Manufacturer: Thomas Scientific Brand: LABOMED Model: Spectro 24 RS

The Labomed Spectro 24RS single-beam visible-light spectrophotometer has a multi-cell receptacle to measure transmission, absorption, concentration, and factor for routine spectro-analysis in a range of applications and industries, including chemical, biochemical, agriculture, environmental protection, and education. The instrument has a 320 to 1,100nm wavelength range for use in the visible, near-ultraviolet, and near-infrared spectral range. It has a 0 to 100%T transmittance range, 0 to 1.999A absorption range, and 0 to 2,000C concentration range. The 4nm bandwidth provides more consistent results for low-concentration samples than does 1nm. It has a tungsten-halogen lamp, a silicon photodiode detector for reduced noise, and a monochromator with a 1,200 lines/mm grating mirror. A built-in stray-light filter increases accuracy. 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 round test tubes and up to four 10 x 10mm square cuvettes. Capacitive-touch buttons ease cleaning and prevent liquids from entering the device. An RS-232C interface enables data to be transferred to a computer (sold separately). The instrument has a switch that allows the customer to choose between 110VAC/60Hz and 240VAC/50 power sources.
