Manual crimpers and opening pliers
For tightly closing crimp top vials manually, you need an appropriate crimper, for opening the corresponding opening pliers are used. If you have e. g. sample vials with 20 mm rim diameter and the proper crimp caps (e. g. N 20 TB/oA), you can use crimpers N 20 and opening pliers N 20 OE. The crimpers listed below can be adjusted to the respective rim height with the aid of a hexagonal key (except for the N8 crimper).
