1) Description
Butyl Septas are typically made from butyl rubber. Butyl rubber is a synthetic rubber with good gas barrier properties, heat resistance, chemical resistance and aging resistance. They are mainly used to seal chromatography injection bottles to prevent sample evaporation and contamination. In chromatography techniques such as gas chromatography (GC) or high-performance liquid chromatography (HPLC), maintaining sample purity and stability is crucial.
2) Application
Gas Chromatography (GC) and High Performance Liquid Chromatography (HPLC): In these techniques, sample purity and stability are key to obtaining accurate results.
Sample Protection: Prevent samples from contamination or degradation prior to analysis, especially when analyzing sensitive compounds.
High Temperature Applications: Used in experiments that require heating of samples for evaporation, concentration, or other processing.
Long-term Storage: For samples that require long-term storage, butyl septas can effectively prevent sample evaporation and chemical changes.
Automated Sampling: In automated chromatography systems, butyl septas can ensure that samples are not contaminated during the sampling process.
