EnzLab Spectrometer System

The EnzLab Spectrometer System is a comprehensive system for spectrometric food analysis including enzymatic analysis and other photometric tasks. The system includes the Thermo Scientific Helios delta Vis-spectrometer with a thermostatable 7-cell changer. The instrument features an affordable price, small footprint (45 x 40 cm), an exchangeable sample turret and good general optical performance. The wavelength range is 325-100 nm at a spectral bandpass of 2 nm. Thus the instrument covers all wavelengths settings necessary for enzymatic food analysis and assures accurate results even for highly absorbing samples (up to 3 A).

The comprised EnzLab software assures the fast routine determinations of important food constituents with up to 7 samples in parallel.

The system comes with the Thermo Scientific
VISIONlite 32-Bit Windows software, which includes modules for general spectrum scanning, enzyme activity determinations and photometric quantitative measurements.

The system requires a standard PC with an RS232 interface and a 32-Bit Windows operating system. For fast access, the spectrometer can be operated also directly without PC.
