We have performed measurements showing that the permeability of a FFP2 mask is not changed after several cleanings with 99% grade ethanol, allowing the possibility to clean and reuse masks. In this publication, we assess the effect of ethanol on the filtering properties of FFP2 masks. The permeability of parts of a FFP2 mask is measured before and after several cleanings with 99% ethanol (no shear forces are applied). Like for any...

Over the past 10 years, CYDAREX has developed a series of equipment to teach conventional (CCA) and special core analysis (SCAL). This equipment and the know-how are now available. Learn more. „More economical than standard laboratory equipment, but using the same principles; designed to be easy to use, and to visualize flows. „Procedures optimized to provide quick results, within a few hours (Kr) to a few days (Pc/RI). No safety...

In CYDAR 2017, we are introducing a new dispersion / tracer module. Dispersion experiments give indication on the homogeneity of the sample, by analyzing dispersion of an injected solution at concentration Cin with a solution at concentration C0 present in sample. Four models have been implemented: Classical, Koval, Coats and Smith, and Stratified. Temperature corrections and normalization are available.
