Spectrophotometer LLG-uniSPEC 4

High-quality and cost-efficient UV/VIS spectrophotometer for pharmaceutical, biochemical, and clinical lab applications. Suitable for different measurement types such as kinetics, wavelength scans, quantitative analysis, multi-wavelength, and DNA/Protein analysis. LLG-uniSPEC 4 is ideal for complex measurements e.g. required for quality controls.

LLG-uniSPEC 4 features a small band width and a high wavelength accuracy. The device can store and save 200 calibration curves. A pre-adjusted lamp design allows a fast and easy lamp replacement. Both lamps can be individually turned on/off to extend the durability. The device can be used either as stand-alone unit or can be operated via a PC by using the supplied software.
