    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 surface DX

The 3P surface DX is a fully automated gas sorption analyser with four parallel operating analysis stations for rapid BET surface area determination. The instrument operates without a vacuum system but works with the dynamic principle (flow method). Both Single- and Multipoint-BET measurements can be carried out reliably and in very short times suitable for production and quality control. Use of reference comparison methods keeps the detection time of adsorption peaks extremely short.
