Wilmad-Lab Glass 507-PP-9SUP-5 Thin Wall Precision Suprasil NMR Sample Tube, 5 mm OD, 9" Length, 300 MHz (Pack of 5)

Wilmad precision nmr suprasil (synthetic quartz) tubes are manufactured from high purity synthetic fused Silica materials with <0.005ppm fe2o3 and outstanding optical characteristics in the deep UV to the near IR.

• Transmission rate from 190Nm to 2600Nm is well over 95 percent (10Mm thickness) excluding reflection
• Possesses a similar thermal expansion rate and tensile strength as natural quartz which is 14 times more robust during the cooling/heating process than type 1 class a glass
• Tight id and od tolerance as small as 0.0065Mm accommodates wilmad inserts
• To maximize snr, wilmad precision nmr suprasil tubes have minimal paramagnetic impurities that would impact shimming
• Manufactured in a state-of-the-art iso 9001:2008 usa facility using a unique precision shrinking and grinding process to shape the inner surface with maximized filling factor
