible light spectrophotometer into a UV-visible unit that can measure from 190 nm to 750 nm. UV-visible models are available with a variety of features, including scanning, multiple cells, integral printers, and user interfaces.
Fluorometers: Fluorometers measure the fluorescence released when a sample is exposed to a single wavelength of light. Select one of our compact and efficient fluorometers for unlimited analysis testing in biotechnical, pharmaceutical, and environmental applications.
Infrared Spectrophotometer: Some applications in teaching and research environments require the measurement of solid, liquid, and gas samples. Our scanning infrared spectrophotometer provides data over a full range of wavelengths from 4000 to 600 cm-1 in seconds.
Mercury Analyzing Spectrophotometer: An economical alternative to atomic absorption systems, our mercury analyzing spectrophotometer quickly measures trace amounts (0 to 9 µg) of mercury in potable, surface, saline, or waste water.
Atomic Absorption Spectrophotometer: A high-temperature flame evaporates water and dissociates the sample into ions. These features allow for high-precision analysis in environmental testing, toxicology, and Q.C. laboratories. An optional continuous-flow hydride/cold vapor system lets you test for arsenic, selenium, or mercury.
