Production uniformity assures entire line of NMR tubes meets quality standards
To keep their NMR tubes from spinning out of control, researchers performing NMR spectroscopy
require tubes manufactured with uniform precision. For many years, scientists have relied on
Kontes brand NMR Tubes, and that legacy continues today with Kimble Chase.

Kimble Chase, the largest manufacturer of laboratory glassware products worldwide, produces
Kontes brand NMR tubes with strict adherence to rigorous production and quality standards to
assure wall thickness, concentricity and camber are exact. A large selection of NMR tubes are
available, including 3mm, 5mm and 10mm diameters, round or flat bottomed tubes, and specialty
tubes equipped with valves or threaded openings. All Kontes brand NMR tubes are constructed of
KIMAX® borosilicate glass with two grades available to meet every scientistʼs needs; KG-33 glass
is the lowest thermal expansion glass tubing offering the highest degree of thermal shock
resistance for high temperature applications; and, 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 with caps
included. Kimble Chase provides researchers with accessories that include manifolds, racks,
funnels, pipettes and tube washers. Kimble Chase is the leader in market share for reusable,
disposable, specialty and custom scientific glassware. Specialty glass apparatus for NMR
spectroscopy are referenced in ASTM, USP and AOAC and APHA procedures.
Kimble Chase manufactures Kontes brand NMR tubes in U.S. facilities that comply with ISO-9001
quality management standards. Because all glass items from the company are crafted initially
from sand, product quality is monitored from raw material through finished product. Kimble Chase
NMR tubes and accessories are available from worldwide distribution facilities. Sales teams are
located in North America, Latin America, Europe, the Middle East, Africa and Asia. For more
