  • Measure, analyse, control


    Measure, analyse, control

    The systems we supply are used at all stages in research, development and manufacturing

    Our systems enable you to measure, analyse and control a broad range of properties and characteristics across a wide range of sample types.

3P meso series

The 3P meso series of instruments offers fully automated volumetric sorption analysis with Nitrogen and other non-corrosive gases (e.g., CO2, Ar, Kr, H2, O2, CO, NH3 or CH4) on one, two or four analysis stations, respectively. It allows the characterization of mesoporous materials at a minimum of space requirements.

The 3P meso 112 is capable of measuring one sample while at the same time carrying out an in-situ degassing of a second sample. At the end of both the analysis and the degassing process, the heating mantle is switched with the dewar and the analysis continues on the second sample. Alternatively, both stations can be used for sample activation.

A two-station analysis setup with integrated sample preparation is also available with the model 3P meso 222. This system allows simultaneous analysis of two samples.

The 3P meso 400 is a compact sorption analyser with four completely independent analysis stations for the determination of BET surface area, total pore volume and pore size distributions of meso- and macroporous materials. Each analysis station can be programmed individually and started at any given time. This is achieved by four independent dosing volumes and without any time loss.
