Kimble Chase, a manufacturer of laboratory glassware products, produces Kontes-brand NMR tubes with strict adherence to standards to assure that wall thickness, concentricity and camber are exact.
To keep their NMR tubes from spinning out of control, researchers performing NMR spectroscopy require tubes manufactured with uniform precision.
Kimble Chase offers a large selection of NMR tubes, including 3, 5 and 10mm diameters, round- or flat-bottomed tubes and speciality tubes equipped with valves or threaded openings.
All Kontes-brand NMR tubes are constructed of KIMAX borosilicate glass with two grades available to meet individual needs.
KG-33 glass is the lowest thermal-expansion glass tubing offering the highest degree of thermal shock resistance for high-temperature applications, while N-51A is low thermal-expansion glass tubing to accommodate ambient temperature applications.
Available NMR tube closures include pressure caps comprised of polyethylene or PTFE, and red or white rubber septa.
Polyethylene pressure caps are supplied with tubes ordered and with caps included.
Kimble Chase provides researchers with accessories that include manifolds, racks, funnels, pipettes and tube washers.
