Helios Spectrophotometers’ superior optical system provides stability, precision and linearity. All units feature angled casing, sealed keypad to protect from spills, optional printer, plug-and-play self-aligning lamps, large LCD, VGA graphics, full-range scan displayed on-screen with peak pick-and-track facilities, choice of total control or PC-driven software, built-in methods storage, cell volume handling to 5 µL and 100% sealed optics to protect from dust and vapors.
Gamma/Delta
Bioscience-ready Helios Gamma and Delta Spectrophotometers can be read in either the visible (Delta) or UV-Visible (Gamma) ranges. Both models are single beam, basic-scanning spectrophotometers with peak picking ability. Feature up to 20 wavelengths and 30 methods storage capacity, password protection, Quartz-coated optics, RS-232C interface, autozero function and the ability to hold six ratio methods and 4 calibration curves in memory. Measurement modes include timed measurement intervals, Conc., Conc. factor ratio, corrected ratio, nucleic acid ratio and active display of Absorbance/% Transmission after initialization. New model is compatible with Vision 32 PC software for extensive data manipulation. Available with seven-position cell changer (carousel).
Alpha/Beta
The Helios Alpha and Beta Spectrophotometers measure in the UV-Visible range. The Alpha is a double beam, scanning UV-Vis, while the Beta is a single-beam scanning UV-Vis. Both include all the features of the Gamma and Delta models with additional functions including an integrated 1.44MB, 3.5” floppy disk drive, unlimited storage of methods, accessory methods and results, standard seven position, thermostatable cell changer and extended programming capabilities. Operation is completely menu-driven.
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.
