Lightwave 3 and 3+ Spectrophotometer
Lightwave 3 and 3+ Spectrophotometer
The Lightwave 3 and 3+ diode array spectrophotometers offer all the benefits associated with the established Lightwave range. Predefined methods for rapid scanning, kinetics, and concentration capabilities, a variable pathlength cell holder up to 40 mm and their compatibility with disposable low volume UV cuvettes have made them a common sight among educational and industrial laboratories alike.
Powerful and flexible
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, single point 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 40mm pathlength cells (glass, quartz or disposable).
Flexible data export options
All instruments have a USB port to download result data to a flash drive in a CSV file format. Alternatively, results may be printed to an optional integrated graphical printer for a permanent record or exported via a USB cable connection to a suitable PC running Print Via Computer (PVC) software for advanced reporting and data storage or the optional wireless accessory.
