JASCO｜UV-Visible/NIR Spectrophotometer║All Series
Feature :
- Compact Design: The compact optical design of the V-700 Series of UV-visible spectrophotometers significantly reduces the requirement for bench space in the modern laboratory.
- Wide Wavelength Range: High energy throughput provides excellent signal-to-noise ratio for the entire UV-visible to NIR spectral range, with detectors selected for the highest sensitivity and dynamic range.
- Excellent Optical Performance: Sophisticated electronic and optical design reduces stray light for highly accurate measurements over a wide photometric range.
- High Speed Scanning: High throughput optics and fast detectors provide high-speed scanning without wavelength tracking errors.
- Dark Correction: Stray light reduction features enable highly-accurate measurements of high-absorbance samples.
- Monochromator Step Scanning: Step scan function provides reliable peak assignment of samples with sharp or narrow absorption peaks.
- User-Friendly: Spectra Manager™ Suite for Windows (with optional 21 CFR part 11 compliance) and iRM hand-held controller for comprehensive control, acquisition, and data processing.
- IQ Accessory: Automatic accessory recognition matches the measurement program to the attached sampling accessory.
- IQ Start: For routine operation, a measurement method can be activated with a simple push of the ‘Start Button’, great for routine operation or speeding up measurement for multiple users.
- Accessories: A comprehensive selection of over 50 sampling accessories for gas, liquid, and solid samples are available for many dedicated sampling applications.
- Regulatory Compliance: For GxP compliant laboratories, instrument validation protocols to USP, EP, and JP are included as standard. IQ/OQ support is also available.
