Used BAUSCH & LOMB Spectronic 21 #9350267 for sale

BAUSCH & LOMB Spectronic 21 is a spectrophotometer used in a range of scientific research and analysis. Spectrophotometers are instruments used to measure the intensity of light, and Spectronic 21 allows for the measurement of intensity at different wavelengths of light. BAUSCH & LOMB Spectronic 21 is an all-in-one design, incorporating light source, monochromator, adjustable slit, detector, and display. The light source is a quartz-halogen lamp module that can generate light in wavelengths from 190-1100 nm with a combination of filters. The monochromator works with the light source, filters, and adjustable slit to allow the user to set the wavelength of light to be measured. The detector passes the light through a light crystalline device which as it is passes through it breaks up the light into its individual wavelengths. The individual wavelengths are then measured by a photomultiplier detector which measures the light intensity at each wavelength and sends the information to the display for the user to see. Spectronic 21 comes with a variety of options, including a multi-band detector and two cuvette holders, which can be used to measure absorbance and transmittance of various samples. BAUSCH & LOMB Spectronic 21 is a very versatile instrument, and can be used in a variety of applications, including chemical analysis, DNA and protein identification, environmental testing, medical diagnostics, and more. Spectronic 21 is a very user-friendly device, and its control panel includes a lamp intensity control, a cuvette changer, operation controls, and more. The built-in computer allows for automatic operations such as a data entry and recall, a keyboard for data input, and a real-time monitoring of the experiment. Overall, BAUSCH & LOMB Spectronic 21 is a reliable and versatile spectrophotometer, perfect for a range of scientific applications.
