Overview
The YOKE V729 Scanning Visible Spectrophotometer is a powerful analytical instrument that can easily perform photometric analysis, quantitative analysis, kinetic analysis, Light spectrum scanning, multi-wavelength measurement and DNA/protein analysis with simple parameter setting.
Features
1. Adopt a new ARM system with built-in Chinese and English dual operating systems, which can store and transfer data through the USB interface.
2. Powerful, the host can independently complete photometric measurement, quantitative measurement, Light spectrum scanning, kinetics, DNA/protein testing, multi-wavelength testing and data printing and other functions.
3. The instrument uses a 320 × 240 dot matrix high-brightness liquid crystal display to directly display the scanning map, with simple screen display.
4. Unique design Optical inspection system, high performance 1200/mm grating and imported receiver ensure that the instrument has excellent performance indicators.
5, socket neon lamp and tungsten lamp design, no Optical inspection debugging after changing the lamp.
6, 24-Bit High Speed, High Accuracy A/D conversion, high instrument accuracy, fast response speed.
7. The wide sample chamber can accommodate 5-100mm Colorimetric dishes of various sizes.
8. Can be directly connected to the printer to print maps and experimental data.
9. Scanning through YOKE software can be directly operated online.
10, the instrument can be selected swirl/spin type automatic eight sample holder, Reliability is good, the light spot is centered (compared to double row automatic eight frame), so that the instrument photometry accuracy is high.
Principle
The instrument works based on the principle of Spectrophotometric method, spectra-trophotometry. The composite light emitted by the light source is separated by a monochromator (high-performance grating) and becomes monochromatic light of a specific wavelength. When the monochromatic light passes through the sample solution, part of the light is absorbed. The transmitted light is received by the imported silicon photodiode Detector and converted into an electrical signal, which is then converted into a digital signal through a 24-bit high-speed, High Accuracy A/D converter, and finally processed by the ARM system. Absorbance, light transmitance and other measurement results or scan patterns are displayed directly on the LCD screen.
Applications
Photometric analysis, quantitative analysis, kinetic analysis, Light spectrum scanning, multi-wavelength measurement, DNA/protein analysis
Steps
1. Turn it on and warm up.
2. According to the analysis requirements, set the Measurement mode (such as photometry, quantification, scanning, etc.) and related parameters through the instrument interface.
3. Put the blank solution and the sample to be tested into a suitable Colorimetric dish and place them in the sample chamber.
4. Carry out blank correction.
5, start measurement, the instrument automatically reads and displays the data or map.
6. Data can be stored through the USB interface, or the results can be printed directly by connecting to a printer.
Notice
The instrument should be placed on a stable, vibration-free workbench.
• After starting the machine, it needs to be preheated for an appropriate time to ensure the stability of the light source.
• When using a Colorimetric dish, keep its transparent surface clean to avoid fingerprints or stains affecting the Measurement accuracy.
• When replacing neon or tungsten lamps, please use the specified socket lamp source. Optical inspection and debugging are not required after changing the lamp.
When connecting external devices (e.g. printers, computers), make sure the interfaces match and connect when the instrument is turned off.
• Regular instrument maintenance and calibrating to ensure the accuracy of measurement data.
