Accessories for Helios Spectrophotometers: Software Packages Software packages are available to complement the Helios Models. Vision 32 Standard and Rate software can be used with all Helios models.Vision 32 Standard includes Scan, Fixed, Quant and UV calc applications.Operates under Windows 95, Windows 98 or Windows NT, version 4.0 or higher.Vision 32 Rate runs kinetics tests, real time and post-run calculations of data and requires Vision 32 Standard for operation. Grafit provides a Windows-based data fitting package for enzyme characterization, ASDS is an automated sequence of development software and UV-Calc is used for local control systems. Sample Handling Calibration Accessories The Calibration Validation Carosel (8404A19) performs automatic unattended instrument performance checks on the Helios Alpha and Beta spectrophotometers. These checks include all critical UV-VIS spectrophotometer performance parameters essential for laboratories under any sort of regulatory control. The carousel fits in place of the cell programmer, screwing into place, to allow quick and easy operation. The calibration of the wavelength and visible absorbance filters is an ISO/IEC Guide 25 accredited process, providing a third party guarantee to the accuracy of the filter values.
