We sell 3 types of vial closures and vials; Screw thread, Snap Top and Crimp Top.

Our Snap Top Vials will accept any of our Snap Caps as well as our Crimp Caps and are often called Snap/Crimp Tops in the market place.

However, to ensure the best long term seal we recommend using our  Crimp Top (Serum Finish) Vials. When a quality designed crimp cap is properly applied to these 11mm, ND11 glass vials, the seal offers the best for long term integrity as well as for durability. A calibrated, crimping tool is required for applying the crimp cap to these vials for best results.

**Please note Screw Top Vials will not accept either Crimp or Snap Caps.
