Overview Application Features Specification

UV-VIS Spectrophotometer UV2900 is Controlled by PC totally, and it can scan automatically with new optical system and circuit design. Spectral bandwidth 0.1-5.0 nm continuous adjustable and set.
 

- Photometric measurement: Use fixed wavelength to measure absorption, transmittance and concentration.
- Spectrum scan: Scan spectrum after software option.
- Multi-wavelength test: Up to ten test wavelengths.
- Dynamics measurement (time scanning).
- DNA/ Protein concentration measurement.
- Quantitative determination.


 

- Long-term Stability: High quality optical components ensure long-term stability.
- Low stray light: Advanced optical system, low-noise electric circuit system and high quality optical components ensure low stray light and the more accurate high concentration measurement.
- User friendly interface: wide screen shows data, graphics and curve more clearly.
- Light source easily replaced: on-site and no adjustment needed.
- Easily upgraded: Many optional accessories enhance the flexibility and the measurement range of the instrument.
