Why all you guy's believe that those are filter fibers? This is dust form dirty vials. They simply use vials directly from manufacturer without washing and sterilizing it, like food manufacturers do with bottles, jars, etc.
Why would you believe this is any more or less likely than them dialing up the vacuum to increase the flow of their filtration to improve production throughput but occasionally pulling filter fibers off of the back of the filter?
