22mm autosampler vials china
This series of 22mm autosampler vials is designed for use in Shimadzu autosampler and storage. Used with 20-400 threaded caps and septa, consistent flat bottom.
The 20-400 septum uses only high-quality materials to ensure proper function, especially for liquid chromatograph applications, ensuring that the septum does not fall into the 22mm autosampler vials during the injection process. These septa are made of PTFE/silica gel blends, which are excellently inert and can be injected multiple times. The 20-400 septum has a thickness of 1.5 mm and PTFE is approximately 0.1 mm.
The 20-400 caps are made from high-quality polypropylene, combining innovation with time-saving convenience. This patented, chemically inert cap is a true combination of the septum and the plastic lid at the molecular level to avoid excessive evaporation and maintain proper sealing of the vial.
