Broken glass

•
In the event of broken glass the glass splinters and leaking centrifugal material are to be carefully removed from
the centrifugal chamber and from the containers or container drillings.
•
Replace the rubber inserts.
The rubber inserts of the container must be replaced after breakage of glass, because any remaining
glass splinters in the rubber cores could cause further breakage of glass.
•
If this concerns infectious material, a disinfection process is to be executed immediately.
