Features of Gemini VII 2390

Three Gemini VII Model Options

Gemini VII 2390a This option is ideal for rapid and accurate surface area determinations Also provides standard methods for: single-point and Langmuir surface areas, total pore volume, micropore analysis by the t-method, and much more. Included is the capability to determine statistical thickness surface area (STSA) of carbon blacks. (Refer to ASTM D 6556, ASTM D 3765, ISO/DIS 18852.2, or ISO/CD 4652-2/3.) Gemini VII 2390p Provides additional precision with the addition of a P0 (saturation pressure) tube allowing the user to monitor the saturation pressure of the adsorptive on a continuous basis. The instrument is designed to provide a rapid measurement of the adsorption isotherm. Gemini VII 2390t Gemini Has all the capability of the 2390 with the additional ability to perform a BJH or Dollimore Heal pore size distribution using both adsorption and desorption isotherms of up to 1000 points. This instrument also features a P0 tube as well as a larger Dewar and longer sample tubes for extended analysis.

The Gemini Series of surface area analyzers uses the Static Volumetric Technique to generate high-speed surface area and porosity data.
