Norell, Inc. is pleased to introduce a NMR sample tube product line, featuring a glass/PTFE pressure valve permanently joined to your choice of a wide selection of available NMR sample tubes.
This valve incorporates an advanced seal design that is superior to alternative valves currently available from other manufacturers. A fluoroelastomer o-ring imparts resilience and a high degree of chemical resistance. A PTFE sheath, forming the primary seal, completely covers the fluoroelastomer o-ring, creating the ultimate barrier against aggressive, reactive substances while providing a totally inert surface.
Now available for automated systems as well as with Ultra-Thin walls.
