UV visible spectrophotometer TGW-5800

Ø Introduction

The UV visible spectrophotometer can perform qualitative and quantitative analysis of sample substances in the UV, visible, and near-infrared spectral regions due to its continuous spectrum with a wavelength range of 190-1100nm. This series of instruments has a simple structure, stability, reliability, and accurate readings. They are widely used in various fields such as basic teaching in universities, medical and health care, clinical testing, petrochemicals, environmental protection, metallurgy, and electricity. They are commonly used analytical instruments in physical and chemical laboratories.

Ø Main Features

l The instrument adopts a 128 * 64 bit dot matrix LCD display, which displays clearly, reads accurately, and is stable and reliable

l It can directly establish standard curves and conduct relevant tests using standard curves. It can continuously test and store 200 sets of data, and can store 200 standard curves. Users can easily call them according to their numbers, and test data can be kept powered off

l Automatic wavelength calibration, automatic setting, and deviation self repair

l Flange based deuterium lamp design, no optical debugging required for lamp replacement

l Adopting an optical system suspension design, the overall optical path is independently fixed on an 8mm thick aluminum non deformable base. The deformation of the bottom plate and external vibrations have no effect on the optical system, greatly improving the stability and reliability of the instrument

l The optional 3D software from Yuanxi Company can directly complete photometric measurement, quantitative testing, qualitative testing, multi wavelength testing, DNA/protein testing, and data processing analysis
