The new optical path design and sensitive photomultiplier tube receiver can be widely used in scientific research and production in various fields such as organic chemistry, biochemistry, pharmaceutical analysis, food inspection, medicine and health, environmental protection, life sciences, etc.
UV VIS Spectrophotometer Features:
7-inch 1024×768 Omron buttons and large-screen display directly display various scanning curves and charts, allowing users to complete all measurement needs without the help of a computer.
Supports U disk storage, which is convenient for users to use. User-measured data can be directly exported to U disk. It supports excel, txt format, and picture format. It can output four formats: *.csv, *.qua. *.tet, *.bmp.
Data output: RS-232C serial port (printing), USB drive (online), USB HOST (connected to U disk), standard 32GB memory.
The first in the industry to use the advanced 32-bit Cortex_M3 processor with a main frequency of 120M. The instrument can store 5,000 test data or 500 working curves internally.
Suspension optical system design, strengthened thickened aluminum base plate design, eliminates the impact of vibration or deformation on the optical system; double-layer design, completely separates each circuit part of the optical path.
The instrument uses a photoelectric signal detection device to make the signal-to-noise ratio of the instrument lower and the instrument more stable.

What are the unique advantages of using a flash xenon lamp as the light source?
The flash xenon lamp is a revolutionary light source for high-precision spectrometers, with 3 core advantages:
1. Ultra-long lifespan and zero maintenance cost.
2. Ready to use immediately, no preheating required.
3. High energy across the entire wavelength range, ensuring stability in the detection of complex samples.
What limitations can be overcome by combining a pulsed xenon lamp with a photomultiplier tube (PMT)?
Golden combination of two high-end hardware components perfectly solves 3 limitations in laboratory testing:
1. Protection of photosensitizing samples.
2. Direct measurement of high-concentration/turbid samples, outputting accurate spectra.
3. High efficiency, low power consumption, low carbon footprint, and extended overall lifespan.
