HZ-EU2600 Scanning Quasi-Dual Beam UV-Vis Spectrophotometer HZ-EU2600 190-1100nm Scanning Quasi-Dual Beam UV-Vis Spectrophotometer


HZ-EU2600series large-screen, scanning, dual-beam spectrophotometers have a friendly interface and easy operation. They include all the test functions of conventional spectrophotometers, with high precision and low noise, and can meet a wide range of application requirements such as daily analysis and scientific research.

II.Instrument function

◆ Photometric measurement: transmittance T%, absorbance Abs, energy E

◆ Quantitative test: concentration content C (coefficient method, standard curve method)

◆ Wavelength scan (spectral scan): scan range, interval and speed can be set

◆ Time scan (kinetics): measure the change pattern and calculate the reaction rate

◆ DNA/protein determination: ratio and concentration are displayed directly, and the method can be customized

◆ Multi-wavelength test: Simultaneously measure the results of multiple arbitrary wavelengths

◆ Other functions: system application, graph data processing, report printing, etc.

III.Instrument Features

◆ The quasi-dual beam ratio monitoring optical path can effectively suppress the drift of the circuit optical path, suitable for long-term testing

◆ Automatic wavelength calibration, automatic dark current and blank correction, automatic switching of light source and filter

◆ The large sample chamber can accommodate 5-100mm cuvettes and support accessories required for various tests

◆ High-quality optical and electronic components ensure high precision, low noise, and low stray light of the instrument

◆ Large-screen dot-matrix LCD display, digital membrane key input, friendly interface and easy operation

◆ Long-life environment-friendly flange-type deuterium lamp, no need for optical debugging when changing the lamp

◆ The map and data are saved in real time, and can be kept after power failure, which can be printed and exported to PC

◆ Sturdy base plate and optical bracket, imported key components, durable

◆ With optional PC scanning software, online operation is more convenient, and the ability of data processing and storage is expanded
