Key Differentiators:

• UV-9000 Advantage: This series features a Double Beam optical system, which significantly improves stability (0.0005A/h) and reduces stray light compared to the 6000 series.

• Suffix Meanings:

  • Standard (No Suffix): Fixed 1.8nm bandwidth.

  • A Series: Fixed 1nm bandwidth for higher resolution.

  • S Series: Adjustable bandwidth (0.5/1/2/4nm), offering maximum flexibility for diverse research requirements.

• Precision: Wavelength accuracy and photometric precision improve as you move from the 6000 to the 9000 series.

  
  

  
  

  Technical Comparison: X Series Spectrophotometers

Core Upgrades of the X Series:

• X8 Series Performance: Unlike the X6, the entire X8 line uses a Double Beam optical system and a larger 10-inch touch screen, providing superior stability and a better user interface.

• Precision and Bandwidth:

  • X8A provides a narrower 1nm bandwidth for higher resolution.

  • X8S offers the most flexibility with four switchable bandwidths (0.5/1/2/4nm), making it ideal for specialized research applications.

• Connectivity: Both series support modern data handling through USB and optional Bluetooth, allowing for easier data export and laboratory integration.

FAQs

1. What is the main difference between Single Beam and Double Beam systems?

Single beam models (UV-6000, UV-6100, X6) utilize one light path, while Double Beam models (UV-9000, X8 series) split the light into two paths. This allows for real-time compensation of light source fluctuations, resulting in superior stability and higher accuracy.

2. What do the suffixes "A" and "S" represent in your model numbers?

The suffixes indicate the bandwidth configuration:

• Standard (No Suffix): Fixed 1.8nm bandwidth.

• A Series: Fixed 1nm bandwidth for higher resolution.

• S Series: Adjustable bandwidth (0.5/1/2/4nm) for versatile research requirements.

3. How does the optical base plate affect instrument performance?

The UV-9000 and X series feature a 16mm-thick rigid die-cast aluminum base (8mm for UV-6000). This heavy-duty structure ensures that all optical components remain perfectly aligned, promising long-term stability and resistance to external vibrations.

4. What is the wavelength range for these spectrophotometers?

All models in the UV and X series cover a broad wavelength range of 190nm to 1100nm, spanning the entire Ultraviolet and Visible light spectrum.

5. What type of light sources are used in these instruments?

Every model is equipped with a high-quality Tungsten Lamp (W Lamp) for visible light and a Deuterium Lamp (D2 Lamp) for UV light to ensure consistent performance across the full spectrum.

6. What are the advantages of the X Series compared to the UV Series?

The X Series is our "Smart" line, featuring high-definition touch screens (7-inch or 10-inch), an automatic 8-position cell holder, and built-in stand-alone operating systems for a more intuitive user experience.

7. Can I use the X Series without a computer?

Yes. The X Series features a powerful stand-alone system with a large touch screen, allowing you to perform complex functions directly on the instrument. PC software is available as an optional add-on for advanced data analysis.

8. Is wireless data transfer supported?

The X series supports fast data output via USB port and offers an optional Bluetooth module for wireless connectivity, making it easy to integrate into modern lab environments.

9. How stable are these instruments during long tests?

The UV-9000 series offers the highest stability at ≤0.0005A/h, while the X series and UV-6000 series maintain high performance at ≤0.001A/h.

10. What is the stray light specification for the high-end models?

The UV-9000 series leads with stray light levels at ≤0.03%T, ensuring high photometric linear accuracy even when testing samples with high absorbance.

11. Do the instruments support automatic calibration?

Yes, models like the UV-9000 include a one-button automatic calibration system to ensure the instrument is always operating at peak precision with minimal downtime.

12. Is PC software included with the spectrophotometers?

Multi-functional PC software is available as an option for all series, providing advanced tools for quantitative analysis, kinetics, and spectrum scanning.

13. Are there different sample holder options?

Yes, the X series features a large sample chamber and comes standard with an automatic 8-position cell holder, with various other accessories available to suit different sample types.

14. What are the power requirements for international use?

All models are designed for global compatibility, supporting AC 110/220V at 50/60Hz.

15. Can I request trial samples before placing a bulk order?
