The Gemini VII 2390 Series Surface Area Analyzers from Micromeritics
rapidly and reliably produce accurate and repeatable surface area and porosity
results. The Gemini VII Series retains the immensely successful, patented twin-tube
design of the previous series of Gemini products. This design assures fast and
accurate dosing of the adsorptive gas without pressure overshoot and also negates
free-space errors introduced by thermal gradient variations or by initial mismeasurement
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 also provides
standard methods for: single-point and multipoint BET and Langmuir surface areas,
total pore volume, micropore analysis by the t-method, and much more. The Gemini
VII 2390p provides additional precision with the addition of a 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. The Gemini VII 2390t has all the capability of the
2390p 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 saturation pressure tube as well as a larger
Dewar and longer sample tubes for extended analysis.
All Gemini VII models permitlow to high surface area measurements without requiring
exotic gases such as argon or krypton. Each model option can also be operated
stand alone or connected to a computer running Micromeritics' Gemini VII
Windows® software, greatly expanding data reduction and reporting capabilities.
Also available is Micromeritics' optional confirm™ software which
addresses the many requirements specified by 21 CFR Part 11 validation, security,
audit trails, reporting, and more.
Their low cost, small footprint, speed, accuracy, simplicity of use, reliability,
and ruggedness make the Gemini VII 2390 an ideal tool for teaching, research,
and quality control environments.
