Inspecting a syringe
Before installing a syringe:
Roll the syringe on the edge of a clean flat surface. If the tip of the needle
moves in a circle, straighten the shaft by bending it slightly near where it
connects to the syringe barrel and check it again. See
Figure 41. Syringe needle inspection
Check for a rough needle. The needle surface may have closely spaced
concentric ridges that act like a miniature file and abrade pieces of the septum
into the inlet or vial. The ridges are easy to see under 10X magnification.
If there are ridges, polish the needle by pulling it through a folded piece of fine
emery paper between your finger and thumb until the ridges are gone. Be
careful not to modify the tip of the syringe.
