How clean are the OELCHECK sample bottles?

We have the hydraulic fluids from our construction machinery analysed on a regular basis with analysis kit 2 for mobile hydraulics. This also includes a particle count in accordance with ISO 4406. How useful is an analysis of this kind if the hydraulic fluid is sent to the lab in a sample bottle that contains particles itself? Are the results of the analysis influenced by the transportation of the sample in the sample bottle? How clean are your bottles? Are you able to provide a statement on how many particles are present in a new sample bottle and how large they are?
