UV/Visible Spectrophotometer

The Lightwave II diode array UV/Visible spectrophotometer is the perfect combination of ease of use with flexibility, incorporating Gifford Optics with no moving parts and a Xenon source for high energy performance with longer lamp lifetime.

The instrument includes a large wide view display and in-built software providing flash scan, fixed wavelength measurements, kinetics and concentration with comprehensive graphics capability plus the ability to store up to 90 methods. On peak confirmation is also a feature of the flexible software. Concentration may be measured using either a factor, singlepoint calibration, multi-standard curves or alternatively there is a multi-wavelength mode where equations using absorbance values may be used for ratio calculations. Samples may be measured in 10, 20 or 40 mm pathlength cells (glass, quartz or disposable) and all results may be printed to an optional integrated high quality printer for permanent record. Alternatively the instrument may be linked to a PC via a USB connection or the optional wireless Bluetooth accessory for data storage or printing. The Lightwave II has been designed to meet the needs of customers in most laboratory situations and is compact, lightweight, convenient and excellent value for money compared to conventional systems. With its elegant new user interface, Gifford Optics and Bluetooth connectivity, the Lightwave II is an obvious choice in a multi-function environment. The Lightwave II+ is a higher resolution 3 nm bandwidth version.
