Used PERKIN ELMER FIAS 400 #293610104 for sale

PERKIN ELMER FIAS 400 spectrophotometer is an advanced scientific instrument used for measuring the absorption and transmittance of light across a wide range of wavelengths. It is used in a variety of applications, such as analyzing the composition of materials, measuring the optical components of various materials, and for optical density determination. FIAS 400 is capable of both absorption and fluorescence measurements, and has a wide dynamic range, allowing for both low level and high level measurements with a single device. PERKIN ELMER FIAS 400 utilizes a double beam design that provides excellent sensitivity, selectivity, and reproducibility. The light source is a tungsten lamp with a sharp cut filter, which produces a defined level of illumination, and a beam splitter that divides the light into two beams of equal intensity—one directed toward the sample and one directed towards a reference detector. A monochromator holds a selection of optical and interference filters, which can be individually rotated to the desired wavelengths. The light is received by an photomultiplier tube and converted into an electronic signal. FIAS 400 is highly precise, with a measurement range of up to four orders of magnitude. The sensitivity and selectivity of the system enables accurate and reproducible results even at low detection levels. Additionally, the system can be used for quantitative measurements of complex samples and systems. PERKIN ELMER FIAS 400 also includes a number of powerful tools, such as a kinetic processing unit for measuring time-dependent changes, and a flexible data collection software package for storing and analyzing data. Overall, FIAS 400 is an advanced spectrophotometer that provides reliable, reproducible results across a wide range of wavelengths. It is precise and can rapidly analyze samples, making it suitable for a variety of professional scientific applications. Additionally, the system includes powerful software tools for accurate data analysis and manipulation.
