To Determine if the Surface Finish from Different Materials Influences the Microbial Recovery when Sampled with a Contact Plate

The recovery of naturally occurring surface microbial contamination with sterile tryptone soya agar 55mm diameter RODAC plates had previously been evaluated for five different typical cleanroom related materials. The recoveries were shown to vary and to understand the influence that the surfaces have on the recovery efficiency, further investigation of the surface finishes and roughness values was completed and correlated with the recovery efficiencies determined for the diff
