JASCO｜UV-Visible Spectrophotometer
Feature :
- 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.
- Compact Design: The V-730 is compact with dimensions of only 441 (W) x 468 (D) x 216 (H) mm.
- Simplicity and Ease-of-Use: Both Spectra Manager™ and the iRM provide an intuitive interface allowing first time users to operate the instrument with ease.
- High-Speed Scanning: High-throughput optics and fast response detectors allow the V-730 to scan at speeds up to 8000 nm/min without wavelength tracking errors.
- Sampling Accessories: A wide range of sampling accessories include: autosamplers & sippers, cell holders, flow cells, temperature controllers and software applications.
- Instrument Validation and Regulatory Compliance: The V-730 includes user-selectable validation to USP, EP and JP (or manually editable). With optional IQ/OQ instrument qualification.
- Double-beam spectrophotometer with single monochromator
- Silicon photodiode detectors
- Fixed bandpass 1.0 nm for high resolution measurement
- Dedicated V-730 bio for bio-physical analysis such as kinetics, thermal melting and protein/nucleic acid quant.
