Needle Sharpness & Puncture Resistance Testing

Hypodermic needles are tested to determine how their design influences the ease of insertion into the skin, patient pain and skin trauma. They are also tested to determine their efficacy in piercing elastomer closures on vials. Sharpness is determined by measuring the penetration force of a needle into a known medium which closely replicates skin as well as actual elastomer caps.

The ‘hardness’ of elastomers is also measured to ensure smooth needle penetration without ‘blunting’ the needle.
