Sigma Aldrich Fine Chemicals Biosciences Shigemi Advanced NMR micro1EA

Supplier:  Sigma Aldrich Fine Chemicals Biosciences Z5294511EA

Shigemi NMR microtubes offer high precision quality in NMR spectroscopy.The NMR microtubes are made out of a special type of hard glass wtih excellent chemical durability and are magnetic susceptibility matched to each of the solvents they are identified with.The Advanced NMR microtube consists of outer tube and insert and has increased sensitivity with these improved featuresThinner glass wall in the sample area than symmetrical microtube (0.20 mm vs 0.40 mm) increasing the sample capacity held in the Rf region by a factor of 1.216% better signal to noise ratio than symmetric tubesDespite the increased sample volume artifacts caused by the Rf inhomogeneity are very limited and increased sensitivity is expectedSuitable for 900 MHz NMR instruments5 mm O.D. tubes insert 190.0 L x 4.1 mm O.D. outer sample tube 180.0 x 4.965 mm8 mm O.D. tubes insert 200.0 L x 6.9 mm O.D. outer sample tube 190.0 x 8.0 mm
