Product Details

Unico UV Visible spectrophotometer UV-4802S

The UV-4802 adopts a dual beam design and is an independent model with a fixed bandwidth of 1.8 nm, integrating all the functions of the SpectroQuest series independent models. The instrument is equipped with two detectors that can measure the sample and reference separately and synchronously to optimize measurement accuracy. It has excellent measurement performance in the wavelength range of 190 nm to 1100 nm, suitable for pharmaceutical, biochemical, and clinical laboratory applications. It can also meet the conventional application needs of quantitative analysis, kinetic research, spectral scanning, multi-component analysis, and DNA/protein detection. Optional computer data download software and Windows system application software are available, making the instrument's functions more diverse.

Main functions

Basic Mode

Measurement of absorbance, transmittance (% T), and concentration

quantitative analysis

Establish or call stored calibration curve equations for concentration determination of unknown samples

Wavelength scanning (WL scanning)

Spectral scanning of samples can be performed within any selected wavelength range, supporting the selection of scanning speed and wavelength interval. Scanning speed options include low speed, medium speed, or high speed

kinetic analysis

Measure the change of absorbance over time and have the function of calculating reaction rate

DNA/protein analysis

Calculate DNA/protein concentration and DNA purity, and also measure ratios at other wavelengths

Multi wavelength analysis

Analyze and determine the composition of the mixture through multi wavelength measurement

Custom testing

Open platform that supports the use of custom programs and can store multiple testing plans
