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 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
