1) Description
Rubber septa are most commonly used to seal medicinal vials containing either a liquid or freeze-dried solid.It is installed along the inside of a cap, which is typically made of metal or plastic.
Rubber septa to seal vials used to store samples in a lab,these vials are typically used in conjunction with either a gas or liquid chromatography.Sealing the injection port on top of a gas chromatography,these injection port septa are meant to seal the entire chromatographic column.
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.
