Method (cont.)• Compare needle quality before and after penetrationinto the vial adaptor septum:○○Group A*: simulation of real use (N=32)tested once following removal of the RNS, and thenafter a single penetration into the Vial Adaptor Septum (TPE)Group B: excessive number of septum penetrations (N=3)tested after 12 septum’s penetrations, and after re-coatingwith silicone oil (explore wiped away silicone effect)• Needle tip investigation for damages by usingx30 magnifying microscope40* Note: another group (N=32) was used for the 2 nd option ofSeptum material (as material not selected – these results are notshown).
