A handy and inexpensive vial/closure combination for uncritical analyses. Star-shaped diaphragm enables easy penetration of the PE-Plug. Recommended for HPLC usage. For the 1ml Shell Vials a plug with and one without insertion barrier for Micro-Inserts is available. The one without barrier shows a better valve effect with regard to the formation of a vacuum. Shell vials and the appropriate plugs can also be supplied as a 2in1 KIT.
