Specific use cases in various industries

The Vista® has been used successfully for years in various industries, including the following use cases:

Crystalline or powdery samples

Peltier heating element for color measurement of crystalline or powdery samples that must first be melted in a controlled manner, e.g. fats or waxes.


Oil, resin, solutions, syrup

Color measurement of oils, resins, solutions and syrups can be carried out quickly with the HunterLab Vista, with different sized cuvettes made of glass or plastic.

Foils, plates, paper

Transmission sample holder for color and/or haze measurement of films, plates, papers.

Smallest quantities - cuvettes in all sizes

HunterLab offers a transmission sample clamp with three different holders for macro, semi-micro and ultra-micro cuvettes.

CIE Lab colorimetry

Color measurement in transmission with different sized vials, cuvettes and glasses for quality assurance of all liquid samples.

APHA, Gardner, Lovibond® RYBN

Fast spectral analysis of CIE Lab color values and indices such as APHA, Gardner, Lovibond® RYBN and many other measurement data with the Vista spectrophotometer.

How the Vista® spectrophotometer works

In all these measurements, the Vista® eliminates the subjectivity of visual impressions and increases reproducibility. This enables you to carry out measurements on pharmaceutical products, foodstuffs and plastic products in compliance with standards and to determine the color or opacity in medicines, beverages, concentrates, oils, plates and films in a repeatable and precise manner.

Versatile stationary spectrophotometer

With the right accessories, the compact device is suitable for all laboratory applications. It delivers maximum precision and accuracy and, thanks to its integrated software, is perfect for measuring transparent and translucent samples, for example for the exact measurement of..:

  • Liquids
  • Solids such as films and sheets
  • APHA measurement of resins

as well as in the color determination of solvents, surfactants, acids, paints, oils and perfume. The Vista® also enables you to quickly and easily assess other products such as fuels, kerosene or alcohols according to Saybolt or ASTM D 1500 (mineral oil color number, color value of mineral oil and petroleum products).

Standard-compliant color measurement with integrated QC software for all important indices

The integrated EasyMatch QC Essentials software contains the four best-known pharmacopoeias (Ph. Eur., USP, JP, PPRC) as well as all important indices, for example:

  • PtCo/ Hazen/ APHA
  • Gardner Color, Haze %
  • Opalescence
  • Y Total transmission
  • Saybolt
  • Absorbance
  • CIE Spectral Data

Vista® also enables GMP-compliant work in accordance with FDA CFR 21

Do you work in compliance with FDA CFR 21? HunterLab also offers ER software software. The Vista thus enables you to use the product in compliance with the guidelines and Good Manufacturing Practice (GMP).
