JASCO V-780 UV-Vis Spectrophotometer

The JASCO V-780 UV-Visible-Near Infrared (UV-Vis/NIR) spectrophotometer is a unique optical design incorporating a dual-grating, dual-detector design to fully cover the wavelength range from 190 to 1600 nm with enhanced sensitivity in the NIR region. It features a monochromator with automatically exchanged dual gratings: 1200 lines/mm for the UV/VIS region; 600 lines/mm for the NIR region. A PMT detector is provided for the UV-visible region and a high sensitivity InGaAs photodiode detector is employed for the NIR region for exceptional sensitivity.

Simplicity and Ease-of-Use

The JASCO V-780 UV VIS spectrophotometer is designed to allow even first time users to collect data with confidence. The IQ Accessory function provides automated accessory recognition while the Start Button is used to immediately start a sample method for immediate access when making routine measurements.

PC control with Spectra ManagerTM II software

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

Standard Applications include:

  • Wavelength scanning 190 to 1600nm
  • Time course measurement
  • Fixed wavelength measurement
  • Quantitative measurement
  • Extensive measurement features and advanced data processing

Excellent optical performance

Double Beam Optics
Scanning UV Vis spectrophotometer enables measurement against a reference sample through its double beam optics. Low stray light and Dark Correction feature enables highly precise measurements over a wide photometric range.

Single Monochromator, High Efficiency InGaAs Detector
The single monochromator design offers a higher energy throughput resulting in a better S/N ratio over the entire spectral range, even with narrow bandwidth settings. A PMT detector is provided for the UV-visible region and a Peltier-cooled InGaAs detector is employed for the NIR region. The InGaAs detector offers significant S/N enhancement over the PbS detector (see V-770).

Variable Bandpass, Step Scanning 
Step Scanning provides reliable peak assignment of samples with sharp or narrow absorption peaks.

High-Speed Scanning
High-throughput optics and fast response detectors allow the JASCO V-780 UV-Vis spectrophotometer to scan at speeds up to 8000 nm/min without wavelength tracking errors.

Compact Design
The optical bench of the JASCO V-780 UV-Vis spectrophotometer is extremely compact saving laboratory space.

'Start Button'
Single button push for immediate start of routine measurements.

Built in validation routine to verify instrument performance and is compliant with GMP/GLP and USP regulations. CFR – 21 compliant version of Spectra manager software is optional

Range of 50 Sampling Accessories with Automatic accessory recognition.
Options include cell holders, flow cells, temperature controllers and specific application software packages.  See the Full range of Accessories.
