Double Beam UV-Visible Spectrophotometer


A high resolution UV-Visible spectrophotometer with double-beam, single monochromator, variable spectral bandwidth and a photomultiplier tube (PMT) detector.

V-750 Double Beam UV-Visible Spectrophotometer

V-750 UV-Visible/NIR SpectrophotometerThe 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. 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.

With a comprehensive range of sampling accessories, the V-750 UV-Visible spectrophotometer is well suited for the measurement of solid and liquid samples in the UV and visible regions, with temperature control for biological samples and a number of transmittance and reflectance accessories for materials analysis.

Operating Systems

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

For simple operation, the intelligent remote module (iRM) has a new look and feel, with a color LCD touchscreen. 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 the iRM. If you require an application that 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 the software and is available as an option.

System Features

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.
