In chromatography, a wide variety of glass or plastic sample vials are used for analytical purposes. Since these are usually used in autosamplers or other automatic instruments, strict adherence to all dimensions is crucial for trouble-free operation in the instrument. In addition, the bottles must also meet requirements for inertness and purity. Here you will find GC and HPLC vials with flat, round and conical bottle bases as well as with different bottle necks, such as bottles with headspace rim and DIN rolled rim, threaded bottles, short threaded bottles and some more.
