Dual Beam UV-VIS 3100XE Spectrophotometer

Dual Beam UV-VIS 3100XE Spectrophotometer


1.Photometry measurement

Measure absorbance and transmission at any defined wavelength.

2.Multi – wavelength Measurement

Measure absorbance and transmission at multiple wavelength and analyze the results by built-in methods

3.Time scanning

Determine absorbance at any time interval and defined wavelength.


Determine absorbance at any time interval and defined wavelength. It can be used to monitor real time enzyme reaction and calculate enzyme activity according to the results. The reaction rates of samples can be calculated by setting the interval time.


By measuring reference samples and establish standard curve, to determine unknown samples. Support built-in and customized formulation to establish standard curve.

6.DNA/Protein Determination

According to the sample type, chose suitable method to determine DNA,RNA and Protein concentration.

7. wavelength Scanning

Determine full wave length absorbance and transmission at defined wave length interval, generate and analyze the graph by built-in methods.

8.Customized Methods

Users can adjust the calculation methods upon own requirement and use it in corresponding determining module.
