Vial Kits and other combinations (pre‑crimped / ​pre‑screwed).
While Vial Kits are a convenient packaging format of 100 vials and 100 caps, you can order pre‑sealed vial‑closure combinations (pre‑crimped / ​pre‑screwed) as well. Certificates of Conformity (CoC) can be requested for every vial or closure product.
