Shigemi Advanced NMR Microtube Assembly, Matched with CDCl3, Z529087, Shigemi (CAT#: STEM-L-2154-Y)

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.

Material: glass tube
Manufacturer: Shigemi, CMS-005TB
Parameters: 900 MHz frequency
Bottom L: 8 mm
External sample tube outer diameter: 5 mm
Size: 180 mm
Tube diameter: 5mm

• Thinner 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 1.2
• 16% better signal to noise ratio than symmetric tubes
• Despite the increased sample volume, artifacts caused by the RF inhomogeneity are very limited and increased sensitivity is expected
• Suitable for 900 MHz NMR instruments
• 5 mm O.D. tubes: insert: 190.0 L × 4.1 mm O.D.; outer sample tube: 180.0 × 4.965 mm
• 8 mm O.D. tubes: insert: 200.0 L × 6.9 mm O.D.; outer sample tube: 190.0 × 8.0 mm
