Description

USP-1901A Double beam UV-visible spectrophotometer

Product introduction

USP-1901A Double beam UV-visible spectrophotometer is used for basic absorbance measurement, quantitative and qualitative analysis, DNA and kinetic analysis, etc.


Instrument features

Adopt low stray light and high-resolution optical path structure monochromator, which has good stability, reproducibility and accurate measurement readings.

The variable slits can be set to 0.1/0.2/0.5/2/4/5nm to meet the requirements of different analytical test items for monochromatic bandwidth.

Adopt the latest microprocessor technology, with control functions such as automatic setting of 0%T and 100%T, various methods concentration calculation and data processing functions, and also has special functions to prevent user operation errors, so you can use it without worries.


Instrument Interfaces

Time scan - kinetic measurement is also called time measurement. The user can measure the absorbance or transmittance of the sample solution at intervals (scanning intervals) within a certain scanning time range according to the sample set wavelength point, and can also convert the absorbance into concentration by inputting the concentration factor.

You can set a single wavelength absorbance or transmittance time scan to establish an absorbance (or transmittance)-time curve.

190 - 1100nm Double Beam UV Visible Spectrophotometer For Basic Absorbance Measurement

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

190 - 1100nm Double Beam UV Visible Spectrophotometer For Basic Absorbance Measurement

Spectral scanning - the sample needs to draw an absorption peak within a certain wavelength, and automatically give the peaks and troughs of unknown samples (qualitative analysis).

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

190 - 1100nm Double Beam UV Visible Spectrophotometer For Basic Absorbance Measurement

Quantitative measurement - To conduct quantitative analysis of samples, multiple standard samples (more than two) can be used to establish a wavelength absorbance-concentration curve, and the concentration of unknown samples can be obtained from this curve.

Enter the known X, B values to measure the content of unknown samples.
