Newly Upgraded

Truly realizing intelligent one click sending


Instrument and equipment details

Features: Automatic light seeking and positioning!

Truly realizing users' freedom to change lights! No need to disassemble the instrument casing Deuterium lamps and tungsten lamps are all externally replaceable, so you no longer have to worry about the light not hitting the entrance slit after changing the lamp The problem of unstable data cannot be solved as long as the light is installed

Manual intervention is required to adjust the dimming path, and the instrument will automatically find a better position, more accurate and stable!

The interface of the instrument host is as follows

Time Scan——Dynamics measurement, also known as time measurement, refers to the process where users set wavelength points based on their own samples and scan the sample solution within a certain scanning time range at regular intervals
Measure absorbance or transmittance at scanning intervals, or convert absorbance to concentration by inputting concentration factors.
Can perform time scanning to set single wavelength absorbance or transmittance, and establish absorbance (or transmittance) - time curve




Basic measurement——Input the wavelength to test the sample content value at that wavelength, and input the sample content to test unknown samples





Spectral scanning——The sample needs to draw the maximum absorption peak within a certain wavelength range,




Automatically provide peaks and valleys of unknown samples(Qualitative analysis)





Multi wavelength measurement——Refers to the need to measure absorbance/transmittance/concentration of a sample at multiple wavelengths





Quantitative measurement
For quantitative analysis of samples, multiple standard samples (two or more) can be used to establish absorbance concentration curves at different wavelengths, and the unknown sample concentration can be obtained from these curves.



Quantitative measurement-By inputting known X and B values, the content of unknown samples can be measured





DNA protein measurement

Measurement Plan 1: 260nm 280nm

Measurement Scheme 2: 260nm 230nm

The automatic measurement of DNA/protein mainly involves measuring the absorbance at the points of 260nm/280nm/230nm/320nm, and obtaining the concentration of DNA and protein according to the calculation formula.
