Used VERNIER VSP-UV #293603448 for sale

VERNIER VSP-UV is a spectrophotometer designed to measure the spectral response of samples over a range of light frequencies. It is intended for use in various areas such as chemistry, biology and materials science research, as well as in educational studies. The machine operates by shining a light sample of a predetermined wavelength through a sample cuvette, or other sample holder, before passing the light through a monochromator. The monochromator splits the light into various individual light components and focuses them upon a detector. Once the detector has captured the light components, the electrical voltage generated by the detector is read to obtain the absorbance characteristics of the sample. VSP-UV features a double-beam design, meaning it has two light beams; a reference beam and a sample beam. This helps to increase accuracy and improve repeatability as measuring both beams allows for a higher accuracy measurement of the optical density reading. It has also a 'blank' port, for making a reference measurement of the raw light source, which is a useful feature for ensuring accuracy in the reading of the sample. The spectrophotometer is capable of recording light readings from 190nm to 900nm on the UV/VIS spectrum, with high resolution performance and sensitivity over a wide range of the spectrum, including UV and visible light. The device is easy to use and provides a quick and accurate method of measuring absorption spectra. A large color display with a graphical user interface, makes it easy to control and monitor the absorbing properties of the sample or other substances being measured and ensures that measurements are taken reliably, even over extended ranges of wavelength. The machine is also equipped with an array of safety features which help to protect the user, such as timers and warnings for over-exposure and short-circuiting. Overall, VERNIER VSP-UV is a reliable and versatile piece of technology which is capable of accurately measuring and recording light absorbance in a sample material. It provides a simple and safe method of quantifying minor spectral changes in a sample and is ideal for use in many areas of chemistry, biology, and materials science.
