Product Description
Air-sensitive and volatile samples stay protected in this valved NMR tube, which can be connected to a vacuum line, filled under inert gas and sealed without grease. The HI-VAC valve also helps maximize sample recovery after the experiment, which matters for precious compounds.
This listing is for Kimble catalog number 897435-0000: KONTES Valved 5mm NMR Tube, 7", >360 MHz. The tube is borosilicate glass 3.3, and the valve has a glass body with a PTFE plug, so the sample only touches inert materials. A rotationally symmetrical design with two lateral ports near the valve seat permits use at higher temperatures, and an FKM O-ring seal links it to a vacuum system. It is suitable for instruments above 360 MHz, in 7 in and 8 in lengths. LIGHT LABS ships genuine DWK Life Sciences products with knowledgeable support from our Englewood, Colorado team.
