SCAT Lab Safety GL45 HPLC Safety Cap V2.0 with Shut-Off Valve

SCAT Lab Safety GL45 HPLC safety cap V2.0 with shut-off valve is a hermetically sealing closure with a convenient shut-off that prevents air from entering the capillaries and solvent drips when changing the container. These safety caps feature a GL45 thread that fits on common laboratory bottles and come with 1.6, 2.3, and 3.2mm outer diameter PFA fittings that provide secure capillary connections. The cap features a core that rotates 360° to allow for easier container changes without twisting the capillaries or causing tubes to tangle. They are available with 2 to 6 connections and include PFA fittings for each connection.

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.
