Used VARIAN 3300 #9127699 for sale

VARIAN 3300 spectrophotometer is a advanced scientific instrument designed for complex PCR, enzymology, and DNA nucleic acid research. It is a high-end, double-beam spectrophotometer capable of providing excellent sensitivity, accuracy, and precision for a variety of studies. The instrument is equipped with two sources of light - one to measure absorbance, and another to measure transmittance. The two beams of light are collimated and combined to provide a single beam for absorbance measurements. This beam is then passed through clear cuvettes which contains the sample solution and a reference cuvette to measure the baseline absorbance. The absorbance is measured with a photomultiplier tube, which converts the light into an electrical signal. This signal is then digitized for further processing and analyzed with the instrument's computer. The intensity of light received by the cuvette and the amount of light it absorbs is translated into a numerical output which is displayed on the instrument's interface. The instrument is very versatile and can be used for nm to ultraviolet spectroscopy measurements. It is capable of measuring molecules in excess of 3,000 Da in size and has a broad range of sampling options, from full-spectrum to single-wavelength analysis. Additionally, multiple accessories are available to extend the capabilities of the instrument, such as a chromogenic intensifier for measuring fluorescent samples. 3300 is the perfect tool for researchers seeking precise spectral data of organic and inorganic compounds. It can also provide comprehensive data sets for materials that are time-sensitive such as pharmaceuticals, which require quick analysis. With its wide range of capabilities and accuracy, it is one of the top choices for spectrophotometry and spectroscopy researchers.
