Background

The Micromeritics Gemini V Series of surface area analyzers utilizes a patented twin-tube design which assures fast and accurate dosing of the adsorptive gas without pressure overshoot. Paired with the extended capabilities of the embedded software and the powerful new Windows control option, data archiving, and reporting software option, the Gemini V Series offers an extended range of capabilities, and is capable of performing measurements on materials with low surface area without requiring the use of krypton.

Gemini V Models

There are two models in the Gemini V Series, enabling you to get the analyzer that best suits your specific needs. Capabilities are further expanded on each model if the Windows software option is included.
Gemini 2365

The Gemini 2365 determines single-point and multipoint BET and Langmuir surface areas, total pore volume, and micropore analysis by the t-method. Also included is the capability to determine statistical thickness surface area (STSA) of carbon black (refer to ASTM D 6556, ASTM D 3765, ISO/DIS 18852.2, or ISO/CD 4652-2/3).
Gemini 2380

The Gemini 2380 has all the abilities of the Gemini 2365 and additionally can provide BJH pore volume distributions. Up to one thousand isotherm data points may be collected.
