The spectrophotometer is an instrument used by spectrophotometry to measure the amount of light intensity absorbed after passing through a sample solution. There are several types of spectrophotometers. These are grouped according to the type of sample analyzed; there are atomic absorption and molecular absorption
This instrument has the ability to project a beam of monochromatic light through a sample and measure the amount of light that is absorbed by that sample. This allows the operator to perform two functions, one of which is to provide information about the nature of the substance in the sample and the other is to indirectly indicate how much of the substance of interest is present in the sample.
Spectrophotometers are color measurement devices used to capture and evaluate color. As part of a color control program, brand owners and designers use them to specify and communicate color, and manufacturers use them to monitor color accuracy throughout production.
In general, for a spectrophotometer to function properly, it always requires an electrical supply source in accordance with the norms and standards implemented in the country, a dust-free environment, and a stable work table away from equipment that generates vibrations such as centrifuges. or stirrers. But its conservation largely depends on the way of installation and use. The environment that surrounds them and the quality of the electricity services are factors of primary importance, so that the equipment can provide the services in accordance with the specifications for which they were manufactured. The maintenance routines that may be required, vary in complexity, ranging from the careful cleaning of their components to specialized procedures, which should only be carried out by technicians or engineers who have received the corresponding training and have the technical information developed by the manufacturers and that conform to the different models and designs available.
Spectrophotometer calibration consists of carrying out a set of operations whose purpose is to determine the magnitude of the errors that the equipment makes when making measurements, these errors are obtained by comparing the results of each measurement with certified values of a reference material, taking into account that the measurements were made under the same or similar environmental conditions and calibration place.
The calibration takes into account the quantification of errors and the uncertainty of the photometric scale and the wavelength scale. Which serve as a basis to know the state in which it is with respect to the manufacturer's specifications.

There are countless models, so it is normal that you do not know which laboratory spectrophotometers to buy that suits your needs. At Kalstein, we test them to find what you're looking for.
It is an analytical technique that allows to determine the concentration of a compound in solution, the molecules absorb radiation
Spectrophotometers are instruments capable of analyzing the characteristic frequency spectrum of a wave motion.
They are a restructuring of double beam spectrophotometers; but instead of a cutter they use a beam splitter to send the light through the target
It was developed to compensate for these changes in lamp intensity between blank measurements and samples. In this configuration, the light source emits a single beam of light
It has an instrumental method of analytical chemistry that allows to measure the specific concentrations of a material in a mixture

The spectrophotometer is a piece of equipment used in the laboratory in order to determine the concentration of a substance in a solution, thus allowing analysis to be carried out
A spectrophotometer is a piece of equipment used in laboratories to determine what the beam of electromagnetic radiation or light is and thus identify, qualify and quantify its intensity.
The spectrophotometer quantifies the concentration of a specific substance that is present in a sample by comparing the amount of light that enters a sample compared to the amount of light that leaves the sample at a specific wavelength. It can be used theoretically to measure any substance that absorbs light.
