EIKOH V-700 Series UV-Vis-NIR Spectrophotometer
Made in Japan
Manufacturer: Eikoh Co., Ltd.
Model: V-700 Series: V-730, V-750, V-760, V-770, V-780
The V-700 series UV-Vis-NIR spectrophotometers have been launched as the successor to the highly acclaimed V-600 series. With a diverse lineup of models, we provide users with the highest performance for their measurements and a completely different experience. The V-730 is suitable for routine work, the V-750 and V-760 are high-sensitivity UV-Vis models, and the V-770 and V-780 can measure up to the near-infrared region.
Achieves excellent linearity over a wide wavelength range
We have improved the proven optical system. A wide dynamic range has been achieved by adopting an ultra-high resolution A/D converter and optimizing the optical system and signal processing.
Supports reliable measurements
Supports Validation
The system offers a validation program. Choosing a standard like JP or USP instantly determines the necessary test items. After starting, simply follow the dialog box instructions to ensure a smooth testing process.
* A separate jig is required.
Daily Inspection Program
A daily program checks the instrument’s condition, included as standard. Each day begins with spectral measurements on filters and other items that remain stable over time. The results are automatically saved, and past measurements can be reviewed chronologically, maintaining data reliability.
* Use the same one every time.
Equipment Diagnostic Function
Every time the device starts, it checks the status of the light source and wavelength drive.
Control the device via PC or dedicated module
As a tool to control the spectrophotometer, you can choose between a PC or the small module iRM dedicated to device operation.
IQ Accessories (Automatic Accessory Recognition System) & IQ Start
The V-700 series is equipped with IQ accessories, which allow accessories to be automatically recognized by the software and accessory names, serial numbers, etc. automatically recorded in measurement data.
