Due to their distinctive blunt bevel design, BD Blunt Needles are intended to decrease needlestick injuries. Syringe filters on blunt filter needles help to lessen glass particle contamination when preparing medications. 98% of the particulate matter is captured by a 5-micron filter that they have. In comparison to conventional needles, the blunt design ensures that up to ten times more force is needed to puncture the skin. It features needles that are 1.5 inches long and 18 gauge in size.
