The product description
The caps are made of magnets, precise manufacturing tolerances and controlled manufacturing environments.The gasket is made of the highest quality plastic king and silica gel to ensure the high efficiency of the function.It is especially suitable for the application of gas chromatograph to ensure that the gasket will not fall into the sample bottle during the process of sampling.17.5mm gasket has excellent inertia and repeatable characteristics, with a thickness of 1.5mm and a PTFE of 0.1mm.Combining innovation with time-saving convenience, precise manufacturing tolerances and controllable manufacturing environment.This patented process is made by combining the spacer and bottle cap at the molecular level, avoiding excessive evaporation and keeping the sample bottles properly sealed.
