Function Introduction:

Basic mode:Absorption value, transmission and concentration measurement, other units can also be selected: ug/ml, mg/L, g/L, ppm,%,

I.U., mM/L, M/L。

Quantitative:New or stored calibration curves can be used to measure unknown concentrations, and up to 10 standard solutions can be used to establish calibration program curves.methodincluding:

Linear, quadratic fitting, cubic fitting, and other calibration methods include single wavelength method, ISO absorption method (dual wavelength method), and three-point method.

Wavelength scanning:You can choose to scan at different rates and wavelength intervals within any wavelength range.

Scanning interval:0.1/0.2/0.5/1/2/5nm。

Scanning rate:100 to 1000nm, high/medium/low speed.

Dynamics measurement:Measure the absorption rate over time for up to 12 hours, and display the results in real-time on the screen with intervals of 0.5/1/2/5/10/30 seconds

And 1 minute. Subsequent processing includes callbacks, curve tracking, selecting curve segments for velocity calculation, etc. DNA/protein measurement: including concentration measurement and purity measurement

30 methods including temperature measurement and ratio at different wavelengths. Including absorption ratios of 260/280nm and 260/230nm.

Multi wavelength measurement:Up to 10 wavelengths can be input for measurement under multiple wavelengths of the same product.

GLP reportUsed for GLP certified laboratories.

Data storage200 points, including absorbance value and ratio, sample size, dilution, date and time, machine self calibration upon startup, standard at 656.1nm, wave

Long precision can be detected using the built-in WL Validity program, while absorption precision can be detected using the built-in Accu Validity program.
