VSTAR™ Water & Organic Vapor Sorption Analyzers

The VSTAR™ from Anton Paar is a high-throughput analyzer designed for evaluating up to four samples simultaneously. It features an excellent manifold temperature control that provides improved accuracy.

Available in two- or four-station models, the analyzer ensures maximum flexibility with its independent sample temperature control and wider sample temperature range.

Using VSTAR™ vapor sorption analyzer, a wide range of organic vapors can be analyzed at different temperatures. Precise control of the manifold temperature from the vapor source to the sample avoids local condensation of the adsorptive, providing accurate analysis.

The analyzer also determines complete adsorption-desorption isotherms which is nothing but the quantitative uptake of vapor with respect to relative humidity/relative pressure at a thermostatically controlled temperature.

The acquisition and control of data are controlled using a user-friendly software package. The status of valves, sensors, pumps, etc can be viewed over the controlling PC. The data can be exported to VersaWin™ Anton Paar’s powerful physisorption data processing package or spreadsheets for additional processing or display operations.

Key Features

The main features of the VSTAR™ are:

  • Convenient loading and unloading of samples
  • High throughput and superior manifold temperature control
  • A cold trap prevents vapors from entering the vacuum system
  • Interlocked door prevents opening of the instrument during the experiment
  • Dosing manifold and vapor source in a single thermostatically controlled chamber
  • Ethernet Port for PC control via Windows® based software

This product is a former Quantachrome product. On February 9, 2018, Anton Paar acquired Quantachrome. Under the umbrella of the Anton Paar Group, the company will continue operations in Boynton Beach. Quantachrome is the first manufacturing facility in North America run by Anton Paar and will also function as a US-based unit for research, development, and production within the Anton Paar Group.
