SCAT Lab Safety NS29/32 HPLC Safety Cap

SCAT Lab Safety NS29/32 HPLC safety cap is a hermetically sealing stopper with a lock nut that allows it to be easily loosened and removed, even after a long standing time. The locknut is designed to press against the bottle when it is turned, releasing the cap without much effort. These safety caps have a 29/32mm standard ground joint to fit on ground neck laboratory bottles and come with a locknut and 3.2mm outer diameter PFA fittings to provide secure capillary connections.

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.
