Overview

The UV visible spectrophotometer is an affordable instrument that uses microcomputer processing technology, which is easy to operate and automatically adjusts 100% T and 0% T. It can directly establish standard curves and multi wavelength testing functions on the host. The values of "A" and "T%" are displayed twice, eliminating the hassle of resetting and earning you more valuable time. Z first developed a 480x272 color screen display, USB data export function, and support for PCL class USB printers to print A4 paper in the same industry. The fully sealed structure and all optical mirrors have SiO2 protective film, which comprehensively reduces the influence of external gases and environment on optical components. Extend the lifespan of your instrument.

Product Details

The UV visible spectrophotometer adopts microcomputer processing technology and optical system at a reasonable price, with easy operation and automatic adjustment of 100% T and 0% T. It can directly establish standard curves, multi wavelength testing, spectral scanning, and biological methods on the host. The dual beam UV visible spectrophotometer is the first in the industry to develop a 480x272 color screen display, USB data export function, and support PCL type USB printers for printing A4 paper. The UV visible spectrophotometer is affordable with a fully sealed structure and all optical mirrors have SiO2 protective film, which comprehensively reduces the impact of external gases and environment on optical components and extends the service life of your instrument. The imported environmentally friendly deuterium lamp system of the dual beam UV visible spectrophotometer can effectively reduce your inhalation of ozone, making it more environmentally friendly and healthier.

Price of UV visible spectrophotometer

1. Photometric measurement

Measure the absorbance, transmittance, and energy of the sample at a fixed wavelength

2. Quantitative measurement

Two fitting methods: first-order and first-order zero crossing

Establishing standard curves using three methods: coefficient method, standard sample input, and standard sample input

Establish A=K1 * C K0, which can search for raw data, graph curves, and set parameters. Save 240 sets of curves, each set of curves can test 240 pieces of data

3. Multi wavelength

Zui can test the transmittance and absorbance of samples at 8 different wavelengths

4. Dynamics

Measure the absorbance or transmittance of the test sample at a fixed wavelength point over a period of timeVariation spectrum, which can calculate the sample reaction rate △A/tScanning time.The sampling interval, delay time, and wavelength point can be set according to actual needs

5. Spectrum

Set the scanning interval within the range of 190-1100nm according to the experimental requirements. Measure the sample

The maximum absorption peak can be used for data processing such as differentiation and mathematical operations on the spectrum

6. Biology

6 methods: DNA/protein quantification, UV method, Lowry method, BCA method, CBB method Biuret
