10mm Economy NMR Tube

Wilmad-LabGlass 10 mm Economy NMR Tubes are manufactured from borosilicate glass that meets the ASTM Type 1 Class B standard and recognized as N51A. Due to its nature, this glass has much less thermal-shock resistance than Class A glass used for our Precision Tubes. It may contain Fe2O3 which is paramagnetic around 1200 ppm and has certain impact on shimming quality at high field over 600 MHz. 10 mm NMR tubes have an averaged camber of 60 micron to gurantee the spectrum reolution for small melecules (MW<500) samples up to 600 MHz. 10 mm Economy tube is ideal for MRI imaging applications. Item is sold in a pack of 100.

Application Notes

Material ASTM Type 1 Class B Borosilicate Glass Impact on shimming quality by paramagnetic impurities1 Medium (1200 ppm Fe2O3) Rapid cooling/heating No Max. working temperature Ambient Sample volume reproducibility2 10% Averaged Sample Volume within Rf  coil 600 µl/cm Outer Diameter 9.944±0.025 mm Cut-off wavelength 320 nm Compatible with Small Volume Insert No Recommended Application 1D NMR experiments with small organic molecule (Molecular Weight <1500) below 600 MHz Note 1: Impact on shimming quality varies upon magnetic field strength. Economy tube is recommended for 1D low field experiments. Note 2: Sample volume reproducibility refers to the maximum volume fluctuation when filling different NMR tubes to the same sample height. This number correlates to the reproducibility of time domain signal amplitude between different runs.
