Picture
Septa Selection
PTFE/Silicone Septa: It has the corrosion resistance of PTFE and the sealing performance of silicone. The high temperature resistance range is usually -40~-200°C. For normal-phase solvents with strong penetrability, such as n-hexane, methylene chloride, etc., it will cause swelling if the liquid level is too high.
PE Septa: The most economical, suitable for storing non-corrosive samples, but it is not recommended for long-term storage of liquids, it is recommended to store at room temperature.
Cap Selection
Thread: Typically suitable for LC and LC/MS applications, provides a low evaporation, reusable, no tool needed. Screw top vial caps are available in both caps designed for automated sampling and solid top caps designed for storage.
Crimp: Best suited for GC and GC/MS applications and volatile compounds.
It provides the best seal for long-term storage when properly crimped.
Snap: The sealing performance is not as good as the above.
Plug: It is sealed with a PE stopper, and the sealing and corrosion resistance are average, but it is economical and convenient. only available with certain autosamplers.
Cap pre-bonded with septa: it has good chemical inertness. Even if it is in contact with concentrated acid, alkali or strong oxidant at high temperature, it will not be affected.
At the same time, the elasticity of the silicone can ensure the sealing performance; It can also ensure that the septum will not be separated from the cover during transportation.
Keeps the septum from poking into the vial, even with thick and blunt syringes.
