The V-730 UV-visible/NIR spectrophotometer is designed to be simple to use with precise results, with 1nm spectral bandwidth for high resolution and a linear dynamic range to over 3AU across the entire spectrum.
Innovative features include IQ Accessory automatic recognition and IQ Start for push-button operation of routine measurements. The wide wavelength range from 190 to 1100nm offers versatile measurement for many different applications. Spectra Manager 2.5 Suite Spectroscopy Software the latest innovative, cross-platform spectroscopy software, or the iRM, a handheld controller with color LCD touch screen, both provide full system control and advanced data processing.
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. 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.
An extensive range of accessories is available for the V-750 spectrophotometer 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.
The V-760 UV-Visible spectrophotometer includes a double monochromator for exceptional resolution with extremely low stray light (0.00008 %) for more accurate measurement over the widest photometric range (up to 6AU). The V-760 provides excellent sensitivity for diffuse reflectance or transmittance of solid and liquid samples using an integrating sphere. For high resolution measurements, such as gas and vapor phase spectroscopy, the spectral bandwidth can be set as narrow as 0.1 nm. Extended photometric linearity up to 8 Abs enables measurement of highly absorbing samples and is also useful for measurements of optical material with transmission characteristics that approach 0 % T.
The V-770 UV-Visible/NIR spectrophotometer features a unique single monochromator design for maximum light throughput with excellent absorbance linearity. A PMT detector is used for the UV to visible region and a Peltier-cooled PbS detector for the NIR region.
The V-770 measures the wavelength range of 190 to 2700nm (option 3200nm). The single monochromator design offers a significantly higher energy throughput than a double-monochromated design resulting in a better S/N ratio over the entire spectral range, even with narrow spectral bandwidth. The gratings and detectors switch-over can be set to change automatically between 800-900nm .
V-770 can be equipped with Integrating spheres measure either the diffuse transmittance or reflectance of a liquid, solid or powder samples. Typically UV-Visible or UV-Visible/NIR spectrophotometers are used to measure the transmittance of a homogeneous, transparent liquid or solid sample. However, when the light is diffusely scattered by samples such as suspended liquid, opaque solid or powders only a small portion of the light reaches the detector. An integrating sphere captures most of the light from the sample offering a more representative measurement of the sample. All JASCO Integrating spheres include built in detectors for optimal sensitivity – PMT for UV-visible, InGaAs up to 1600nm and PbS up to 2500nm
The V-780 UV-visible/NIR spectrophotometer features a single monochromator with automatically exchanged gratings: 1200 lines/mm for the UV-Visible region and 600 lines/mm for the NIR region. A PMT detector is used for the UV-Visible region and a high sensitivity InGaAs detector in the NIR region. Both gratings and detectors are automatically exchanged within a user selectable range of 800 to 900nm.
The V-780 UV-visible/NIR spectrophotometer is used for spectroscopy in the wavelength range 190nm to 1600nm with enhanced sensitivity (compared to a PbS detector) in the NIR region using an InGaAs detector. The single monochromator design offers a higher energy throughput compared to a double monochromated instrument, resulting in a higher S/N ratio throughout the entire spectral range, even using narrow spectral bandwidths.
