Constricted Select Series NMR Sample Tubes, 1 Pack
Constricted NMR tubes offer a convenient way to seal your sample from air or other contaminants. Simply heat the constricted portion using a suitable heat source (e.g. a small butane torch) then gently twist and pull on the open end to seal. Also allows samples to be stored under vacuum or inert gas. (Please note: constricted tubes are specified and ordered by the required finished length and are measured from the tube bottom to the center of the constriction.)
Available with ULTRA-THIN wall NMR Tubes.
