Used VARIAN 3900 #9283986 for sale

VARIAN 3900 is a state-of-the-art spectrophotometer designed to measure the absorption and emission properties of light in a variety of applications. It utilizes a precision monochromator for extremely accurate measurements of the spectral power distribution of the light and optical filters for detecting specific wavelengths in the visible spectrum. The most common applications for 3900 include measuring the absorbance of samples, determining the emission spectrum of luminescent sources, and measuring the intensities of fluorescence and phosphorescence. VARIAN 3900 has a large spectral bandwidth from the ultra-violet region of the visible spectrum to deep infrared with full wavelength range performance between 180nm and 1050nm. The instrument incorporates an advanced design that incorporates a single beam path and optical components, meaning that it can be used for both absorbance and emission measurements without the need to switch between dedicated paths. Additional features include a six position turret that accepts up to six sample cells or cuvettes for simultaneous data acquisition or comparative measurements, as well as internal compensation for interference caused by the sample container. 3900 spectrophotometer is controlled and operated via a high-resolution color touch screen display, allowing simple and intuitive control over the instrument. All data can either be stored on the instrument's internal memory or can be transferred to a PC with the included data transfer software. The instrument also includes a selection of preconfigured methods and software tools which allow users to automate measurements, manage data, and generate sophisticated reports. The optical performance of VARIAN 3900 has been designed to meet the most demanding of applications, providing users with the highest accuracy and repeatability of measurements. The instrument utilizes an ultra-stable spectrometer with a variable slit size, allowing for a resolution of up to 0.2nm. This ensures a high-level of accuracy in the measurements, with repeatability typically better than 1 per cent relative. In addition to the performance of the instrument, 3900 also includes numerous safety features designed to protect both the instrument and the user. These features include a safety interlock on the power supply, an emergency stop switch, and a built-in alarm system to notify operators when any parameters exceed pre-defined levels. Overall, VARIAN 3900 spectrophotometer is an advanced and precise instrument providing users with professional-grade measurements for a wide range of applications. The instrument provides users with a powerful tool to measure the properties of light in the visible spectrum, ensuring a high level of accuracy and repeatability in their measurements.
