Level 3 incorporates additional chemical and solvent resistance over Level 1, Level 2, and the traditional High Pressure Valved NMR Sample tubes, by the substitution of Kalrez® perfluoroelastomer o-ring(s) in place of the standard fluoroelastomer o-rings.
Level 3 utilizes two Kalrez® perfluoroelastomer o-rings, offering the ultimate level of physical and chemical resistance with the inclusion of a secondary, backup o-ring.
