1. Product introduction

1. The V729 large-screen scanning visible spectrophotometer adopts the latest arm system, built-in Chinese and English dual operating systems, and can store and transfer data through the USB interface.

2. Powerful functions, the host can independently complete the functions of photometric measurement, quantitative measurement, spectral scanning, kinetics, DNA/protein testing, multi-wavelength testing and data printing.

3. The instrument adopts 320`240 dot matrix high-brightness 6 liquid crystal display, which directly displays the scanning map, and the screen interface is simple and convenient to use.

4. Special optical system design, high-performance 1200/mm grating and imported receiver ensure that the instrument has excellent performance indicators.

5. Socket type neon lamp and tungsten lamp design, free optical debugging after lamp replacement.

6. 24-bit high-speed, high-precision A/D conversion, the instrument has high precision and fast response.

7. The large sample room can accommodate 5-100mm cuvettes of various specifications.

8. It can be directly connected to a printer to print maps and experimental data.

9. Direct online operation through scanning software.

The V729 large-screen scanning visible spectrophotometer can be equipped with a disc rotating automatic eight-connected sample rack, which has good reliability and a center light spot (compared to the double-row automatic eight-connected rack), so the instrument has high photometric accuracy.
