24mm screw pp cap

The screw cap vial is easy to handle. Tightening the lid with your hand and a mechanical arm will exert mechanical force, which will squeeze the septum between the glass vial and the lid. The screw cap forms an excellent seal and mechanically fixes the septum in place during the piercing process. No tools are required for assembly.

Caps for screw thread vials are available with either an open hole for autosampler use and standard addition or with a solid top for sample storage. One piece polypropylene cap and membrane are also available. These pierceable screw thread caps are designed for one time use and reduce sample preparation time as there is no cap and seal to assemble.
