VSTAR™

BRAND :

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 temperaturerange provide maximum flexibility; and a high-vacuum option enables analysis of microporous materials. - See more at:
