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.
- Excellent Optical Performance: High throughput optics combined with the latest electronic design provide excellent sensitivity and stability for a wide range of sample measurements.
- Sampling Accessories: An extensive range of accessories is available for the V-760 UV-Visible/NIR spectrophotometers for virtually any biological, material science or routine QA/QC measurement.
- 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-760.
- Instrument Validation and Regulatory Compliance: The V-760 includes user-selectable validation to USP, EP and JP (or manually editable). With optional IQ/OQ.
- Double-beam spectrophotometer with double monochromator
- Photomultiplier tube detectors
- Photometric range up to 8 AU
- low stray light 0.00008 %
