The Vstar™ is available in one-, two-, three-, or four-station models, each of which is available with a variety of options. The ability to analyze up to 4 samples simultaneously (on the Vstar™ 4) provides unprecedented throughput; superior manifold temperature control ensures the highest accuracy; independent sample temperature control (with additional circulators) and wider sample temperature range provide maximum flexibility; and a high-vacuum option enables analysis of microporous materials.
Dosing manifold and vapor source in single thermostatically controlled chamber
Ethernet Port for PC control via Windows® based software
Interlocked door to prevent opening during experiment
Cold trap to prevent vapors from entering the pump
Easy loading and unloading of samples
The VSTAR™ vapor sorption analyzer goes beyond water sorption to provide vapor sorption analysis using a wide variety of organic vapors at a wide range of temperatures. Meticulous control of the manifold temperature from the vapor source to the sample eliminates the possibility of local condensation of the adsorptive and ensures the most accurate analysis possible. The VSTAR™ measures complete adsorption-desorptio
n isotherms, that is the quantitative uptake of vapor as a function of relative pressure / relative humidity at a user selectable, thermostatically controlled temperature. Such measurements are of critical importance to material scientists developing adsorption based technologies for chemical process and environmental applications.
