Is carryover an issue

Another important consideration is whether stainless steel medical device tubing is disposable or reusable, and whether residue is an issue if it is reusable like most metals.

In 2015, for example, a deadly outbreak of CRE bacteria was linked to leftover contamination in duodenoscopes, specialized endoscopes used by about half a million patients a year. Several hospitals have found that duodenoscopes can accumulate bacteria that aren't always removed by routine cleaning, spreading infections from patient to patient.

For such applications, it may be important to specify stainless steel tubes with the smoothest POSSIBLE ID surface finish. The smooth ID makes pipes easier to clean and helps reduce the chance of spreading infections through residual contamination in reusable pipes.

Are there any other surface finish requirements?

In liquid distribution systems, smooth IDS that clean pipes correctly also help reduce the overall cost of testing and improve test accuracy through more accurate sampling.

In addition, regardless of the importance of smooth distribution of the liquid, the smooth ID helps prevent the liquid from spinning, eddying, or shaking as it is removed from the stainless steel tube. Read more about liquid distribution systems.

A smooth finish on the outer diameter (OD) of the medical device tube is also important if the application requires suction, where the entire tube is inserted to absorb the vacuum; However, outer diameter surface finish is not an important factor in the dispensing process.
