Wilmad-LabGlass Highthroughput 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.
High Throughput NMR tubes have an averaged camber of 60 micron to
gurantee the spectrum reolution for small melecules (MW<250)
samples up to 600 MHz. Item is sold in plastic twist pack of 50 or
paper pack of 100. Caps are not included and are purchased separately.
The twist pack is made of polypropylene and resistant to common
organic solvents. The packing materials are 100% recyclable.
Some of our competitors altered our MHz rating standard by
advertising inferior tubes for higher magnetic field experiments.
Please visit our NMR
Tube Cross Reference Guide to make a head-to-head
comparison including pricing. The products listed on the same row
will have the same performance at the same magnetic field IF the
specifications of our competitors' product are guaranteed as
advertised. From this guide we will prove our 60 year philosophy
again as "committed to providing customers with cost-effective NMR
consumables of the highest quality".

Note 1: Impact on shimming quality varies upon magnetic field
strength. Economy tube is recommended for 1D low field
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.
