Micromeritics has released the Gemini VII 2390 Series Surface Area Analyzers, which quickly produce accurate and repeatable surface area and porosity results.
The twin-tube design of the Gemini VII series ensures fast and accurate dosing of the adsorptive gas without pressure overshoot.
The design also negates free-space errors introduced by thermal gradient variations or by initial miss-measurement of free space.
The Gemini VII 2390 is available in three model options.
The Gemini VII 2390a is ideal for rapid and accurate surface-area determinations.
It provides standard methods for: single-point and multipoint BET and Langmuir surface areas and total pore volume and micropore analysis by the t-method.
The Gemini VII 2390p incorporates a saturation pressure tube, providing additional precision.
This allows the user to continually monitor the saturation pressure of the adsorptive.
The Gemini VII 2390p quickly measures the adsorption isotherm.
The Gemini VII 2390t has all the capability of the 2390p but can also 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 saturation pressure tube as well as a larger Dewar and longer sample tubes for extended analysis.
All Gemini VII models permit low-to-high surface-area measurements without needing gases such as argon or krypton.
Each model can operate on its own or can be connected to a computer that runs Micromeritics's Gemini VII Windows software, which expands data reduction and reporting capabilities.
Micromeritics's optional confirm software addresses the requirements of 21 CFR Part 11 validation, security, audit trails and reporting.
The Gemini VII 2390s are ideal for teaching, research and quality-control environments.
