产品介绍
Function
Photometric measurement: permeance T%, absorbance Abs, energy E
Quantitative test: concentration content C (coefficient method, standard curve method)
Wa velength scanning (spectral scanning): the scanning range, interval and speed can be set.
Time scanning (dynamics):Measure the spectrum changing and calculate the reaction rate.
DNA/ protein determination: the ratio and concentration are clear and can be customized.
Multi wa velength measurement: simultaneous measurements of multiple wa velengths .
Other function:system application ,data processing, report printing, etc.
Characteristic
The dual beam light path, low drift and high stability can compensate for reference changes, suitable for long time testing.
Push and pull sample cover design, both hands are busy can also open and close the cover, easy to operate
The large sample room accommodates the 5-100mm cuvette and supports necessary accessories for various tests.
Optics and electronic components with high quality to ensure high accuracy and low stray light.
Dot matrix liquid crystal display, touch film button, friendly interface and easy operation.
Smaller spectral bandwidth, higher resolution, fully meet the requirements of Pharmacopoeia and the scope of application.
Long life environmental protection, flange seat type of deuterium lamp, changing lamp needn’t optical modulation.
The atlas and data are stored in real time, and can be maintained, printed and exported to PC when power off.
Strong baseplate and optical holder support, the imported critical components are durable.
Optional PC quantitative a nalysis software, online operation is more convenient, expanding the data processing and storage capabilities.
