Helios Zeta et Helios Omega

Cost-effective performance for routine and research analysis
The Thermo Scientific Helios™ Zeta and Helios Omega are easy-touse, reliable UV-Visible spectrophotometers designed for research, routine quality control, and teaching needs. The built-in, Local Control software offers unique solutions for a wide range of laboratory requirements – from fixed wavelength measurements and concentration determinations to wavelength scanning and multicomponent analysis.



For over 60 years, customers in worldrenowned research institutions, industrial laboratories, and teaching institutions have relied on Thermo Scientific UV-Visible spectrophotometers. The Helios Zeta and Helios Omega continue our tradition of providing high-quality spectrophotometers meeting the demanding needs of the routine and research laboratory. A wide range of accessories for your liquid and solid sampling requirements are available for use with the Helios instruments.

Quality and Performance
The Helios design uses a minimum number of optical components and provides excellent light throughput and affordable performance– all in a compact footprint. The dual-source tungsten and deuterium lamp system offers maximum performance over the entire wavelength range. The double-beam configuration of the Helios Zeta
provides excellent stability with the flexibility to measure both sample and reference samples simultaneously. A variety of sample and reference beam cell holder accessories makes the Helios Zeta a clear choice for demanding samples. The single-beam Helios Omega, with its wide selection of sample cell holders, provides a cost-effective solution.

Extensive Software Choices
 For maximum flexibility, the Helios spectrophotometers can be controlled from either the intuitive VISIONlite™ software suite or the more advanced VISIONpro™ interface. In regulated environments where 21 CFR Part 11 compliance is a requirement, VISIONlite SE or VISIONsecurity™ software provide extensive tools for data security, electronic signatures, and audit trails.

Increase Laboratory Productivity without Compromising Performance

Up and Running in Minutes with Intuitive Design
The intuitive, built-in keypad and graphically displayed SoftKeys ensure that methods can be quickly setup and executed. Traditional sample measurements such as fixed wavelength and concentration are only a few keystrokes away. The unique SmartStart™ feature puts your most frequently used methods on the first screen each time the instrument is turned on. SmartStart makes training users simple by providing easy access to the laboratory tests you use every day.
More Bench Space
 The compact design saves valuable bench space and leaves more room for additional laboratory equipment. The built-in USB interface provides easy connection to external USB compatible printers.

USB Connectivity
The USB interface, in conjunction with memory devices, gives you unlimited storage of data and methods. Easily transfer your data and methods onto memory devices for archiving. Communication connectivity for PC-controlled applications is provided using an optional USB interface cable.



Helios Zeta and Omega spectrophotometers provide excellent versatility for routine and research laboratories. On-screen data manipulations for wavelength scanning, up to 20 standards for calibration curves, fixed multiwavelength analysis, kinetics, and multicomponent are among the standard software applications.



Maximum ease-of-use with the integrated active display showing instant readouts of absorbance, % transmittance, or concentration.

Designed to Last

  • Precision, die-cast aluminum chassis provides robustness and stability
  • Quartz-overcoated, sealed optics maintain performance throughout the instrument’s lifetime
  • Minimal moving parts improve reliability, reduce maintenance, and cost of ownership
  • Sealed and chemically-resistant keypad withstands the harsh, multi-user laboratory environment

    Increase your lab’s productivity by combining the Helios spectrophotometers and CETAC 100/200/500 series autosamplers. The VISIONlite auto SE software provides 21 CFR Part 11 compliance for the regulated laboratory.

Designed for Productivity

  • Large sample compartment provides easy access to a wide range of sample handling accessories
  • Easy access to built-in application software methods
  • Built-in data and methods storage via USB memory devices
  • Integrated and automated sipper delivery systems
  • Optional CETAC® autosamplers for maximum liquid handling automation
  • Wide selection of dedicated, computercontrolled application packages for routine operation, color analysis, enzymatic food analysis, materials characterizations, and more

Additional Flexibility with Application Software

A range of software application programs is available for the Helios Zeta and Omega UV-Visible spectrophotometers.

  • VISIONpro is a full-featured and flexible software interface designed for generalpurpose, research laboratories. VISIONlife™ adds additional flexibility for monitoring single and multicell kinetics.
  • Designed for multi-user laboratories, the VISIONlite series consists of a singlewindow format providing applications for wavelength scanning, fixed multi-wavelength analysis, quantitative analysis, and kinetics.
  • VISIONsecurity and VISIONlite SE are available for laboratories requiring user authentication, audit trails, electronic records, and signatures for 21 CFR Part 11 compliance.
  • EnzLab, an analyzer software application for enzymatic food analysis, is available for food and beverage applications • Industrial liquid color and transmission color measurements can be performed using the VISIONlite ColorCalc software.

  • Luminous transmittance of optical materials is supported in VISIONlite MaterialsCalc software. Each of these application packages completely controls the Helios Zeta and Omega spectrophotometers and appropriate accessories.

VISIONsecurity not only has all of the acquisition, analysis, and reporting capabilities found in the VISIONpro software, but also has the tools necessary to control individual or group access to the instrument, data, and records. Windows® operating system integration allows VISIONsecurity activity to be monitored, even when 		VISIONsecurity is not running. Windows integration streamlines user entry and password maintenance, captures and sequesters event audit trails and electronic signatures, and prevents use when a network connection is lost or while the operator is away.

With continually changing requirements to keep your Helios spectrophotometer up to regulatory standards, no supplier in the industry can provide a more comprehensive selection of calibration and verification tools.
