The handling of the processed samples also belongs to the sample preparation. For this purpose, the samples are transferred into suitable sample vials with closure, from which the sample is directly applied and subsequently injected for analysis. After sample processing, the sample solution is transferred into a suitable sample vessel and sealed to prevent evaporation of the sample until the injection time. For an optimal analysis, it is also necessary to take into account the quality of the sample bottles and septa of the closures.
In our range, you will find vials with the following closures: headspace edge (chamfered edge), DIN roll edge (flat edge), special roll edge for SPME vials (thicker roll edge), snap ring, melted edge (flat bottom glass), short thread ND9, fine thread ND18 for headspace and SPME, snap lid edge (sample storage vessel, no autosampler bottle).
When designing the vial bottom you can choose between the following bottoms: flat bottom, rounded bottom (HS bottom), round bottom, conical bottom, solid glass bottom and a microliter bottle with inner cone.
In the following excerpt from our current catalog you will find an overview of the most important vial types listed above:
You can also find a selection of sample vials with different bottoms designs in our Analytics-Shop. An overview of the most important types is shown below:
