The ASAP 2020 is the standard platform for physi-sorption, gas porosimetry, surface area measurements and with accessories – a range of other tests.
This small point is important, as there is no possibility of vapor cross contamination. It costs more to build, but it is a solid investment.
Like wise, the internal gas lines are all short, with several metal manifolds used to minimise dead volumes, maximise thermal stability and reliability. There are NO needle valves or T pieces.
A unique Micromeritics feature is their use of Isothermal jackets on the sample tubes, rather than elevator control, to minimise Liquid Nitrogen level errors.
These jackets wick the liquid along the tubes ensureing all parts are at 77.3K. There is a You Tube video on the backgound to this with Dr. Jeff Kenvin.
and the ability to connect to a mass spectrometer.
New ASAP 2020 version 3.00 software provides options specifically designed to help fuel cell and hydrogen storage researchers.
