Manometric (static, volumetric) analyzer for gas and vapor physisorption measurements. Typical vapors include water, alcohols, and aromatics. The vapor generator is housed within the manifold chamber... heated and thermostatically controlled. A solenoid valve opens the pump ballast for all-important venting of condensible vapors. The vapor option is available on all models of the Autosorb-iQ, one- and two-station versions.
