Designed to improve sample handling during the investigation of volatile, air-sensitive, or toxic compounds. Kontes® HI-VAC® valve maximizes sample recovery. Greaseless valve features a borosilicate glass body and PTFE plug so that the sample is always in contact with inert materials. Rotationally symmetrical design, with two lateral ports located near the valve seat, permits use at higher temperatures. FKM o-ring seal is used to connect the valved NMR tube to a vacuum system. Suitable for use in instruments with field strengths greater than 360 MHz.
