To prevent coring, you should: a. pierce the septum at a 90-degree angle, with the bevel down . b. pierce the septum at a 45-degree angle, with the bevel down . c. pierce the septum at a 45-degree angle, with the bevel up d. pierce the septum at a 90-degree angle, with the bevel up
The rubber caps were then pierced with either an18-gauge sharp hypodermic needle or a blunt plastic (safety) needle. Coring occurred in 102 of 250 (40.8%) vials when a blunt needle was used versus 9 of 215 (4.2%) vials with a sharp needle (P < 0.0001). A significant incidence of coring was demonstrated when a blunt plastic safety needle was used.

To prevent coring, the needle should be inserted at a 45–60° angle with the opening of the needle tip facing up (i.e., away from the stopper), sometimes referred to as “bevel up”. A small amount of pressure is applied, and the angle is gradually increased as the needle enters the vial. The needle should be at a 90° angle just as the
