Used BAUSCH & LOMB Spectronic 20 #9233879 for sale

BAUSCH & LOMB Spectronic 20 is a spectrophotometer first released in 1964. It is an advanced multi-wavelength absorbance spectrophotometer capable of measuring light intensity in the visible and near-infrared spectra. Spectronic 20 achieved certified accuracy for quantitative analysis of readily available absorption standards in the product literature. At its heart, BAUSCH & LOMB Spectronic 20 consists of a light source chamber, a sample chamber, a single monochromator, and a photocell. The light source chamber houses a xenon arc lamp and a filter wheel, which holds various color filters that allow the user to select a single wavelength or emission line. The sample chamber is enclosed in a metal housing and contains the sample compartment, a sample holder, and a detector. The monochromator consists of a double-prism system and a grating device that transmits light of specific wavelengths, located between the sample and the photocell. Spectronic 20 features a numerical readout for measurement of multiple wavelengths, with a maximum illumination time of roughly 6 seconds. As a spectrophotometer, it is equipped with a variety of accessories that aid in its operation, such as an external spectrometer, a colorimeter, and a range of external detectors. Furthermore, it is compatible with a range of sample holders that allow for flexibility in cell size, shape, and mounting. To use the spectrophotometer, the sample is placed in the sample chamber and the light intensity at the desired wavelengths is measured and displayed on the numerical readout. The spectral range can be adjusted by adjusting the filter wheel and prism settings. This allows the user to select the desired wavelength or emission line. The user can also adjust the integration time to increase the accuracy of the measurement. BAUSCH & LOMB Spectronic 20 has been widely adopted by laboratories, universities, hospitals, and other research and diagnostic organizations. It is an invaluable tool for a range of applications, including protein and enzyme analysis, determination of the concentration of various chemical solutions, and commercial product testing. The classic design, robust features, and custom accessories make Spectronic 20 a versatile instrument that is suitable for a diverse range of applications.
