Jasco V-750 UV-vis Spectrophotometer

A high-resolution UV-Visible double-beam spectrophotometer with single monochromator

A high-resolution
UV-Visible double-beam spectrophotometer with single monochromator

The V-750 UV-Visible Spectrophotometer optical design uses precision double-beam optics with variable spectral bandwidth. A high sensitivity PMT detector provides accurate and reproducible measurements for low to high concentration samples.

Jasco V-750 UV-vis Spectrophotometer

By controlling the high voltage applied to the PMT, the dynode feedback offers a wider dynamic range than is generally found on uv-visible spectrophotometers. For high resolution measurements, such as gas and vapor phase spectroscopy, the spectral bandwidth can be set as narrow as 0.1 nm. Special low stray light slit settings which optimize the light image on the monochromator provide increased linearity to up to 5 absorbance units.
  • ● Double-beam spectrophotometer with single monochromator
  • ● PMT Detetcor
  • ● Wide wavelength range – 190 to 900 nm
  • ● Variable bandwidth down to 0.1 nm for high resolution measurement
  • ● High-speed scanning up to 8,000 nm/min
  • ● Linear up to 4 Abs

Operating Systems

Two user interfaces are available. Spectra Manager™ Suite the innovative cross-platform spectroscopy software, compatible with Windows 7 Pro (32- and 64-bit), Windows 8.1 and Windows 10 operating systems.

For simple operation, the intelligent remote module (iRM) has a new look and feel, with a color LCD touch screen. Data can be downloaded for portability or further PC data processing using Spectra Analysis.

The V-700 Series of UV-visible spectrophotometers has a growing list of software applications for both Spectra Manager™ and for the iRM. If you require an application which you don’t see listed, please let us know as we may already have it or we can prepare an application designed specifically for your requirements.

Both interfaces allow full system control and advanced data processing. Spectra Manager™ CFR is the 21 CFR part 11 compliant version of software and is available as an option.

  • IQ Accessory and IQ Start

    IQ Accessory provides automated accessory recognition with automatic loading of a user defined method. Spectral data files include the instrument and accessory information while designated instrument parameters can be configured and loaded for optimum sample measurements. IQ Start together with the Start Button is used to start a sample method for immediate access when making routine measurements.

  • Optical Performance

    The most recent advances in optical technology have been used to provide excellent instrument reliability and assure highly accurate results. High throughput optics combined with the latest in electronic design provide excellent sensitivity and stability for all sample measurements.

  • Sampling Accessories

    An extensive range of accessories is available for the V-700 Series of UV-Visible/NIR spectrophotometers for virtually any biological, material science or routine QA/QC measurement. Some accessories are common across the V-700 Series and others are instrument specific. Refer to the instrument brochure for accessories specific to this instrument.

    Options include a wide variety of liquid cell holders, micro and ultra-micro cell holders, flow cell holders and accessories for solid samples. Advanced accessories, including automated cell changers, sippers, integrating spheres, automated and manual absolute reflectance accessories and programmable temperature control systems are available for any of the V-700 instrument systems.

  • Instrument Validation and Regulatory Compliance

    The V-750 includes user-selectable validation to USP, EP and JP (or manually editable). With optional IQ/OQ.

Other V-750 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.

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
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.

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.
