Why does Dr. Roller say: "Do not reuse and do not resterilize"?

[Annes]

Hello, I just bought Dr.roller. I am asking, if I can use it more than once ewen though in manual it says "do not reuse" and "do not resterilize"

Certainly you can do that. The manufacturer simply covers their bases legally, since if they implicitly endorse reuse they may be legally liable when a practitioner uses a roller on a HIV-positive person and an hour later uses it on another person.

There is absolutely no reason why you can't reuse your own roller or why you can't sterilize it, except that autoclaving would of course melt the plastic. So this disclaimer is also just a way of avoiding claims of damaged rollers. Sterilization = using heat above the boiling point of water for a long time. Sterilization is something else than disinfection, which is what you should do with the roller, using alcohol or Chloramine-T.
