Gemini VII 2390 automatic rapid surface area and porosity analyzer

Gemini USES innovative design to ensure that sample and balance tubes, sample and reference gas storage tanks and their associated piping are located in the same conditions.
During the analysis, the pressure difference between the gas storage tanks is monitored.
This Shared model ensures that any pressure difference is entirely due to sample adsorption and not to changes in free space during analysis.

Windows that guide installation video and system validation tests ensure required performance and reliability.
Operation instruction video can be displayed on the instrument screen to instruct the user
Eliminates free volume errors due to thermal variations or initial measurement errors
By eliminating free volume error (FV), which is a limitation of static volumetric method, the low surface test can be carried out without krypton gas
Since the absorption rate of the sample controls the intake rate of the analytical gas, the specific surface analyzer analysis speed reaches the speed allowed by physical adsorption

Servo valves control the rate of gas entering the sample tube to ensure that the target pressure is not overpressurized, accurately obtain the target pressure and prevent the sample from boiling
Three software control modes: embedded software and a keyboard make Gemini VII independent of an external computer.
