"solar filter"

Blunt needles require a higher puncture penetration force than a conventional sharp, so they are less likely to cause needlestick injuries while preparing and filling medications from vials, ampoules, and IV bags.

BD filter needles feature a molded-in 5-micron filter membrane that reduces larger particles during fluid aspiration, reconstitution or transfer, and during medication withdraw from glass reservoirs.

The Sol-M Blunt Fill Needle reduces the risk of needlestick injuries to healthcare workers when drawing up and preparing medication by removing the need for sharps.
