Molecular Contamination Control services

Laboratory service

The molecular media test rig and the unique full-scale chemical filter test rig at our corporate head-quarters in Trosa, Sweden and Ipoh, Malaysia are examples of the significant investment made in the field of molecular filtration. In this unique facility, full size gas filters operated in the rig under a wide range of temperature and humidity conditions and challenged with different gases according to ISO 10121-1 and 10121-2. The efficiency and life are determined using an array of sophisticated gas detection equipment.
