Jasco V-770 UV-vis-NIR Spectrophotometer

A unique optical design with a single monochromators and dual detectors for the wavelength range from 190 to 2700nm

A unique optical design with a single monochromators and dual detectors for the wavelength range from 190 to 2700nm (3200nm option).

The V-770 offers the unique benefit of single monochromator for higher optical throughput compared to double monochromated systems. This is especially usefulfor diffuse and specular reflectance measurements in the NIR where signal-to-noise can be a problem.

Jasco V-770 UV-vis-NIR Spectrophotometer

The V-770 can be used with most absorbance, transmittance or reflectance measurement in the UV-visible to NIR region, including liquids, solids and with options for for specular absolute and diffuse reflectance.

The V-770 uses a combination of wide range monochromator, PbS detector and anhydrous windows to cover the wavelength range to 3200nm.The high optical throughput of a single monochromator design provides excellent signal to noise when measuring transmission, diffuse and absolute reflectance to longer wavelengths.

  • Simplicity and Ease-of-Use

    Spectra Manager™ provide an intuitive interface allowing first time users to operate the instrument with ease.

  • High-Speed Scanning

    High-throughput optics and fast response detectors allow the V-770 to scan at speeds up to 4000 nm/min without wavelength tracking errors.(8000 nm/min in Pre-view mode).

  • Sampling Accessories

    A wide range of sampling accessories include: autosamplers & sippers, cell holders, flow cells, temperature controllers and software applications.

  • Instrument Validation and Regulatory Compliance

    The V-770 includes user-selectable validation to USP, EP and JP (or manually editable). With optional IQ/OQ.

Other V-770 features

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.

IQ Accessory
Automatic accessory recognition matches the measurement program to the attached sampling accessory.

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 Start
