1 mm shell vials typically refer to small, cylindrical vials with a thin outer shell. They are commonly used for chromatography applications, such as gas or liquid chromatography. Micro-vials generally refer to very small vials with a reduced volume capacity. They are often used for storing small quantities of samples or for high-throughput analysis in laboratories.Integrated screw snap crimp vials combine the features of screw vials and crimp vials. They typically have a threaded neck that allows for easy screwing of a closure, such as a screw cap, and also feature a snap-top design that allows for secure crimping.
