Open top caps can be used with any 8mm septa Phenolic caps are suitable for autoclaving and low temperature applications Polypropylene caps are chemically inert and suitable for most chromatography applications Kim-Lok™ cap/septum assemblies feature a molded centering ring to eliminate septum movement during injection
Screw caps used on chromatography vials are either 8mm, 9mm, or 10mm, with 9mm being the most popular size. Vials can have a standard opening (5mm) or wide-mouth opening (6mm) depending upon the cap type to be chosen. Always choose a vial that is appropriate for the specific instrument in use. For example, 11mm crimp and 9mm screw-cap vials

Although most laboratories have switched to 9 mm screw thread vials for a wider opening while still being autosampler compatible, some labs use 8-425 vials for storing solvents. The standard opening 8-425 vials have more threads per inch, so there is less likelihood that volatile solvents will evaporate over time.

The caps feature different finishes and septa materials for gas or high performance liquid chromatography applications. Maintain a clean and safe workplace using the spill-free chromatography vial closures available in various sizes and styles to be compatible with autosampler operation.
For screw thread vials, a two part number is assigned. For example, 8-425 neck finish represents a vial with a diameter of 8 mm across the outside of the threads and a thread style of 425. Screw thread vials and caps are more expensive than crimp seals. Caps for screw thread vials are available with either an open hole for autosampler use and
