Spectrophotometers
The spectrophotometer, built by advanced manufacturing processes, is one of the main diagnostic and research instruments developed by humans. It is used in the laboratory to determine the concentration of a substance in a solution, allowing quantitative analyzes.
As we know, use the properties of light and its interaction with other substances to determine the nature of these. In general, light from a special characteristic lamp is guided through a device that selects and separates light from a certain wavelength and passes it through a sample. The intensity of light leaving the sample is captured and compared with the intensity of light affecting the sample and from it, the transmission of the sample is calculated, which depends on factors such as the concentration of the substance.
Types of Spectrophotometers a Laboratory may need
Double Beam
They adopt double beam long light path design to ensure the stability and accuracy; They are the best choice of high quality spectrophotometers.
Light path design: double beam
YR01864 series double light path design can prevent circuit fluctuation and stray light to ensure stability of the instrument.
Powerful software functions
Multi functions like spectrum scanning, standard curve, kinetics, multi wavelength scanning, DNA/Protein testing can be operated directly on the pc.
Long path light design
YR01864 series’ unique 520mm long light path design greatly improved resolution and the bandwidth can reach 0.5nm.
Unique beam
The instrument uses a lead screw structure so that the instrument wavelength accuracy and wavelength resolution can be greatly improved.
Auto setting wavelength
Users set wavelength automatically through arrow keys to avoid operation errors.
Numerical Keys
With microprocessor controlled, all parameters of the instrument can be easily set by numerical keys.
Data output
Equipped with USB port to connect with a PC to display spectrum scanning, kinetics and multi wavelength testing results on the screen through the optional software.

Importance of a Spectrophotometer in a Laboratory
The importance of a Spectrophotometer lies in the fact that it is used in the laboratory for the main purpose of diagnosing, taking into account the properties of light and the interaction with other substances. In general, this equipment is composed of 4 main parts: a source, a monochromator, a beam splitter, a sample area and a detector. It also has optical elements such as lenses or mirrors, which transmit light throughout the entire equipment.
