2800D series spectrophotometer are advanced double beam optical system. Double beam optical structure can inhibit the drift, Suitable for long time test.The 2800D series spectrophotometer has advanced functions such as quantitative measurement, wavelength scanning, time scanning, multi wavelength testing, DNA protein testing, etc. It has the characteristics of high precision, high resolution, low noise, and low stray light, and is particularly suitable for fields such as scientific research, pharmaceutical inspection, life sciences, environmental monitoring, metallurgy and chemical engineering.
Features
◆ Dual beam proportional monitoring optical path, low drift and high stability, suitable for long-term testing
◆ Push pull sample cover design, can be opened and closed with both hands, easy to operate
◆ Spacious sample compartment, capable of accommodating 5-100mm cuvettes, supporting various accessory
parts required for testing
◆ High quality optical and electronic components ensure high precision and low stray light of the instrument
◆ Large screen dot matrix LCD, clear display of graph data, user-friendly interface, easy operation
◆ Smaller spectral bandwidth, higher resolution, fully meets pharmacopoeia requirements, and has a wider range
of applications
◆ 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
◆ Standard PC scanning software, more convenient online operation, and expanded data processing and storage
capabilities
Function:
◆ 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
