Product details
Large screen scanning quasi dual beam UV visible spectrophotometer
Large screen, scanning type, dual beam spectrophotometer, user-friendly interface, easy operation, including all the testing functions of conventional spectrophotometers, high accuracy, low noise, meeting a wide range of application needs such as daily analysis and scientific research.
Instrument functions
◆ Luminescence measurement: transmittance T%, absorbance Abs, energy E
Quantitative testing: concentration content C (coefficient method, standard curve method)
◆ Wavelength scanning (spectral scanning): scanning range, interval, and speed can be set
Time scanning (kinetics): measure the change spectrum and calculate the reaction rate
◆ DNA/protein determination: ratio and concentration are directly displayed, and customizable methods are available
◆ Multi wavelength testing: simultaneously measuring results at multiple arbitrary wavelengths
Other functions: system application, graph data processing, report printing, etc
Instrument characteristics
The quasi dual beam proportional monitoring optical path can effectively suppress the drift of the circuit optical path and is suitable for long-term testing
◆ Automatic wavelength calibration, automatic dark current and blank correction, automatic switching of light source and filter
◆ Spacious sample room, capable of accommodating 5-100mm colorimetric dishes, supporting various accessory parts required for testing
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 thin-film key input, user-friendly interface, easy to operate
◆ Long life environmentally friendly flange seat deuterium lamp, no optical debugging required for lamp replacement
Real time saving of graphs and data, with the ability to maintain power off, printable, and exportable to PC
◆ Sturdy base plate and optical bracket, imported key components, durable and long-lasting
Optional PC scanning software makes online operation more convenient and expands data processing and storage capabilities
