The V-730 is a general-purpose double-beam spectrophotometer with a compact space-saving design. Its excellent spectroscopic performance is suitable for routine QC, teaching, and research applications.
User friendly features include IQ Accessory for automatic accessory recognition and IQ Start for quick start of routine measurements. The V-730 UV-visible/NIR spectrophotometer is operated by Spectra Manager II Suite, 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. Spectra Manager CFR (for 21 CFR part 11 compliance) is available as an option.
Both Spectra Manager™ and the iRM provide an intuitive interface allowing first time users to operate the instrument with ease.
The V-730 is compact with dimensions of only 441 (W) x 468 (D) x 216 (H) mm.
High-throughput optics and fast response detectors allow the V-730 to scan at speeds up to 8000 nm/min without wavelength tracking errors.
A wide range of sampling accessories include: autosamplers and sippers, cell holders, flow cells, temperature controllers and software applications.
The V-730 includes user-selectable validation to USP, EP and JP (or manually editable). With optional IQ/OQ.
