The design specifications of the new UV-1800 UV-VIS spectrophotometer meet the requirements of the Japanese and European Pharmacopoeias, with a resolution of up to 1 nm, high performance, compact design, and convenient use. At the same time, it can be used as a standalone instrument or as a computer-controlled instrument.
High resolution -1 nm
UV-1800 has high resolution and can easily meet the wavelength resolution standards required by the European Pharmacopoeia. In addition, it is also equipped with a Cheney Turner spectroscopic system, making the optical system more compact and bright. Scattered light, wavelength repetition rate, and baseline repeatability have been simultaneously enhanced, suitable for user needs.

Space saving design
The width of UV-1800 is only 450 mm, making it one of the smaller and more compact instruments in its class, allowing it to be configured in small spaces. Compared with UV-1700, the configuration space has been reduced by 15% and the width has been reduced by about 20%.
The UV-1800 is equipped with different measurement modes and multiple functions that are standard in a single machine instrument, allowing for a wide range of detection, including photometry and quantitative analysis of proteins
Photometric measurement mode
Measure the absorbance/transmittance of a single wavelength or multiple wavelengths (8 wavelengths). When measuring multiple wavelengths, up to 4 wavelength data can be calculated for dual wavelength differences/ratios.
Spectral mode
Use wavelength scanning to obtain sample spectra. Repeated scanning can track the changes in the sample over time. The measured spectrum can be subjected to data processing such as amplification/reduction, peak detection, etc.
Quantitative mode
Create a calibration curve from standard samples and calculate the concentration of unknown samples. Various combinations of wavelength numbers (1-3 wavelengths, differential values) and calibration curves (K-factor, 1-3 times) can be used.
Dynamic mode
The change in absorbance was measured as a function of time to obtain the activity value of the enzyme. You can choose between dynamic detection methods and ratio detection methods. By using this mode and combining it with the MMC-1600/1600C multi cell rack (8/16 series multi battery) instrument or the CPS-240A rack (6 cells), continuous testing of multiple samples can be performed.
Time scanning mode
Measure the changes in absorbance, transmittance, or energy over time at a specified wavelength. Use multi cell rack MMC-1600/1600C (8/16 series multi cell) instrument combined with CPS-240A cell rack (6 cells) to ensure analysis of multiple samples.
Multi component quantitative analysis mode
Quantification of each component can be performed on a mixed sample of 8 components, and pure or mixed standard samples can be used as standard samples.
Biological mode (standard)
The following quantitative analysis methods can be used to analyze DNA and protein substances. Nucleic acid quantitative analysis - can use absorbance at wavelengths of 260/230 nm to 260/280 nm to quantify DNA or proteins Protein quantification Lowry method BCA method (using diquinolinecarboxylic acid) CBB method (Coomassie Brilliant Blue G-250) Biuret method UV absorption method (direct detection at 280nm wavelength)
Security function
The UV-1800 security feature can limit usage based on user level restrictions.
Instrument verification function
UV-1800 is compatible with 9 JIS projects. Including wavelength accuracy, wavelength repeatability, resolution, stray light, photometric accuracy, photometric repeatability, baseline flatness, baseline stability, and noise.
maintain
The working time of deuterium (D2) lamps and halogen lamps (WI) can be recorded and displayed. Therefore, the replacement cycle of the lamp can be confirmed during regular maintenance.
