The Labomed Spectro UV-2502 UV and visible-light spectrophotometer has a multi-cell receptacle to measure transmission, absorption, concentration, and factor for routine quantitative analysis in a range of applications and industries, including chemical, petrochemical, biochemical, agriculture, environmental protection, and education. The instrument has a 190 to 1,100nm wavelength range for use in the ultraviolet and visible-light spectral range. It has a 0 to 100%T transmittance range, 0 to 1.999A absorption range, and 0 to 1,999C concentration range. The 2nm bandwidth provides lower detection limits and improved signal-to-noise performance. It has tungsten-halogen and deuterium lamps, a silicon photodiode detector for reduced noise, and a monochromator with a 1,200 lines/mm grating mirror. The instrument automatically calculates absorption, transmittance, factor, and concentration, and auto-zero and auto-calibration ensure consistent results. The spectrophotometer has a receptacle that accepts up to four 10 x 10mm square cuvettes and 13mm round test tubes (adapter sold separately). The LCD provides access to controls and test results, and the capacitive-touch buttons ease cleaning and prevent liquids from entering the device. An RS-232C interface enables data to be transferred to a computer (computer and software sold separately).

H is height, the vertical distance from the lowest to highest point; W is width, the horizontal distance from left to right; D is depth, the horizontal distance from front to back.

A spectrophotometer is a device used to measure and analyze aspects of light absorption in liquids and solids. Readings are displayed in digital or analog format. A spectrophotometer can have a handheld body for field use, or a bench-top body for laboratory applications. It may have one or more adapters to enable it to measure surfaces or liquids. A spectrophotometer is used for testing and measuring in anatomy, chemistry, agriculture, process plant, food and beverage making, homeland security, and educational applications.

Labomed manufactures spectrophotometers, microscopes, diagnostic instruments, and accessories for scientific and medical laboratories. The company, founded in 1980, is headquartered in Culver City, CA and meets International Organization for Standardization (ISO) standards 9001:2013.
