Gemini VII 2390 Series Surface Area Analyzers

Accurate, Fast and Economical Micromeritics' Gemini VII 2390 Series of surface area analyzers rapidly and reliably produces accurate and repeatable surface area and porosity results. Their low cost, high speed simplicity of use, reliability, and ruggedness have earned the Gemini a place in research and quality control laboratories worldwide.

Unique Capabilities
The design of the Gemini provides unique capabilities found only in more expensive products. Many error sources inherent in traditional static volumetric instruments are eliminated through common mode rejection. This provides a more accurate, more precise and more stable measurement tool, therefore providing unique capabilities. For example, using nitrogen, the Gemini is capable of performing measurements on materials with a very low surface area, where similar instruments would require the use of krypton. Krypton is not only more expensive, but for a typical analyzer, measuring a krypton isotherm requires lower pressures than can be achieved with low-cost pumps and requires additional components within the instrument to measure these lower pressures. Without the additional requirements, both the Gemini's price and operating costs remain low.
