3P micro - Model 200 -Automatic Volumetric Sorption Device
The 3P micro 200 is a fully automatic volumetric sorption device for measuring the adsorption and desorption of nitrogen and other non-corrosive gases, simultaneously on two independently working measuring stations. Optionally with turbomolecular pump and low pressure sensors for micropore measurements and krypton sorption. Depending on the customer`s requirements, the measuring device can be equipped with two mesopore stations (A version), a micro and mesopore station (B1 and B version) or with two micropore measuring stations (C1 and C version). Each measuring port has its own manifold (dosing unit) for an optimal measuring time. Regardless of whether you start one or two measurements, the measurement time is exactly the same! Each station is ap 0- Cell assigned with its own pressure sensor.
The stations work independently of one another, measurements can be restarted at any time. Two separate gas stations are installed in the 3P micro 200 which can be operated in parallel to the measuring stations.
- 2 independent measuring stations
- 2 independent manifolds for fast measuring times
- 2 separate sample preparation stations with integrated cold trap
- easy upgrade to versions B or C
- A separate pump system for the gas station is optionally available
- In addition to nitrogen, other adsorptives can also be measured, such as CO 2 , Ar, Kr, H 2 , O 2 , CO, NH 3 , CH 4 (10 gas inlets)
