UV2300ultraviolet/Visible spectrophotometerProvides high performance, easy to use and reliable, with a wide range of applications. The resolution of 1.5nm meets the standards of the European Pharmacopoeia. In biochemical applications, it is possible to measure very small amounts of samples such as DNA, and a micro pool of 50ul can be selected.
UV2300ultraviolet/Visible spectrophotometercharacteristic:
High resolution monochromator;
UV2300 can achieve higher resolution due to the elimination of coma aberration in the Seya Namioka monochromator. The Seya Namioka monochromator is the most commonly used concave diffraction grating today. The diffraction grating in UV2300 was manufactured using a high-precision grating engraving machine from Japan
Better spectral bandwidth
The spectral bandwidth is 1.5mm, which meets the standards of the European Pharmacopoeia and enables more accurate measurements.

USB storage for storing and exchanging data
The UV2300 host has a built-in USB interface and File Manager file management software for data exchange. This interface can connect multiple brands of USB flash drives (USB flash drives) with large storage capacity, making it convenient for storing information.
Optical systems have strong energy and good stability
Dual beam dual detector design, good stability, short startup preheating time. Due to the presence of two detectors, light loss is reduced, light energy is stronger, baseline noise is lower, and analysis sensitivity is improved.
640 × 480 high-definition LCD display
The calibration curve spectrum and test results can be displayed on a 640 × 480 high-definition LCD monitor, and the soft background light makes the displayed content easy to observe. The keyboard buttons are cleverly designed, allowing users to use fewer keys to complete desired operations and improve efficiency.
Featuring multiple measurement modes such as wavelength scanning
Measurement of photometric values: Concentration can be calculated using a line or multiple regression line as a calibration curve.
Wavelength scanning: After measurement, the spectrum will be displayed; Various data processing techniques can be used; Repeated scanning can track the chemical reaction process.
Time scan: displays the variation of its luminosity value over time at a single wavelength. This function can be used for enzyme reaction analysis. There are also various data processing techniques in time scanning.
Multi wavelength photometric measurement: It can automatically perform tests for up to 6 wavelengths. If the required data is measured at a specific wavelength, full wavelength scanning can be avoided to achieve rapid measurement.
Full wavelength fast scanning
The spectrum covers the ultraviolet/visible range of 190-1100mm, with a scanning speed of up to 3200nm/min. Whether it's scientific research or quality control for designing large quantities of samples, UV2300 can handle it with ease.
Microcell system suitable for biochemical measurement
*The optical design of the instrument ensures that it can use a 50ul micro cell device for micro sample analysis, especially in medical, biochemical experiments, and valuable sample testing.
Built in 260/280nm ratio measurement function
The determination of the 260/280nm ratio can be used for quantitative analysis of nucleic acids.
GMP/GLP Wizard Function
The built-in GMP/GLP wizard function can help users easily complete various operations required by GMP/GLP. Automatically record the time when the light is on. The lighting time of deuterium lamps, tungsten lamps, etc. is automatically recorded in the instrument's memory, and users can decide whether to replace the light source based on the displayed time consumed by the lamp.
Fixed slot positioning light source
When replacing the light source, simply plug it into the lamp holder without adjusting the light path. This way, even without the presence of manufacturer technicians, users can replace the light source themselves.
The confirmation function of the instrument can real-time determine the current condition of the instrument
UV2300 has a self checking function, which can ensure that the instrument operates under the best conditions. Parameters such as wavelength accuracy and early sound level can also be checked.
Confirmation function: This function checks and confirms the performance of the instrument. Compare the measured value with the preset value. The parameters being checked are as follows: wavelength accuracy
（656.1nm)、 Wavelength accuracy (486.0nm), wavelength repeatability, bandwidth, baseline smoothness, baseline stability, noise level.
* Automatic calibration and diagnosis: During installation, many diagnostics and adjustments can be automatically performed, including memory checks, wavelength driver device checks, and wavelength accuracy checks at 656.1nm. Other automatic functions include using the D2 light to illuminate the line for wavelength correction. The lighting time of W1 and D2 lights can also be displayed to meet GLP requirements.
