Vapor Pressure Evaluation System VPE-9000<vacuum thermobalance>

Stable changes in weight in a high vacuum
This system evaluates saturated vapor pressure and the thermal behavior of organic materials. An exhaust method is employed that allows stable measurements even in a vacuum. Achieves precise temperature controllability and responsiveness with the Infrared Gold Image Furnace
