I.Overview
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
