Closures N11 snap, PE (hard), transparent, hole, PTFE/Silico

Broad variety of closures in different colors Hard PE caps for better sealing; soft, light blue PE caps for more convenient handling (easy push on and removal of caps) Septa material used for the production of the snap ring closures has – aside from physical inspection – also been tested analytically Red Rubber / FEP septum for routine analyses; for more demanding analyses: high purity silicone / PTFE septa Cross-slit silicone/PTFE septa as a penetration aid for thick / blunt HPLC needles Snap ring vials may alternatively also be crimped with 11 mm crimp closures, if used for GC purposes Packed with 100 pieces in a resealable, tamper-evident zip-lock bag Closures can be ordered as single components or - along with a vial of your choice - as a Vial Kit in a drawer-like PP box for safe storage during consumption in the lab. For all closures, plain caps or replacement septa you can ask for a certificate of conformity (CoC) for your own ISO documentation.
