Use a Serum Finish Vial with Crimp Caps
While MicroSolv sells 3 types of vial closures and vials; Screw thread, Snap Top and Crimp Top. Crimp Caps will provide the most effective seal with a serum finish, Crimp Top Vial and 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 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. 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.
