SCAT Lab Safety GLS40 HPLC Safety Cap with Shut-Off Valve

SCAT Lab Safety GLS40 HPLC safety cap with shut-off valve is a hermetically sealing closure designed to block harmful vapors and protect the HPLC system from contamination. These safety caps fit on laboratory bottles with a GLS40 thread and come with a 3.2mm outer diameter PFA fitting to provide a secure capillary connection. The cap features a core that rotates 360° to allow for easier container changes without twisting the capillaries or causing tubes to tangle.

SCAT Lab safety caps are manufactured with chemical-resistant materials and a design that prevents contaminants from entering the HPLC system. Cap components ensure that capillaries and tubes remain tightly screwed in and cannot slip out of the solvent, preventing interruptions due to air pockets. Additionally, the closed system of the cap prevents individual components from evaporating, allowing solvent mixtures to remain stable with a consistent mixing ratio. 

The SCAT Lab safety cap also features an air valve that ensures safe pressure equalization during HPLC operation. It contains a valve membrane that retains dust and dirt particles from the ambient air. This allows analysis results to remain unaltered and reproducible and provides clean separation without interfering with or overlapping peaks in the chromatogram.
