Screw cap, N 13, PP, black, hole, sil. white/PTFE blue, cross-cut 1.5mm

Description

This 13 mm cross-slotted screw cap provides a penetration aid for the thick and blunt HPLC needles, as these could otherwise push the septum into the bottle. In addition, the cross slot prevents the formation of a vacuum in the bottle during multiple injections.
