V-760 UV-Visible/NIR Spectrophotometer

xThe V-760 is a high resolution UV-visible double-beam spectrophotometer with double monochromator for exceptional stray light and absorbance linearity, variable spectral bandwidth and a photomultiplier tube (PMT) detector

System Description

The optical bench in the V-760 UV-visible spectrophotometer utilizes a double monochromator to provide exceptional resolution with extremely low stray light (0.00008%) to assure more precise measurement over the widest photometric range. The V-760 provides excellent sensitivity for diffuse reflectance or transmittance of solid and liquid samples using an integrating sphere. The spectral bandwidth can be set as narrow as 0.1 nm for high resolution measurements, such as gas and vapor phase spectroscopy. Extended photometric linearity up to 8 Abs enables measurement of highly absorbing samples and is also effective for measurements of optical material with transmission characteristics that approach 0 %T.

Operating Systems

Two user interfaces are available. The Spectra Manager™ II software, the latest version of JASCO's innovative cross-platform spectroscopy software, is now compatible with Windows 7 Pro (32- and 64-bit configurations) and the Windows 8.1 operating systems.

For simple and routine operation, the intelligent remote module (iRM) has been completely redesigned with a new look and feel, with a color LCD touch screen. Data can also be downloaded to a USB memory stick for portability or further PC data processing.

The V-700 Series has a growing list of software applications for both Spectra Manager II and for the iRM. If you have 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 of these 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.

System Features

IQ Accessory and IQ Start

The IQ Accessory function provides automated accessory recognition with identification of the accessory within the method. The spectral data files include the accessory information and serial number while designated instrument parameters can be configured and loaded for optimum sample measurements. IQ Start together with the Start Button is used to immediately start a sample method for immediate access when making routine measurements.

Excellent Optical Performance

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

Full Line of Sampling Accessories

A full complement 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 your desired instrument.

Options include a wide variety of liquid cell holders, micro and ultra-micro cell holders, flow cell units and accessories for solid samples. Advanced accessories, include 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.
